DocumentDB Elastic Cluster - Change Streams

Question

I have a DocumentDB Elastic Cluster and I am attempting to enable change streams on it.

I followed the steps provided here: https://docs.aws.amazon.com/documentdb/latest/developerguide/change_streams.html

But I receive the following error when attempting to execute the adminCommand:

`Unknown admin command modifyChangeStreams`

Are change streams supported on Elastic Clusters? If so, what am I doing wrong?

Answer

Amazon DocumentDB clusters with auto-scaling enabled, including DocumentDB Elastic Clusters, do not currently support change streams. This could be why you're getting an error when attempting to run the admin command modifyChangeStreams.

You could use a non-elastic Amazon DocumentDB cluster or disable auto scaling on your Elastic Cluster if you want to use change streams. You could also use another database service that supports change streams, such as MongoDB Atlas or self-managed MongoDB.
