MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Just wanted to see if someone with experience in running an actual service can advise me: how often do you run nodetool compact on your nodes? Do you stagger it in time, for each node? How badly is performance affected? I know this all seems too generic but then again no two clusters are created equal anyhow. Just wanted to get a feel.
