What about "incremental repair" and "sequential repair"?
I ran "nodetool repair -- keyspace table" on one node. I found the repair sessions running on different nodes. Will this command repair the whole table? In this page: http://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_repair_nodes_c.html#concept_ds_ebj_d3q_gk__opsRepairPrtRng *Using the nodetool repair -pr (–partitioner-range) option repairs only the first range returned by the partitioner for a node. Other replicas for that range still have to perform the Merkle tree calculation, causing a validation compaction.* Does it sound like -pr runs on one node? I'm still don't understand "the first range returned by the partitioned for a node"?
