Any changes needed in fabric if new nodes are added to Cassandra cluster? #960

Closed smokyMount closed 11 months ago

smokyMount commented 11 months ago

Hi,

In prod, we have an 18-node Cassandra cluster (9 in one DC and 9 in remote) out of which 3 nodes from first DC (the seed nodes) are listed as HOSTS in the config.ini file. They have added 33 new nodes to each DC. Do we need to make any changes to our configurations like adding more nodes to HOSTS param, changing replication options, consistency level, etc.?

Thanks, Hardik

Hardik, I know I’m not answering your question, I’ll leave that to the tech team, Can you share a bit more info ? What is the project they are adding 66 nodes to Cassandra ? Why are they adding so many nodes ?

Hi Hardik, Adding new Cassandra nodes shouldn't impact any configuration changes in Fabric. This is assuming that you have already configured each Fabric DC with its corresponding Cassandra DC.
