hi; our cassandra cluster currently uses DSE 4.6. The underlying cassandra version is 2.0.14.
We are planning on adding multiple nodes to one of our datacenters. This requires "nodetool cleanup". The "nodetool cleanup" operation takes around 45 mins for each node. Datastax documentation recommends running "nodetool cleanup" for one node at a time. That would be really long, owing to the size of our datacenter. If we were to divert the read and write traffic away from a particular datacenter, could we run "cleanup" on multiple nodes in parallel for that datacenter?? http://docs.datastax.com/en/cassandra/2.0/cassandra/operations/ops_add_node_to_cluster_t.html thanks Sai
