batchWrite(request, options)
batchWrite(request?:protos.google.spanner.v1.IBatchWriteRequest,options?:CallOptions):gax.CancellableStream;Batches the supplied mutation groups in a collection of efficient transactions. All mutations in a group are committed atomically. However, mutations across groups can be committed non-atomically in an unspecified order and thus, they must be independent of each other. Partial failure is possible, i.e., some groups may have been committed successfully, while some may have failed. The results of individual batches are streamed into the response as the batches are applied.
BatchWrite requests are not replay protected, meaning that each mutation group may be applied more than once. Replays of non-idempotent mutations may have undesirable effects. For example, replays of an insert mutation may produce an already exists error or if you use generated or commit timestamp-based keys, it may result in additional rows being added to the mutation's table. We recommend structuring your mutation groups to be idempotent to avoid this issue.

commit(request, options)
commit(request?:protos.google.spanner.v1.ICommitRequest,options?:CallOptions):Promise<[protos.google.spanner.v1.ICommitResponse,protos.google.spanner.v1.ICommitRequest|undefined,{}|undefined]>;Commits a transaction. The request includes the mutations to be applied to rows in the database.
Commit might return anABORTED error. This can occur at any time; commonly, the cause is conflicts with concurrent transactions. However, it can also happen for a variety of other reasons. IfCommit returnsABORTED, the caller should re-attempt the transaction from the beginning, re-using the same session.
On very rare occasions,Commit might returnUNKNOWN. This can happen, for example, if the client job experiences a 1+ hour networking failure. At that point, Cloud Spanner has lost track of the transaction outcome and we recommend that you perform another read from the database to see the state of things as they are now.

createSession(request, options)
createSession(request?:protos.google.spanner.v1.ICreateSessionRequest,options?:CallOptions):Promise<[protos.google.spanner.v1.ISession,protos.google.spanner.v1.ICreateSessionRequest|undefined,{}|undefined]>;Creates a new session. A session can be used to perform transactions that read and/or modify data in a Cloud Spanner database. Sessions are meant to be reused for many consecutive transactions.
Sessions can only execute one transaction at a time. To execute multiple concurrent read-write/write-only transactions, create multiple sessions. Note that standalone reads and queries use a transaction internally, and count toward the one transaction limit.
Active sessions use additional server resources, so it is a good idea to delete idle and unneeded sessions. Aside from explicit deletes, Cloud Spanner may delete sessions for which no operations are sent for more than an hour. If a session is deleted, requests to it returnNOT_FOUND.
Idle sessions can be kept alive by sending a trivial SQL query periodically, e.g.,"SELECT 1".

This method allows many statements to be run with lower latency than submitting them sequentially with .
Statements are executed in sequential order. A request can succeed even if a statement fails. TheExecuteBatchDmlResponse.status field in the response provides information about the statement that failed. Clients must inspect this field to determine whether an error occurred.

partitionQuery(request, options)
partitionQuery(request?:protos.google.spanner.v1.IPartitionQueryRequest,options?:CallOptions):Promise<[protos.google.spanner.v1.IPartitionResponse,protos.google.spanner.v1.IPartitionQueryRequest|undefined,{}|undefined]>;Creates a set of partition tokens that can be used to execute a query operation in parallel. Each of the returned partition tokens can be used by to specify a subset of the query result to read. The same session and read-only transaction must be used by the PartitionQueryRequest used to create the partition tokens and the ExecuteSqlRequests that use the partition tokens.
Partition tokens become invalid when the session used to create them is deleted, is idle for too long, begins a new transaction, or becomes too old. When any of these happen, it is not possible to resume the query, and the whole operation must be restarted from the beginning.

partitionRead(request, options)
partitionRead(request?:protos.google.spanner.v1.IPartitionReadRequest,options?:CallOptions):Promise<[protos.google.spanner.v1.IPartitionResponse,protos.google.spanner.v1.IPartitionReadRequest|undefined,{}|undefined]>;Creates a set of partition tokens that can be used to execute a read operation in parallel. Each of the returned partition tokens can be used by to specify a subset of the read result to read. The same session and read-only transaction must be used by the PartitionReadRequest used to create the partition tokens and the ReadRequests that use the partition tokens. There are no ordering guarantees on rows returned among the returned partition tokens, or even within each individual StreamingRead call issued with a partition_token.
Partition tokens become invalid when the session used to create them is deleted, is idle for too long, begins a new transaction, or becomes too old. When any of these happen, it is not possible to resume the read, and the whole operation must be restarted from the beginning.

read(request?:protos.google.spanner.v1.IReadRequest,options?:CallOptions):Promise<[protos.google.spanner.v1.IResultSet,protos.google.spanner.v1.IReadRequest|undefined,{}|undefined]>;Reads rows from the database using key lookups and scans, as a simple key/value style alternative to . This method cannot be used to return a result set larger than 10 MiB; if the read matches more data than that, the read fails with aFAILED_PRECONDITION error.
Reads inside read-write transactions might returnABORTED. If this occurs, the application should restart the transaction from the beginning. SeeTransaction for more details.
Larger result sets can be yielded in streaming fashion by calling instead.
