Can we use the same Cassandra cluster for multiple DMS?

Or does each DMS require it's own Cassandra cluster?

Thank you.

Hi Martin,

This is possible.
The main thing is to make sure that every  datamienr cluster uses a unique prefix.

(link to the docs)

Matthijs, Ive,

thanks for the quick and positive answer.
And what if we have 2 DMS that are currently in a Cassandra per Agent setup with the same default “SLDMADB” keyspace and we’d like them to migrate both to the shared Cassandra cluster. Would that work as well? In other words, the local keyspace is not relevant to the cluster keyspace which is chosen during the migration?

Thanks a lot in advance.

Hi Martin,

This shouldn’t be an issue.
When you migrate your data from the standalone setup to the clustered setup, you will have the option to define a prefix for the table on the destination cassandra cluster.
