If the requirement comes up for the other in future, we can go for that too. For now we stick to the former. > Also are we going to support Cassandra clusters created through WSO2 > Cassandra versions or is it both WSO2 and external Cassandra clusters? > We already support clusters created by WSO2 Cassandra versions.

That's because we don't have a proper way to infer environments without passing them to API, as we still don't have a standard convention to represent environments in our platform. However data access APIs will not change due to this.
