Thanks ! Is there also a way to find out the replica nodes ?

Say we have 2 DCs, DC1 and DC2 with RF=2 (DC1:1, DC2:1)

Can we find out which node in DC2 is a replica ?

This tells you where a key lives. (you need to hex encode the key)

Subject: Replica info

Is there a way in Cassandra that we can know which node has the replica for the data ? if
we have 4 nodes and RF = 2, is there a way we can find which 2 nodes have the same data ?

Thanks,
Kanwar
