Description

The SpannerIO.readChangeStreams Connector uses metadata tables to keep track of its internal state during execution. At the moment, these metadata tables linger after the execution, meaning that users will have to drop them manually.

In this change, we would like to drop them automatically once the job finishes. This should only occur after all partitions have been processed successfully and marked as finished.
