We need a way to switch just one node so we can slowly roll out a huge change like this. doing the whole cluster brought it to it's needs and we tried nodetool stop compaction on some nodes but that did not help at all. We had to really wait overnight for all LCS to finish. > We had also tried nodetool setcompactionthroughput 1 which also had no effect and performance was still pretty bad. Ideally, none of this would be a problem if we were just doing one node as we would just pull the node back out while it was converting to LCS. -- This message is automatically generated by JIRA.
