Hello cassandra folks. So I want to ask how to migrate a keyspace in production to another smaller cluster without have a downtime service.
So I was thinking that I dont want to use sstableloader and paid for the compactions and streaming. I want actually to use the procedure when both clusters have the same numbers of nodes so I just need to make sure to have the same token range repartition. However my case is not the same. I will migrate for a cluster smaller than in production and I was thinking that I could have the same token repartition if I combine the tokens of diferents nodes. If I can combine the tokens of differents machines, Do you see any problems if I combine also the sstables of the same machines from the old cluster to the new one ? I think to combine the tokens I can use CCM to recreate my cluster in production and then play with removenode. For info, my keyspace is rf 3 and I have 3 racks Best regards Jean Carlo "The best way to predict the future is to invent it" Alan Kay
