External Cassandra Cluster Setup Queries
Hello Community,
Has anyone come up with the following scenario?
My client has External Cassandra v3.x D-nodes setup and we have following questions to clarify.
1. What is the mechaism to access Pega portal Cassandra node management operators (e.g. the Stop,repair , Compact, cleanup, De-Commission commands) ? see attached document
2. If we try and enable and configure remote JMX connectivity ourselves, could you confirm whether we are able to use the Pega portal Cassandra node management operators (e.g. the repair , Compact, cleanup command).
Additional Notes extract we've found from Cassandra documentation

The default settings for Cassandra make JMX accessible only from localhost. To enable remote JMX connections, edit cassandra-env.sh (or cassandra-env.ps1 on Windows) to change the LOCAL_JMX setting to yes. Under the standard configuration, when remote JMX connections are enabled, standard JMX authentication is also switched on.

Hi Krishna,
Pega does not support managing an external Cassandra from the Decision Data store landing page. In case of Decision Data Store using an external Cassandra, the nodes will be visible on the landing page. But you will not be able to do any of the operations that you have attached as a part of your screenshot.

Thanks for reply and following question would be on following, can we access those operations in the screenshot attached while Cassandra nodes externally configured in the DDS landing page.
If we try and enable and configure remote JMX connectivity ourselves, could you confirm whether we are able to use the Pega portal Cassandra node management operators (e.g. the repair , Compact, cleanup command).

In case of External Cassandra cluster, you will not be able to use node management operator even if you try and enable remote JMX connectivity yourself.
