本发明涉及计算机技术领域，具体说是一种区块链大数据库的秒级心跳同步方法。The invention relates to the field of computer technology, in particular to a second-level heartbeat synchronization method for a large blockchain database.
背景技术Background technique
在区块链系统中，在数据库服务器提供服务时，通常需要部署多个独立的大数据服务器以同步的方式协同工作，确保资料的准确性、可靠性和不能被修改。因此，在多个数据库中快速同步并存储这些数据成为一项挑战。In the blockchain system, when the database server provides services, it is usually necessary to deploy multiple independent big data servers to work together in a synchronized manner to ensure the accuracy, reliability and inability of the data to be modified. Therefore, quickly synchronizing and storing this data in multiple databases becomes a challenge.
现有技术中，在对多个独立的大数据库进行数据同步时，大多都需要在同步时暂时停止大数据库的服务。在数据库变得非常庞大，且需要加入新的服务器时，需要较长时间的数据传输才能建立同步的数据库，因此每次进行数据库同步可能要停止数十分钟的服务，在完成数据库同步后，才能够开始提供服务，这严重影响了用户的使用。因此，在全球性服务中不能满足用户的期望。In the prior art, when data synchronization is performed on multiple independent large databases, most of the large database services need to be temporarily stopped during synchronization. When the database becomes very large and a new server needs to be added, it takes a long time for data transmission to establish a synchronized database. Therefore, each time the database synchronization is performed, the service may be stopped for tens of minutes. After the database synchronization is completed, the Able to start providing services, which seriously affects the usage of users. Therefore, the user's expectations cannot be met in the global service.
发明内容SUMMARY OF THE INVENTION

一种区块链大数据库的秒级心跳同步方法，包括以下步骤：A second-level heartbeat synchronization method for a large blockchain database, comprising the following steps:
S1，根据现有区块链大数据库中所存储数据的大小与传输速度，定义区块链大数据库中数据同步的同步周期T1＝2n秒，每个区块链大数据库进行同步时只能按同步周期开始进行同步；所述n等于现有区块链大数据库中所存储数据的大小除以传输速度；S1, according to the size and transmission speed of the data stored in the existing large blockchain database, define the synchronization period T1 =2n seconds for data synchronization in the large blockchain database. The synchronization can be started according to the synchronization cycle; the n is equal to the size of the data stored in the existing blockchain large database divided by the transmission speed;
S2，将现有区块链大数据库中的数据定义为file 0；S2, define the data in the existing blockchain database as file 0;
S3，从同步周期2n秒开始将现有区块链大数据库中的file 0写入新加区块链大数据库，到2n-1秒时file 0写入完成，将2n秒～2n-1秒时间内现有区块链大数据库中新增加的数据定义为file 1；S3, from the synchronization period of 2n seconds, the file 0 in the existing blockchain large database is written into the newly added blockchain large database, and the writing of file 0 is completed at 2n-1 seconds, and the 2n seconds to 2 The newly added data in the existing blockchain large database withinn-1 seconds is defined as
S4，从2n-1秒开始将file 1写入新加区块链大数据库中，到2n-2秒时file 1写入完成，将2n-1秒～2n-2秒时间内现有区块链大数据库中新增加的数据定义为file 2；S4, write
S5，以此类推，从21秒开始将现有区块链大数据库的file n-1写入新加区块链大数据库，到20秒时file n-1写入完成，将21秒～20秒时间内现有区块链大数据库中新增加的数据定义为file n；S5, and so on, start from21 seconds to write the file n-1 of the existing blockchain large database into the newly added blockchain large database, and at20 seconds, the file n-1 is written, and the21 The newly added data in the existing blockchain large database within seconds to20 seconds is defined as file n;

S7，当数据同步过程中出现数据传输错误时，从下一个同步周期开始重新进行数据同步；当数据同步过程中没有出现数据传输错误时，则将新加区块链大数据库投入运行；S7, when there is a data transmission error during the data synchronization process, the data synchronization will be restarted from the next synchronization cycle; when there is no data transmission error during the data synchronization process, the newly added blockchain database will be put into operation;

Whether the operating systems are consistent; if they are consistent, directly write file 0 to file n into the file system directory specified by the newly added blockchain database; if they are inconsistent, convert file 0 to file n to conform to the newly added area The operating system of the block chain large database writes the converted file 0 to file n into the file system directory specified by the newly added block chain large database.
在上述技术方案的基础上，步骤S3中，将file 0～file n写入新加区块链大数据库时，需要判断现有区块链大数据库的配置文件类型与新加区块链大数据库的配置文件类型是否一致；如果一致，则直接将file 0～file n写入新加区块链大数据库指定的文件系统目录下；如果不一致，则对新加区块链大数据库的配置文件类型进行转换，将转换后的file 0～file n写入新加区块链大数据库指定的文件系统目录下。On the basis of the above technical solution, in step S3, when writing file 0 to file n into the newly added large blockchain database, it is necessary to determine the configuration file type of the existing large blockchain database and the type of the newly added large blockchain database. Whether the configuration file types are consistent; if they are consistent, directly write file 0 to file n to the file system directory specified by the newly added blockchain database; if they are inconsistent, the configuration file type of the newly added blockchain database After conversion, write the converted file 0 to file n into the file system directory specified by the newly added blockchain database.
