I have Cassandra cluster where I already configured paths to keystore and truststore. In case I reissued keystore and truststore - I need to restart Cassandra service on each node.

My question is - if it is possible to dynamically reload these key materials without need to restart the nodes?

CodePudding user response：

It depends on the Cassandra version. Starting with Cassandra 4 it can automatically reload trust & key stores, or you can force reload with nodetool reloadssl.

In earlier versions you need to do rolling restart of the cluster.
