copyBackup(BackupId sourceBackupId, Backup destinationBackup)

public default OperationFuture<Backup,CopyBackupMetadata> copyBackup(BackupId sourceBackupId, Backup destinationBackup)

Creates a copy of backup from an existing backup in Cloud Spanner in the same instance. Any configuration options in the Backup instance will be included in the com.google.spanner.admin.database.v1.CopyBackupRequest.

The expire time of the new backup must be set and be at least 6 hours and at most 366 days after the creation time of the existing backup that is being copied.

updateDatabaseDdl(String instanceId, String databaseId, Iterable<String> statements, String operationId)

public abstract OperationFuture<Void,UpdateDatabaseDdlMetadata> updateDatabaseDdl(String instanceId, String databaseId, Iterable<String> statements, String operationId)

Enqueues the given DDL statements to be applied, in order but not necessarily all at once, to the database schema at some point (or points) in the future. The server checks that the statements are executable (syntactically valid, name tables that exist, etc.) before enqueueing them, but they may still fail upon later execution (e.g., if a statement from another batch of statements is applied first and it conflicts in some way, or if there is some data-related problem like a NULL value in a column to which NOT NULL would be added). If a statement fails, all subsequent statements in the batch are automatically cancelled.

If an operation already exists with the given operation id, the operation will be resumed and the returned future will complete when the original operation finishes. See more information in com.google.cloud.spanner.spi.v1.GapicSpannerRpc#updateDatabaseDdl(String, Iterable, String)

Example to update the database DDL.


 String instanceId = my_instance_id;
 String databaseId = my_database_id;

     databaseId,
     Arrays.asList("ALTER TABLE Albums ADD COLUMN MarketingBudget INT64"),
     null).waitFor();

Parameters
Name	Description
`instanceId`	`String`
`databaseId`	`String`
