Example 38 with Database

use of com.google.spanner.admin.database.v1.Database in project java-spanner by googleapis.

the class GapicSpannerRpc method updateDatabaseDdl.

/**
 * If the update database ddl operation returns an ALREADY_EXISTS error, meaning the operation id
 * used is already in flight, this method will simply resume the original operation. The returned
 * future will be completed when the original operation finishes.
 *
 * <p>This mechanism is necessary, because the update database ddl can be retried. If a retryable
 * failure occurs, the backend has already started processing the update database ddl operation
 * with the given id and the library issues a retry, an ALREADY_EXISTS error will be returned. If
 * we were to bubble this error up, it would be confusing for the caller, who used originally
 * called the method with a new operation id.
