We want to move our clusters to use Vnodes. I know the docs online say we have to create new DC with vnodes and move to new dC and decommission old one. We use DSE for our c* clusters.C* version is 2.0.14
1. Is there any other way to migrate existing nodes to vnodes? 2. What are the known issues with that approach? 3. We have few secondary indexes in the keyspace, will that cause any issues with moving to vnodes? 4. What are the issues encountered after moving to vnodes in PROD 5. anybody recommend Vnodes for Spark nodes. *Approach : Moving to new DC with vnodes enabled*: When I tested it for a keyspace which has secondary indexes, rebuilds on Vnode enabled Datacenter takes days and don't know when it completes or even if it will complete. I tried with 256,32,64 tokens per node but no luck. Please advise.
