I’m new in Cassandra and trying to figure out how to _start_ using incremental repairs. I have seen article about “Migrating to incremental repairs” but since I didn’t use repairs before at all and I use Cassandra version v3.0.8, then maybe not all steps are needed which are mentioned in Datastax article. Should I start with full repair or I can start with executing “nodetool repair -pr my_keyspace” on all nodes without autocompaction disabling and node stopping?
I have 6 datacenters with 6 nodes in each DC. Is it enough to run “nodetool repair -pr my_keyspace” in one DC only or it should be executed on all nodes in _all_ DCs? I have tried to perform “nodetool repair -pr my_keyspace” on all nodes in all datacenters sequentially but I still can see non repaired SSTables for my_keyspace (Repaired at: 0). Is it expected behavior if during repair data in my_keyspace wasn’t modified (no writes, no reads)?
