Amazon DocumentDB

To capture messages from Amazon DocumentDB and convert them into logical change records using Oracle GoldenGate for Distributed Applications and Analytics (GG for DAA), you can utilize MongoDB Extract.

There are several key distinctions between MongoDB capture and Amazon DocumentDB capture:

• Amazon DocumentDB does not support Bidirectional Replication.

• Unlike MongoDB, Amazon DocumentDB does not have an operations log (oplog). To read events in Amazon DocumentDB, you must explicitly enable change streams feature for a specific collection by using the add trandata feature.

• Change streams in Amazon DocumentDB are retained for a default period of 3 hours after the event is recorded. This retention can be extended up to a maximum of 7 days by modifying the change_stream_log_retention_duration parameter.

Note:

• For more information, see MongoDB as a source.
