Method: googleapis.spanner.v1.projects.instances.databases.sessions.rollback

Rolls back a transaction, releasing any locks it holds. It's a good idea to call this for any transaction that includes one or more Read or ExecuteSql requests and ultimately decides not to commit. Rollback returns OK if it successfully aborts the transaction, the transaction was already aborted, or the transaction isn't found. Rollback never returns ABORTED.

For more information about retries and long-running operations, see Understand connectors.
