为了说明本申请的技术方案，下面通过以下实施例来进行说明。In order to illustrate the technical solution of the present application, the following examples are used for illustration.

继续参阅图1，本申请实施例提供一种区块链数据处理方法，包括：Continuing to refer to Figure 1, the embodiment of the present application provides a blockchain data processing method, including:

步骤101，接收操作请求信息。Step 101, receiving operation request information.

其中，上述操作请求信息用于指示对目标区块链上的目标文件执行目标操作。Wherein, the above-mentioned operation request information is used to indicate to execute the target operation on the target file on the target blockchain.

实践中，操作请求信息中通常包括目标文件的文件标识和用于对目标操作进行描述的操作描述信息。实践中，上述文件标识通常为文件名。上述目标操作可以是对目标文件整体进行操作，也可以是对目标文件中的一个或多个数据进行操作。在上述目标操作为对目标文件中的一个或多个数据进行操作时，上述操作请求信息中还可以包括待操作的数据的数据标识。上述目标文件中的数据可以是交易数据，也可以是日志数据，还可以是其它数据。实际应用中，对目标文件或者是目标文件中的数据所执行的操作可以包括但不限于：回滚操作(reset)、删除操作(delete)、复制操作(copy)、恢复操作(restore)等。In practice, the operation request information usually includes the file identifier of the target file and operation description information used to describe the target operation. In practice, the above-mentioned file identification is usually a file name. The above target operation may be performed on the entire target file, or may be performed on one or more pieces of data in the target file. When the target operation is to operate on one or more data in the target file, the operation request information may further include a data identifier of the data to be operated. The data in the above target file may be transaction data, log data, or other data. In practical applications, the operations performed on the target file or the data in the target file may include but not limited to: rollback operation (reset), delete operation (delete), copy operation (copy), restore operation (restore) and so on.

在本实施例中，上述区块链数据处理方法的执行主体通常为上述目标区块链，具体可以为上述目标区块链上的各个区块链节点。实际应用中，每个区块链节点可以实现成终端也可以实现成服务器。In this embodiment, the execution subject of the above-mentioned blockchain data processing method is usually the above-mentioned target blockchain, specifically each blockchain node on the above-mentioned target blockchain. In practical applications, each blockchain node can be implemented as a terminal or as a server.

实践中，上述执行主体可以从通信连接的用户端接收到上述操作请求信息，也可以从其它区块链接收到上述操作请求信息。In practice, the above-mentioned execution subject may receive the above-mentioned operation request information from the communication-connected client, or may receive the above-mentioned operation request information from other blockchain links.

步骤102，根据操作请求信息，从目标位置查找与目标文件对应的目标句柄。Step 102, according to the operation request information, search for the target handle corresponding to the target file from the target location.

其中，目标句柄包括目标文件对应的目标地址。目标位置包括以下任一项：活跃文件、句柄池组。Wherein, the target handle includes the target address corresponding to the target file. Destinations include any of the following: active files, handle pool groups.

其中，上述目标句柄通常是目标文件对应的文件句柄。上述目标地址通常是上述目标文件的文件地址。上述活跃文件通常是区块链节点中尚未上链存储的处于被写入状态的文件。Wherein, the above target handle is usually a file handle corresponding to the target file. The above-mentioned target address is usually the file address of the above-mentioned target file. The above-mentioned active files are usually files in the state of being written that have not yet been stored on the chain in the blockchain node.

实践中，上述句柄池组通常是预先建立的多个句柄池的组合。句柄池组中的句柄池可以有两个也可以有多个。设置多个句柄池，可以实现对各个句柄池中的文件句柄进行独立管理，比如，在某个时间段，可以让一些句柄池正常使用，以及让另一些句柄池对长期未被使用的文件句柄清除。多个句柄池并行工作，可以及时对长期未被使用的文件句柄清除，这样，每个句柄池的容量无需太大。一方面可以保障对目标文件的查找效率，另一方面可以节省所有句柄池所占的存储空间。需要指出的是，上述句柄池通常是用于存放文件句柄的存储空间。句柄池组中的每个句柄池可以实现成数据队列。In practice, the above handle pool group is usually a combination of multiple handle pools established in advance. There can be two or more handle pools in a handle pool group. Setting multiple handle pools can realize independent management of file handles in each handle pool. For example, in a certain period of time, some handle pools can be used normally, and other handle pools can be used for file handles that have not been used for a long time. clear. Multiple handle pools work in parallel, and the file handles that have not been used for a long time can be cleared in time, so that the capacity of each handle pool does not need to be too large. On the one hand, it can guarantee the search efficiency of the target file, and on the other hand, it can save the storage space occupied by all handle pools. It should be pointed out that the above-mentioned handle pool is usually a storage space for storing file handles. Each handle pool in the handle pool group can be implemented as a data queue.

实际应用中，句柄池组中通常包括工作状态相异的两个句柄池，且通常是一个处于活跃状态，另一个处于空闲状态。处于空闲状态的句柄池负责及时清除长期未被使用的文件句柄。处于活跃状态的句柄池负责新的文件句柄的添加及引用等。两个句柄池的工作状态通常可以相互调换。比如，可以在间隔2分钟之后，将原本处于活跃状态的句柄池切换为处于空闲状态，以及将原本处于空闲状态的句柄池切换为处于活跃状态。这样可以实现及时有效地对未使用的文件句柄进行清除，可以进一步节约存储空间。In practical applications, the handle pool group usually includes two handle pools with different working states, and usually one is in an active state and the other is in an idle state. The handle pool in the idle state is responsible for clearing the file handles that have not been used for a long time in time. The active handle pool is responsible for adding and referencing new file handles. The working status of the two handle pools can usually be exchanged with each other. For example, after an interval of 2 minutes, the handle pool that was originally in an active state can be switched to an idle state, and the handle pool that was originally in an idle state can be switched to an active state. In this way, unused file handles can be cleared in a timely and effective manner, and storage space can be further saved.

另外，在每个句柄池中的文件句柄包括文件标识、文件地址和动态引用次数的情况下，可以及时将处于空闲状态的句柄池中动态引用次数为零的文件句柄删除。其中，动态引用次数用于记录相应文件句柄当前被引用的次数。举例来说，若句柄池A中的一个文件句柄1的动态引用次数为5，则表明该文件句柄1当前正在被5个请求方调用。每个文件句柄支持同时被多个请求方调用，实用性高灵活性较好。实际应用中，文件句柄中还可以包括其它信息，比如，还可以包括文件当前状态。文件当前状态可以用于标识该文件句柄对应的文件当前被操作的状态。文件当前状态可以包括操作状态和空闲状态。举例来说，在即将对某个文件进行操作之时，可以将该文件的文件当前状态标记为操作状态，在对该文件执行操作之后，可以将该文件的文件当前状态标记为空闲状态。In addition, when the file handles in each handle pool include file identifiers, file addresses, and dynamic reference times, file handles with zero dynamic reference times in the idle handle pool can be deleted in time. Wherein, the dynamic reference count is used to record the current reference count of the corresponding file handle. For example, if the number of dynamic references of a file handle 1 in the handle pool A is 5, it indicates that the file handle 1 is currently being called by 5 requesters. Each file handle supports being called by multiple requesters at the same time, which has high practicability and good flexibility. In practical applications, the file handle may also include other information, for example, the current status of the file may also be included. The current state of the file can be used to identify the current state of the file corresponding to the file handle being operated. The current state of the file may include an operating state and an idle state. For example, when an operation is about to be performed on a certain file, the current state of the file may be marked as the operating state, and after the operation is performed on the file, the current state of the file may be marked as the idle state.

其中，上述活跃文件，通常是区块链节点中尚未上链存储的处于被写入状态的文件。活跃文件中可以被先后写入多条数据。在活跃文件被写满时，上述执行主体可以将活跃文件的文件句柄写入处于活跃状态的句柄池中。实际应用中，活跃文件的文件句柄写入处于活跃状态的句柄池时，新添加至处于活跃状态的句柄池中的文件句柄可以包括该活跃文件的文件名、该活跃文件被存储在区块链上的文件地址、初始引用次数。其中，初始引用次数通常是预先设定的次数值。实际应用中，初始引用次数通常为0。Among them, the above-mentioned active files are usually files in the state of being written that have not been stored on the chain in the blockchain node. Multiple pieces of data can be written successively in the active file. When the active file is full, the execution subject may write the file handle of the active file into the handle pool in an active state. In practical applications, when the file handle of the active file is written into the handle pool in the active state, the file handle newly added to the handle pool in the active state can include the file name of the active file, the active file is stored in the blockchain The file address and initial reference count on the . Wherein, the initial number of references is usually a preset number of times. In practical applications, the initial reference count is usually 0.

需要指出的是，在当前的活跃文件被写满以及被上链存储时，上述执行主体可以生成用于写入数据的新的活跃文件，以及给新的活跃文件创建对应的文件句柄，以此类推。It should be pointed out that when the current active file is full and stored on the chain, the above execution subject can generate a new active file for writing data, and create a corresponding file handle for the new active file, so as to analogy.

这里，上述执行主体可以采用操作请求信息，从目标位置查找与目标文件对应的目标句柄。Here, the execution subject may use the operation request information to search for the target handle corresponding to the target file from the target location.

作为一个示例，上述执行主体可以采用操作请求信息所包括的文件标识，与活跃文件的文件标识进行比较，若二者相一致，则可以确定当前的活跃文件即为为上述目标文件，此时，可以直接将活跃文件对应的文件句柄确定为上述目标句柄。As an example, the above-mentioned execution subject may use the file identifier included in the operation request information to compare it with the file identifier of the active file. If the two are consistent, it can be determined that the current active file is the above-mentioned target file. At this time, The file handle corresponding to the active file may be directly determined as the above-mentioned target handle.

作为另一个示例，上述执行主体可以采用操作请求信息所包括的文件标识，从句柄池组中，查找对应文件标识与目标文件的文件标识相同的文件句柄，以及将查找到的文件句柄确定为上述目标句柄。As another example, the above execution subject may use the file identifier included in the operation request information to search for a file handle whose corresponding file identifier is the same as the file identifier of the target file from the handle pool group, and determine the found file handle as the above-mentioned target handle.

步骤103，根据目标句柄，查找目标文件，以及对目标文件执行目标操作。Step 103, according to the target handle, search for the target file, and execute the target operation on the target file.

这里，在得到目标文件对应的目标句柄之后，由于目标句柄可以指向目标文件的文件地址，故而上述执行主体可以直接采用目标句柄找到目标文件，以及对目标文件执行上述目标操作。Here, after obtaining the target handle corresponding to the target file, since the target handle can point to the file address of the target file, the execution subject can directly use the target handle to find the target file, and perform the above target operation on the target file.

本实施例提供的方法，由于文件句柄通常可以指向相对应的文件的文件地址，因此，从活跃文件或者是句柄池组查找与目标文件对应的目标句柄，从而通过目标句柄快速查找到目标文件，可以实现快速准确地查找到需要被操作的目标文件，有助于提高对区块链数据的处理效率。In the method provided by this embodiment, since the file handle can usually point to the file address of the corresponding file, the target handle corresponding to the target file is searched from the active file or the handle pool group, thereby quickly finding the target file through the target handle, It can quickly and accurately find the target file that needs to be operated, which helps to improve the processing efficiency of blockchain data.

步骤201，根据预先确定的句柄池尺寸，创建句柄池组。Step 201, create a handle pool group according to a predetermined size of the handle pool.

其中，句柄池组中包括工作状态相异的两个句柄池。工作状态可以包括活跃状态和空闲状态。各句柄池中的文件句柄包括文件标识、文件地址和动态引用次数。其中，动态引用次数用于记录相应文件句柄当前被引用的次数。需要指出的是，在某个句柄池中的某个句柄文件的动态引用次数不为1时，表明该文件句柄正在被多个请求方调用。举例来说，若句柄池A中的一个文件句柄1的动态引用次数为5，则表明该文件句柄1当前正在被5个请求方调用。每个文件句柄支持同时被多个请求方调用，实用性高灵活性较好。Wherein, the handle pool group includes two handle pools with different working states. Working states may include active states and idle states. The file handles in each handle pool include file identifiers, file addresses and dynamic reference times. Wherein, the dynamic reference count is used to record the current reference count of the corresponding file handle. It should be pointed out that when the number of dynamic references of a handle file in a handle pool is not 1, it indicates that the file handle is being called by multiple requesters. For example, if the number of dynamic references of a file handle 1 in the handle pool A is 5, it indicates that the file handle 1 is currently being called by 5 requesters. Each file handle supports being called by multiple requesters at the same time, which has high practicability and good flexibility.

实际应用中，句柄池组中通常包括工作状态相异的两个句柄池，且通常是一个处于活跃状态，另一个处于空闲状态。处于空闲状态的句柄池负责及时清除长期未被使用的文件句柄。处于活跃状态的句柄池负责新的文件句柄的添加及引用等。两个句柄池的工作状态通常可以相互调换。比如，在间隔一段时间后，可以将原本处于活跃状态的句柄池切换为处于空闲状态，以及将原本处于空闲状态的句柄池切换为处于活跃状态。这样可以实现及时有效地对未使用的文件句柄进行清除，可以进一步节约存储空间。In practical applications, the handle pool group usually includes two handle pools with different working states, and usually one is in an active state and the other is in an idle state. The handle pool in the idle state is responsible for clearing the file handles that have not been used for a long time in time. The active handle pool is responsible for adding and referencing new file handles. The working status of the two handle pools can usually be exchanged with each other. For example, after a period of time, the handle pool that was originally in an active state can be switched to be in an idle state, and the handle pool that was originally in an idle state can be switched to be in an active state. In this way, unused file handles can be cleared in a timely and effective manner, and storage space can be further saved.

另外，在每个句柄池中的文件句柄包括文件标识、文件地址和动态引用次数的情况下，可以及时将处于空闲状态的句柄池中动态引用次数为零的文件句柄删除。在每个句柄池中的文件句柄还包括文件当前状态的情况下，可以及时将处于空闲状态的句柄池中的、动态引用次数为零且对应文件当前状态为空闲状态的文件句柄删除。In addition, when the file handles in each handle pool include file identifiers, file addresses, and dynamic reference times, file handles with zero dynamic reference times in the idle handle pool can be deleted in time. In the case that the file handles in each handle pool also include the current state of the file, the file handles in the handle pool in the idle state, whose dynamic reference count is zero and whose current state is idle, can be deleted in time.

其中，上述句柄池尺寸通常可以指示句柄池的容量大小。实践中，上述句柄池尺寸可以是用户端输入的，也可以是默认设置的。需要指出的是，句柄池的容量通常是指句柄池所能容量的文件句柄的数量。Wherein, the above handle pool size may generally indicate the capacity of the handle pool. In practice, the size of the above handle pool may be input by the user terminal, or may be set by default. It should be pointed out that the capacity of the handle pool usually refers to the number of file handles that the handle pool can hold.

实践中，上述句柄池通常是用于存放文件句柄的存储空间。句柄池组中的每个句柄池可以实现成数据队列。In practice, the above-mentioned handle pool is usually a storage space for storing file handles. Each handle pool in the handle pool group can be implemented as a data queue.

这里，上述执行主体可以采用上述句柄池尺寸，创建多个句柄池，从而得到上述句柄池组。举例来说，若句柄池尺寸指示句柄池的容量大小为100，则上述执行主体可以分配一块能够容纳100个文件句柄的存储空间，该存储空间即为句柄池。Here, the above-mentioned execution subject may use the size of the above-mentioned handle pool to create multiple handle pools, so as to obtain the above-mentioned handle pool group. For example, if the size of the handle pool indicates that the capacity of the handle pool is 100, the execution subject may allocate a storage space capable of accommodating 100 file handles, and the storage space is the handle pool.

需要指出的是，句柄池组中的每个句柄池的大小相同，便于管理与维护。另外，缺省情况下，句柄池为空，也即是，未被使用的情况下，句柄池中没有存储文件句柄。It should be pointed out that the size of each handle pool in the handle pool group is the same, which is convenient for management and maintenance. In addition, by default, the handle pool is empty, that is, if it is not used, no file handle is stored in the handle pool.

步骤202，接收操作请求信息。Step 202, receiving operation request information.

其中，操作请求信息用于指示对目标区块链上的目标文件执行目标操作。Wherein, the operation request information is used to indicate to execute the target operation on the target file on the target blockchain.

步骤203，根据操作请求信息，从目标位置查找与目标文件对应的目标句柄。Step 203, according to the operation request information, search for the target handle corresponding to the target file from the target location.

其中，目标句柄包括目标文件对应的目标地址，目标位置包括以下任一项：活跃文件、句柄池组。Wherein, the target handle includes the target address corresponding to the target file, and the target location includes any of the following items: active file, handle pool group.

步骤204，根据目标句柄，查找目标文件，以及对目标文件执行目标操作。Step 204, according to the target handle, search for the target file, and execute the target operation on the target file.

在本实施例中，步骤202-步骤204的具体操作与图1所示的实施例中步骤101-步骤103的操作基本相同，在此不做赘述。In this embodiment, the specific operations ofsteps 202 to 204 are basically the same as the operations ofsteps 101 to 103 in the embodiment shown in FIG. 1 , and will not be repeated here.

本实施例可以创建两个工作状态相异的句柄池，一个处于活跃状态，另一个处于空闲状态。处于空闲状态的句柄池负责及时清除长期未被使用的文件句柄。处于活跃状态的句柄池负责新的文件句柄的添加及引用等。两个句柄池并行工作，且两个句柄池的工作状态可以相互调换，可以实现及时将不被使用的文件句柄清除。这样，每个句柄池的容量无需太大，一方面可以保障对目标文件的查找效率，另一方面可以进一步节省所有句柄池所占的存储空间。In this embodiment, two handle pools with different working states can be created, one is active and the other is idle. The handle pool in the idle state is responsible for clearing the file handles that have not been used for a long time in time. The active handle pool is responsible for adding and referencing new file handles. The two handle pools work in parallel, and the working status of the two handle pools can be exchanged with each other, which can realize timely clearing of unused file handles. In this way, the capacity of each handle pool does not need to be too large. On the one hand, the search efficiency of the target file can be guaranteed, and on the other hand, the storage space occupied by all the handle pools can be further saved.

在一些可选的实现方式中，上述根据操作请求信息，从目标位置查找与目标文件对应的目标句柄，可以包括如下第一步和第二步。In some optional implementation manners, searching for the target handle corresponding to the target file from the target location according to the operation request information may include the following first and second steps.

第一步，若操作请求信息与活跃文件的文件描述信息相适配，则将活跃文件的文件句柄确定为目标句柄。In the first step, if the operation request information matches the file description information of the active file, the file handle of the active file is determined as the target handle.

其中，上述活跃文件的文件描述信息通常是用于对活跃文件进行描述的信息。实践中，活跃文件的文件描述信息通常包括活跃文件的文件标识。Wherein, the above-mentioned file description information of the active file is generally information used to describe the active file. In practice, the file description information of the active file usually includes the file identifier of the active file.

这里，上述执行主体可以采用操作请求信息所包括的目标文件的文件标识，与活跃文件的文件描述信息所包括的文件标识进行比较，若二者一致，则可以认为活跃文件即为所需查找的目标文件。此时，可以将活跃文件对应的文件句柄确定为上述目标句柄。Here, the above-mentioned execution subject can use the file identification of the target file included in the operation request information to compare with the file identification included in the file description information of the active file. If the two are consistent, it can be considered that the active file is the one to be searched. target document. At this point, the file handle corresponding to the active file may be determined as the above-mentioned target handle.

第二步，若操作请求信息与活跃文件的文件描述信息不适配，则从句柄池组中查找与操作请求信息相匹配的文件句柄，以及将查找到的文件句柄确定为目标句柄。In the second step, if the operation request information does not match the file description information of the active file, search for a file handle matching the operation request information from the handle pool group, and determine the found file handle as the target handle.

这里，在操作请求信息与活跃文件的文件描述信息不适配时，表明所需查找的目标文件并非当前的活跃文件。此时，上述执行主体可以采用操作请求信息所包括的文件标识，继续从句柄池组中，查找对应文件标识与目标文件的文件标识相同的文件句柄。在从句柄池组中查找到对应文件标识与目标文件的文件标识相同的文件句柄的情况下，可以将查找到的文件句柄确定为上述目标句柄。Here, when the operation request information does not match the file description information of the active file, it indicates that the target file to be searched is not the current active file. At this time, the above-mentioned execution subject may use the file identifier included in the operation request information to continue to search for a file handle whose corresponding file identifier is the same as the file identifier of the target file from the handle pool group. In the case that a file handle whose corresponding file ID is the same as that of the target file is found from the handle pool group, the found file handle may be determined as the above-mentioned target handle.

本实现方式中，优先从活跃文件处查找目标句柄，在活跃文件的文件句柄不为目标句柄的情况下，再从句柄池组中查找目标句柄，可以实现从多个位置有序查找，有助于提高查找效率。In this implementation, the target handle is first searched from the active file, and when the file handle of the active file is not the target handle, the target handle is searched from the handle pool group, which can realize orderly search from multiple locations, which is helpful to improve search efficiency.

在一些可选的实现方式中，上述第二步中，从句柄池组中查找与操作请求信息相匹配的文件句柄，以及将查找到的文件句柄确定为目标句柄，可以包括：从处于活跃状态的句柄池中查找目标句柄，和/或若处于活跃状态的句柄池中不存在目标句柄，则从处于空闲状态的句柄池中查找目标句柄。In some optional implementations, in the above second step, searching for a file handle matching the operation request information from the handle pool group, and determining the found file handle as the target handle may include: Look up the target handle in the handle pool of the active state, and/or if the target handle does not exist in the handle pool in the active state, look for the target handle in the handle pool in the idle state.

这里，句柄池组中包括工作状态相异的两个句柄池。此时，上述执行主体可以仅从处于活跃状态的句柄池中查找目标句柄。也可以先从处于活跃状态的句柄池中查找目标句柄。在处于活跃状态的句柄池中不存在该目标句柄的情况下，再从处于空闲状态的句柄池中查找目标句柄。Here, the handle pool group includes two handle pools with different working states. At this point, the above execution subject may only search for the target handle from the handle pool in an active state. Alternatively, the target handle can be searched first from the active handle pool. If the target handle does not exist in the handle pool in the active state, look for the target handle in the handle pool in the idle state.

在仅从处于活跃状态的句柄池中查找目标句柄的情况下，若处于活跃状态的句柄池中不存在目标句柄，则上述执行主体可以认为目标位置不存在与目标文件对应的目标句柄。此时，上述执行主体可以通过遍历区块链上存储的区块数据的方式，查找得到目标文件及用于存储目标文件的文件地址，以及针对查找到的该目标文件创建目标句柄。由于处于空闲状态的句柄池负责及时清除长期未被使用的文件句柄，且处于活跃状态的句柄池负责新的文件句柄的添加及引用等。因此，仅从处于活跃状态的句柄池中查找目标句柄，两个句柄池分工无交叉，可以简化操作，保障两个句柄池高效地进行并行工作。In the case of searching for the target handle only from the handle pool in the active state, if the target handle does not exist in the handle pool in the active state, the execution subject may consider that there is no target handle corresponding to the target file in the target location. At this point, the execution subject can find the target file and the file address used to store the target file by traversing the block data stored on the blockchain, and create a target handle for the found target file. Because the handle pool in the idle state is responsible for clearing the file handles that have not been used for a long time in time, and the handle pool in the active state is responsible for adding and referencing new file handles. Therefore, the target handle is only searched from the handle pool in the active state, and the division of labor between the two handle pools does not overlap, which can simplify operations and ensure that the two handle pools can work efficiently in parallel.

需要指出的是，由于目标句柄可能同时存在于多个句柄池中的情况，优先从处于活跃状态的句柄池中查找的方式，可以实现更加高效有序地进行信息查找，有助于进一步提高查找效率。另外，由于处于空闲状态的句柄池的主要职责在于及时对不使用的文件句柄进行清理，优先从处于活跃状态的句柄池中查找的方式，可以保障两个句柄池更加高效地进行并行工作。It should be pointed out that since the target handle may exist in multiple handle pools at the same time, the method of searching from the handle pool in the active state can be used to search for information more efficiently and orderly, which helps to further improve the search process. efficiency. In addition, since the main responsibility of the handle pool in the idle state is to clean up unused file handles in a timely manner, the method of searching from the handle pool in the active state first can ensure that the two handle pools can work in parallel more efficiently.

在一些实施例的可选的实现方式中，若句柄池组中包括工作状态相异的两个句柄池，则上述执行主体在采用操作请求信息，从目标位置查找与目标文件对应的目标句柄的过程中，通常遵循如下查找顺序：首先，从活跃文件的文件句柄处查找目标句柄。之后，若活跃文件的文件句柄不为目标句柄，则从处于活跃状态的句柄池中查找目标句柄。最后，若处于活跃状态的句柄池中不存在目标句柄，则从处于空闲状态的句柄池中查找目标句柄。In an optional implementation of some embodiments, if the handle pool group includes two handle pools with different working states, the execution subject uses the operation request information to search for the target handle corresponding to the target file from the target location During the process, the following search order is usually followed: First, the target handle is searched from the file handle of the active file. Afterwards, if the file handle of the active file is not the target handle, the target handle is searched from the active handle pool. Finally, if the target handle does not exist in the handle pool in the active state, the target handle is searched from the handle pool in the idle state.

另外，在各个目标位置均不存在上述目标句柄的情况下，上述执行主体可以通过遍历区块链上存储的区块数据的方式，查找得到目标文件及用于存储目标文件的文件地址。此时，上述执行主体还可以针对查找到的该目标文件创建目标句柄，并存入处于活跃状态的句柄池中。这样，在下一次需要对该目标文件进行操作时，可以通过该目标文件对应的文件句柄快速查找到该目标文件，从而提高区块链数据处理效率。In addition, in the case that the above-mentioned target handle does not exist in each target location, the above-mentioned execution subject can find the target file and the file address used to store the target file by traversing the block data stored on the blockchain. At this time, the above-mentioned execution subject may also create a target handle for the found target file, and store it in an active handle pool. In this way, when the target file needs to be operated next time, the target file can be quickly found through the file handle corresponding to the target file, thereby improving the blockchain data processing efficiency.

在各个实施例的可选的实现方式中，若句柄池组中包括工作状态相异的两个句柄池，且各句柄池中的文件句柄包括文件标识、文件地址和动态引用次数，则上述区块链数据处理方法还可以包括如下步骤一和步骤二。In an optional implementation of each embodiment, if the handle pool group includes two handle pools with different working states, and the file handles in each handle pool include file identifiers, file addresses, and dynamic reference times, the above-mentioned area The block chain data processing method may also include the following steps 1 and 2.

步骤一，若从处于活跃状态的句柄池中查找到目标句柄，则增加处于活跃状态的句柄池中的相应文件句柄的动态引用次数。Step 1: If the target handle is found from the handle pool in the active state, increase the number of dynamic references of the corresponding file handle in the handle pool in the active state.

这里，若目标句柄存在于处于活跃状态的句柄池中，则在查找到该目标句柄时，上述执行主体可以按照预先设定的增加方式，增加处于活跃状态的句柄池中的相应文件句柄的动态引用次数。其中，上述增加方式可以为每次增加1，也可以是每次增加2，还可以是其它增加方式。实践中，通常是每次增加1。Here, if the target handle exists in the handle pool in the active state, when the target handle is found, the execution subject can increase the dynamics of the corresponding file handle in the handle pool in the active state according to the preset increase method. Citations. Wherein, the above-mentioned increasing manner may be 1 each time, or 2 each time, or other increasing manners. In practice, it is usually increased by 1 each time.

举例来说，若目标句柄存在于处于活跃状态的句柄池A中，且具体为句柄池A中的文件句柄1，那么，在查找得到该目标句柄时，可以对句柄池A中的文件句柄1的动态引用次数增加1。For example, if the target handle exists in handle pool A that is active, and is specifically file handle 1 in handle pool A, then, when the target handle is found, the file handle 1 in handle pool A can be The dynamic reference count of is increased by 1.

步骤二，若处于活跃状态的句柄池中不存在目标句柄，则根据操作请求信息创建目标句柄，以及将创建的目标句柄存入处于活跃状态的句柄池中。Step 2: If the target handle does not exist in the handle pool in the active state, create a target handle according to the operation request information, and store the created target handle in the handle pool in the active state.

这里，在仅从处于活跃状态的句柄池中查找目标句柄的情况下，若处于活跃状态的句柄池中不存在目标句柄，则上述执行主体可以认为目标位置不存在与目标文件对应的目标句柄。此时，上述执行主体可以通过如下方式创建目标句柄：遍历区块链上存储的区块数据，以查找得到与操作请求信息相匹配的目标文件及用于存储目标文件的文件地址，然后，采用目标文件的文件地址、文件标识和预设引用次数创建得到上述目标句柄。其中，上述预设引用次数通常是预先设定的次数。实践中，上述预设引用次数通常是1。Here, in the case of only looking for the target handle from the handle pool in the active state, if the target handle does not exist in the handle pool in the active state, the execution subject may consider that there is no target handle corresponding to the target file in the target location. At this time, the above execution subject can create the target handle in the following way: traverse the block data stored on the blockchain to find the target file matching the operation request information and the file address used to store the target file, and then use The file address, file identifier and preset reference count of the target file are created to obtain the above target handle. Wherein, the above-mentioned preset number of references is usually a preset number of times. In practice, the above preset number of references is usually 1.

另外，在可以先后从两个句柄池中查找目标句柄的情况下，若目标句柄不存在于处于活跃状态的句柄池中，但存在于处于空闲状态的句柄池中。此时，上述执行主体可以通过如下方式创建目标句柄：从处于空闲状态的句柄池中查找到与操作请求信息相匹配的目标句柄，然后，基于查找到的目标句柄和预设引用次数创建得到上述目标句柄。其中，新创建的上述目标句柄的动态引用次数通常为预设引用次数。In addition, in the case that the target handle can be searched from the two handle pools successively, if the target handle does not exist in the handle pool in the active state, but exists in the handle pool in the idle state. At this point, the above execution subject can create the target handle in the following way: Find the target handle that matches the operation request information from the handle pool in the idle state, and then create the above-mentioned target handle based on the found target handle and the preset number of references target handle. Wherein, the dynamic reference count of the above-mentioned newly created target handle is usually a preset reference count.

需要指出的是，由于处于活跃状态的句柄池的主要职责在于对新的文件句柄进行添加及引用。在目标句柄不存在于处于活跃状态的句柄池，但存在于处于空闲状态的句柄池的情况下，基于从处于空闲状态的句柄池查找到的目标句柄，创建目标句柄并放入处于活跃状态的句柄池中，可以实现及时在处于活跃状态的句柄池中创建目标句柄，可以保障两个句柄池更加高效地进行并行工作。It should be pointed out that the main responsibility of the active handle pool is to add and reference new file handles. If the target handle does not exist in the active handle pool but exists in the idle handle pool, based on the target handle found from the idle handle pool, create the target handle and put it in the active In the handle pool, the target handle can be created in the active handle pool in time, which can ensure that the two handle pools can work in parallel more efficiently.

在一些可选的实现方式中，上述区块链数据处理方法还可以包括如下步骤三和步骤四。In some optional implementation manners, the above block chain data processing method may also include the following steps 3 and 4.

步骤三，在对目标文件执行目标操作之后，根据目标句柄在处于空闲状态的句柄池中的存在情况，减少目标句柄池中的相应文件句柄的动态引用次数。其中，目标句柄池，可以包括处于空闲状态的句柄池和处于活跃状态的句柄池。Step 3: After the target operation is performed on the target file, according to the existence of the target handle in the idle handle pool, the number of dynamic references of the corresponding file handle in the target handle pool is reduced. Wherein, the target handle pool may include a handle pool in an idle state and a handle pool in an active state.

实践中，上述根据目标句柄在处于空闲状态的句柄池中的存在情况，减少目标句柄池中的相应文件句柄的动态引用次数，包括：若检测到处于空闲状态的句柄池中还存在目标句柄，则减少处于空闲状态的句柄池中的相应文件句柄的动态引用次数。若检测到处于空闲状态的句柄池中不存在目标句柄，则减少处于活跃状态的句柄池中的相应文件句柄的动态引用次数。In practice, according to the existence of the target handle in the handle pool in the idle state, the number of dynamic references of the corresponding file handle in the target handle pool is reduced, including: if it is detected that the target handle still exists in the handle pool in the idle state, Then reduce the number of dynamic references of the corresponding file handle in the handle pool in the idle state. If it is detected that the target handle does not exist in the handle pool in the idle state, then reduce the number of dynamic references of the corresponding file handle in the handle pool in the active state.

这里，在对目标文件执行目标操作之后，上述执行主体可以判断处于空闲状态的句柄池中是否还存在该目标句柄，若存在，则上述执行主体可以对处于空闲状态的句柄池中的相应文件句柄的动态引用次数减少。若不存，则上述执行主体可以减少处于活跃状态的句柄池中的相应文件句柄的动态引用次数。这样，可以实现对两个句柄池进行及时有效管理。在节约存储空间的同时，保障两个句柄池更加高效地进行并行工作。Here, after executing the target operation on the target file, the above-mentioned execution subject can judge whether the target handle still exists in the handle pool in the idle state, and if it exists, the above-mentioned execution subject can check the corresponding file handle in the handle pool in the idle state. The number of dynamic citations for is reduced. If not, the above-mentioned execution subject may reduce the number of dynamic references of the corresponding file handle in the handle pool in an active state. In this way, timely and effective management of the two handle pools can be realized. While saving storage space, it ensures that the two handle pools can work in parallel more efficiently.

需要指出的是，对文件句柄的动态引用次数进行增加的方式，可以与对文件句柄的动态引用次数进行减少的方式相对应，也可以不相对应。It should be pointed out that the manner of increasing the dynamic reference count of the file handle may or may not correspond to the manner of decreasing the dynamic reference count of the file handle.

举例来说，可以在查找到目标句柄时，对处于活跃状态的句柄池中的对应文件句柄的动态引用次数增加1，以及在对目标文件操作结束时，对处于空闲状态的句柄池中的对应文件句柄的动态引用次数减少1。也可以在查找到目标句柄时，对处于活跃状态的句柄池中的对应文件句柄的动态引用次数增加2，以及在对目标文件操作结束时，对处于空闲状态的句柄池中的对应文件句柄的动态引用次数减少1。实践中，对文件句柄的动态引用次数进行增加的方式，通常与对文件句柄的动态引用次数进行减少的方式相对应，且通常增加和减少的数量都为1，这样可以比较明确地获悉，每个句柄文件当前同时被调用的次数。For example, when the target handle is found, the number of dynamic references to the corresponding file handle in the handle pool in the active state is increased by 1, and when the operation on the target file ends, the number of references to the corresponding file handle in the handle pool in the idle state is increased by 1. The dynamic reference count of the file handle is reduced by 1. It is also possible to increase the number of dynamic references to the corresponding file handle in the handle pool in the active state by 2 when the target handle is found, and to increase the number of dynamic references to the corresponding file handle in the handle pool in the idle state when the operation on the target file ends. The number of dynamic references is reduced by 1. In practice, the method of increasing the number of dynamic references to the file handle usually corresponds to the method of reducing the number of dynamic references to the file handle, and usually the number of increases and decreases is 1, so that it can be clearly learned that every The number of times that handle files are currently called at the same time.

实践中，在对目标文件执行目标操作之后，在对目标句柄池中的相应文件句柄的动态引用次数减少的过程中，若检测到两个句柄池中均不存在目标句柄，此时，上述执行主体可以发出报错信息。该报错信息可以提示找不到待归还的目标句柄。及时对程序故障进行报错，可以使得工作人员及时发现问题并处理。In practice, after the target operation is performed on the target file, in the process of reducing the number of dynamic references to the corresponding file handle in the target handle pool, if it is detected that the target handle does not exist in the two handle pools, at this time, the above execution The subject can issue error messages. The error message may indicate that the target handle to be returned cannot be found. Reporting errors to program failures in a timely manner can enable staff to discover and deal with problems in a timely manner.

步骤四，将处于空闲状态的句柄池中的、对应动态引用次数为零的文件句柄删除。Step 4, delete the file handle corresponding to the dynamic reference count of zero in the handle pool in the idle state.

这里，上述执行主体可以及时将处于空闲状态的句柄池中的不使用的文件句柄清除。可以节约存储空间。Here, the above-mentioned execution subject may clear unused file handles in the handle pool in an idle state in time. Can save storage space.

需要指出的是，由于处于空闲状态的句柄池的主要职责在于及时对不使用的文件句柄进行清理。在目标句柄还存在于处于空闲状态的句柄池的情况下，在对目标文件执行完目标操作时，减少处于空闲状态的句柄池中的相应文件句柄的动态引用次数，有助于实现更快地从处于空闲状态的句柄池中减少重复文件句柄的动态引用次数，从而及时清除掉上述重复文件句柄，既可以节约存储空间，还可以保障两个句柄池更加高效地进行并行工作。其中，上述重复文件句柄，通常是指同时存在于处于空闲状态的句柄池和处于活跃状态的句柄池中的文件句柄。It should be pointed out that the main responsibility of the handle pool in the idle state is to clean up unused file handles in a timely manner. In the case that the target handle still exists in the handle pool in the idle state, when the target operation is performed on the target file, reducing the number of dynamic references of the corresponding file handle in the handle pool in the idle state helps to achieve faster Reduce the number of dynamic references of duplicate file handles from the handle pool in the idle state, so as to clear the above-mentioned duplicate file handles in time, which can not only save storage space, but also ensure that the two handle pools can work in parallel more efficiently. Wherein, the above-mentioned repeated file handle generally refers to a file handle that exists in both the handle pool in the idle state and the handle pool in the active state.

在一些实施例的可选的实现方式中，若句柄池组中包括工作状态相异的两个句柄池，且各句柄池中的文件句柄包括文件标识、文件地址和动态引用次数，则在根据操作请求信息，从目标位置查找与目标文件对应的目标句柄之后，上述区块链数据处理方法还可以包括如下步骤。In an optional implementation of some embodiments, if the handle pool group includes two handle pools with different working states, and the file handles in each handle pool include file identifiers, file addresses, and dynamic reference times, then according to After the operation request information is searched for the target handle corresponding to the target file from the target location, the above block chain data processing method may further include the following steps.

首先，若目标位置不存在与目标文件对应的目标句柄，则遍历目标区块链上存储的区块数据，直至查询得到与操作请求信息相匹配的目标文件。First, if there is no target handle corresponding to the target file at the target location, the block data stored on the target blockchain is traversed until the target file matching the operation request information is queried.

这里，在各个目标位置均不存在上述目标句柄的情况下，上述执行主体可以通过遍历区块链上存储的区块数据的方式，查找得到目标文件及用于存储目标文件的文件地址。之后，可以对目标文件执行目标操作。Here, in the case that the above-mentioned target handle does not exist in each target location, the above-mentioned execution subject can find the target file and the file address for storing the target file by traversing the block data stored on the blockchain. Afterwards, target operations can be performed on the target file.

然后，将查询得到的目标文件的文件地址确定为目标地址，以及根据目标文件的文件标识、目标地址和预设引用次数，创建与目标文件对应的目标句柄，以及将目标句柄存入处于活跃状态的句柄池。Then, determine the file address of the target file obtained from the query as the target address, and create a target handle corresponding to the target file according to the file identifier, target address and preset reference times of the target file, and store the target handle in the active state handle pool.

其中，上述预设引用次数通常是预先设定的次数。实践中，上述预设引用次数通常是1。Wherein, the above-mentioned preset number of references is usually a preset number of times. In practice, the above preset number of references is usually 1.

这里，在从区块链上遍历查找得到目标文件及目标文件的文件地址时，上述执行主体可以采用目标文件的文件标识、目标文件的文件地址和预设引用次数，组合生成与目标文件对应的上述目标句柄。之后，可以将目标句柄存入处于活跃状态的句柄池中。这样，在下一次需要对该目标文件进行操作时，可以通过该目标文件对应的文件句柄快速查找到该目标文件，从而提高区块链数据处理效率。Here, when traversing the block chain to obtain the target file and the file address of the target file, the above-mentioned execution subject can use the file identification of the target file, the file address of the target file and the preset number of references to generate a combination of The above target handle. Afterwards, the target handle can be stored in the pool of active handles. In this way, when the target file needs to be operated next time, the target file can be quickly found through the file handle corresponding to the target file, thereby improving the blockchain data processing efficiency.

在一些实施例的可选的实现方式中，上述区块链数据处理方法还可以包括如下步骤：若句柄池组中包括工作状态相异的两个句柄池，则在预设触发条件被触发时，对两个句柄池的工作状态进行调换。In an optional implementation of some embodiments, the above blockchain data processing method may also include the following steps: if the handle pool group includes two handle pools with different working states, when the preset trigger condition is triggered , to exchange the working status of the two handle pools.

其中，预设触发条件包括以下至少一项：到达预设调换周期、处于活跃状态的句柄池中的文件句柄数目超过预设数目阈值。其中，上述预设触发条件通常是预先设定的用于触发两个句柄池调换工作状态的条件。上述预设调换周期通常是预先设定的周期值，比如，可以为5分钟。上述预设数目阈值通常是预先设定的数目值，比如，可以为50个。需要指出的是，上述预设触发条件中，还可以包括除上述所列举的两个条件之外的其它条件。Wherein, the preset triggering conditions include at least one of the following: reaching a preset exchange period, and the number of file handles in the active handle pool exceeding a preset number threshold. Wherein, the above-mentioned preset triggering condition is usually a preset condition for triggering the switching of the working states of the two handle pools. The aforementioned preset exchange cycle is usually a preset cycle value, for example, it may be 5 minutes. The aforementioned preset number threshold is usually a preset number value, for example, it may be 50. It should be noted that the above preset trigger conditions may also include other conditions besides the two conditions listed above.

这里，上述执行主体可以在预设触发条件被触发的情况下，及时对两个句柄池的工作状态进行调换。具体地，将原本处于活跃状态的句柄池切换为处于空闲状态，以及将原本处于空闲状态的句柄池切换为处于活跃状态。这样可以实现及时有效地对处于空闲状态的句柄池中的未使用的文件句柄进行清除，可以进一步节约存储空间。Here, the above-mentioned execution subject can switch the working states of the two handle pools in time when the preset trigger condition is triggered. Specifically, switch the handle pool that was originally in the active state to be in the idle state, and switch the handle pool that was originally in the idle state to be in the active state. In this way, unused file handles in the handle pool in the idle state can be cleared in a timely and effective manner, which can further save storage space.

另外，两个句柄池并行工作，且两个句柄池的工作状态可以相互调换，一个保障数据处理任务有序进行，另一个保障及时清除未使用的文件句柄。这样，每个句柄池的容量无需太大，一方面可以保障对目标文件的查找效率，另一方面可以进一步节省所有句柄池所占的存储空间。In addition, the two handle pools work in parallel, and the working status of the two handle pools can be exchanged with each other. One ensures that data processing tasks are carried out in an orderly manner, and the other ensures that unused file handles are cleared in time. In this way, the capacity of each handle pool does not need to be too large. On the one hand, the search efficiency of the target file can be guaranteed, and on the other hand, the storage space occupied by all the handle pools can be further saved.

在一些实施例的可选的实现方式中，上述区块链数据处理方法还可以包括如下步骤：在活跃文件被写满时，上链存储活跃文件以及将活跃文件的文件句柄写入处于活跃状态的句柄池中，创建对应有文件句柄的新的文件，将新的文件切换为活跃文件。In an optional implementation of some embodiments, the above block chain data processing method may also include the following steps: when the active file is full, store the active file on the chain and write the file handle of the active file into the active state In the handle pool, create a new file corresponding to the file handle, and switch the new file to the active file.

其中，上述活跃文件，通常是区块链节点中尚未上链存储的处于被写入状态的文件。活跃文件中可以被先后写入多条数据。在活跃文件被写满时，上述执行主体可以将活跃文件的文件句柄写入处于活跃状态的句柄池中。Among them, the above-mentioned active files are usually files in the state of being written that have not been stored on the chain in the blockchain node. Multiple pieces of data can be written successively in the active file. When the active file is full, the execution subject may write the file handle of the active file into the handle pool in an active state.

实际应用中，活跃文件的文件句柄写入处于活跃状态的句柄池时，新添加至处于活跃状态的句柄池中的文件句柄可以包括该活跃文件的文件名、该活跃文件被存储在区块链上的文件地址、初始引用次数。其中，初始引用次数通常是预先设定的次数值。实际应用中，初始引用次数通常为0。In practical applications, when the file handle of the active file is written into the handle pool in the active state, the file handle newly added to the handle pool in the active state can include the file name of the active file, the active file is stored in the blockchain The file address and initial reference count on the . Wherein, the initial number of references is usually a preset number of times. In practical applications, the initial reference count is usually 0.

需要指出的是，在当前的活跃文件被写满以及被上链存储时，上述执行主体可以生成用于写入数据的新的活跃文件，以及给新的活跃文件创建对应的文件句柄。It should be pointed out that when the current active file is full and stored on the chain, the above execution subject can generate a new active file for writing data, and create a corresponding file handle for the new active file.

继续参考图3，为本申请实施例提供的一种区块链数据处理方法的流程示意图。如图3所示的区块链数据处理方法，可以包括如下步骤301至步骤313。需要指出的是，上述步骤301至步骤313的执行主体为上述目标区块链，具体可以为上述目标区块链上的各个区块链节点。实际应用中，每个区块链节点可以实现成终端也可以实现成服务器。Continue to refer to FIG. 3 , which is a schematic flowchart of a blockchain data processing method provided by the embodiment of the present application. The blockchain data processing method shown in FIG. 3 may include the followingsteps 301 to 313. It should be pointed out that the execution subject of the above-mentionedsteps 301 to 313 is the above-mentioned target blockchain, specifically, each blockchain node on the above-mentioned target blockchain. In practical applications, each blockchain node can be implemented as a terminal or as a server.

步骤301，接收文件读取请求。Step 301, receiving a file reading request.

这里，上述文件读取请求与前述操作请求信息概念相同。这里，文件读取请求指示对目标文件执行文件读取操作。这里，目标操作为文件读取操作，且目标文件为待读取的文件。Here, the aforementioned file read request has the same concept as the aforementioned operation request information. Here, the file read request indicates to perform a file read operation on a target file. Here, the target operation is a file reading operation, and the target file is a file to be read.

步骤302，校验文件读取请求是否合法。Step 302, checking whether the file reading request is legal.

在文件读取请求合法的情况下，可以执行步骤303，反之，执行步骤313。In the case that the file reading request is legal, step 303 may be performed; otherwise, step 313 may be performed.

步骤303，判断是否在活跃文件中找到句柄。Step 303, judging whether the handle is found in the active file.

这里，可以采用文件读取请求所包括的文件名，与活跃文件的文件名进行比较，实现判断活跃文件是否为目标文件。若活跃文件为目标文件，则可以将活跃文件的文件句柄确定为目标文件的文件句柄。为了便于描述，可以将目标文件的文件句柄记作目标句柄。在活跃文件即为目标文件时，可以认为在活跃文件中找到句柄，也即是在活跃文件中找到目标句柄。Here, the file name included in the file read request may be used and compared with the file name of the active file to realize whether the active file is the target file. If the active file is the target file, the file handle of the active file may be determined as the file handle of the target file. For the convenience of description, the file handle of the target file can be recorded as the target handle. When the active file is the target file, it can be considered that the handle is found in the active file, that is, the target handle is found in the active file.

之后，在活跃文件中找到目标句柄的情况下，可以执行步骤306。否则，在活跃文件中不存在目标句柄的情况下，可以执行步骤304。Afterwards, in case the target handle is found in the active file,step 306 may be performed. Otherwise, if the target handle does not exist in the active file,step 304 may be executed.

需要指出的是，步骤301-步骤313所提及的要查找的句柄，通常指目标句柄，也即是目标文件对应的文件句柄。It should be pointed out that the handle to be searched mentioned insteps 301 to 313 usually refers to the target handle, that is, the file handle corresponding to the target file.

步骤304，判断是否在活跃句柄池中找到句柄。Step 304, judging whether the handle is found in the active handle pool.

其中，上述活跃句柄池为前述处于活跃状态的句柄池。Wherein, the above-mentioned active handle pool is the aforementioned handle pool in an active state.

这里，在活跃文件中不存在目标句柄的情况下，可以采用文件读取请求所包括的文件名，从活跃句柄池中查找与该文件名对应的文件句柄。若查找到，则可以确定在活跃句柄池中找到句柄，也即是，在活跃句柄池中找到目标句柄。Here, if the target handle does not exist in the active file, the file name included in the file read request may be used to search for a file handle corresponding to the file name from the active handle pool. If found, it can be determined that the handle is found in the active handle pool, that is, the target handle is found in the active handle pool.

之后，在活跃句柄池中找到目标句柄的情况下，可以执行步骤307。否则，在活跃句柄池中不存在目标句柄的情况下，可以执行步骤305。Afterwards, if the target handle is found in the active handle pool, step 307 may be executed. Otherwise, if there is no target handle in the active handle pool, step 305 may be executed.

步骤305，在活跃句柄池中创建读取请求对应的句柄。Step 305, create a handle corresponding to the read request in the active handle pool.

这里，在活跃句柄池中不存在目标句柄的情况下，可以继续查找空闲句柄池中是否存在目标句柄。若存在，则可以根据空闲句柄池中的目标句柄，在活跃句柄池中创建该目标句柄。若不存在，则可以通过遍历区块链上存储的区块数据的方式，查找得到目标文件及用于存储目标文件的文件地址，以及针对查找到的该目标文件创建目标句柄，并存入处于活跃状态的句柄池中。其中，上述空闲句柄池为前述处于空闲状态的句柄池。Here, in the case that the target handle does not exist in the active handle pool, it may continue to search for whether the target handle exists in the free handle pool. If it exists, the target handle can be created in the active handle pool according to the target handle in the free handle pool. If it does not exist, you can find the target file and the file address used to store the target file by traversing the block data stored on the blockchain, and create a target handle for the found target file, and store it in the Active handle pool. Wherein, the above-mentioned free handle pool is the aforementioned handle pool in an idle state.

步骤306，根据获取到的句柄进行文件读取操作。Step 306, perform a file reading operation according to the obtained handle.

这里，可以根据目标句柄指向的目标文件的文件地址，查找得到目标文件，以及对目标文件执行文件读取操作。Here, the target file can be found according to the file address of the target file pointed to by the target handle, and a file read operation can be performed on the target file.

步骤307，句柄池中的句柄引用计数+1。Instep 307, the handle reference count in the handle pool is increased by 1.

这里，上述引用计数与前述动态引用次数概念相同。在活跃句柄池中找到目标句柄的情况下，可以对活跃句柄池中的相应文件句柄的动态引用次数加1。Here, the aforementioned reference count has the same concept as the aforementioned dynamic reference count. If the target handle is found in the active handle pool, 1 may be added to the dynamic reference count of the corresponding file handle in the active handle pool.

步骤308，文件读取操作完成。Step 308, the file reading operation is completed.

步骤309，在读取请求对应的句柄来自句柄池时，进入句柄池操作。Step 309, when the handle corresponding to the read request comes from the handle pool, enter the handle pool operation.

这里，在目标句柄来自活跃句柄池或者是空闲句柄池的情况下，上述执行主体可以继续执行步骤310-步骤312。Here, in the case that the target handle is from the active handle pool or the idle handle pool, the execution subject may continue to execute steps 310 - 312 .

另外，在目标句柄来自活跃文件的情况下，可以执行步骤313。In addition,step 313 can be performed in the case that the target handle is from the active file.

步骤310，判断是否能在空闲句柄池中找到句柄。Step 310, judging whether the handle can be found in the free handle pool.

这里，若空闲句柄池中存在目标句柄，则可以对空闲句柄池执行步骤312。Here, if the target handle exists in the free handle pool, step 312 may be performed on the free handle pool.

若空闲句柄池中不存在目标句柄，则可以执行步骤311。If there is no target handle in the free handle pool, step 311 may be executed.

步骤311，在活跃句柄池中找到句柄。Step 311, find the handle in the active handle pool.

在读取请求对应的目标句柄来自句柄池，且目标句柄不存在于空闲句柄池的情况下，说明目标句柄存在于活跃句柄池。此时，可以在活跃句柄池中找到目标句柄。在活跃句柄池中找到目标句柄的情况下，可以对活跃句柄池执行步骤312。If the target handle corresponding to the read request comes from the handle pool, and the target handle does not exist in the free handle pool, it means that the target handle exists in the active handle pool. At this point, the target handle can be found in the active handle pool. In case the target handle is found in the active handle pool, step 312 may be performed on the active handle pool.

步骤312，对句柄池中的句柄引用计数-1。Step 312, the handle reference count in the handle pool is -1.

这里，在读取请求对应的目标句柄来自句柄池的情况下，若目标句柄来自空闲句柄池，则对空闲句柄池中的相应文件句柄的动态引用次数减1。Here, in the case that the target handle corresponding to the read request comes from the handle pool, if the target handle comes from the free handle pool, the number of dynamic references to the corresponding file handle in the free handle pool is decremented by 1.

在读取请求对应的目标句柄来自句柄池的情况下，若目标句柄来自活跃句柄池，则对活跃句柄池中的相应文件句柄的动态引用次数减1。In the case that the target handle corresponding to the read request comes from the handle pool, if the target handle comes from the active handle pool, the number of dynamic references to the corresponding file handle in the active handle pool is decremented by 1.

步骤313，结束执行上述区块链数据处理方法。Step 313, end execution of the above blockchain data processing method.

本实施例提供的方法，由于文件句柄通常可以指向相对应的文件的文件地址，因此，从活跃文件或者是句柄池组查找与目标文件对应的目标句柄，从而通过目标句柄快速查找到目标文件，可以实现快速准确地查找到需要被操作的目标文件，有助于提高对区块链数据的处理效率。In the method provided by this embodiment, since the file handle can usually point to the file address of the corresponding file, the target handle corresponding to the target file is searched from the active file or the handle pool group, thereby quickly finding the target file through the target handle, It can quickly and accurately find the target file that needs to be operated, which helps to improve the processing efficiency of blockchain data.
