Stefania commented on CASSANDRA-12212: -------------------------------------- Thanks for clarifying. If I understood correctly, given that when local shards get reconciled with global shards we take the global shard, and counter mutations in 2.1+ create global shards, we shouldn't have any compactions in progress that need to reconcile two local shards unless people have been using 2.1 only for a very short period of time. So the only legitimate case would be the case when 2.1 is installed as an intermediate release before upgrading to 3.0. Is this accurate? > system.compactions_in_progress needs to be used on first upgrade to 3.0 > ----------------------------------------------------------------------- > > Key: CASSANDRA-12212 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12212 > Project: Cassandra > Issue Type: Bug > Components: Compaction > Reporter: Jeremiah Jordan > Assignee: Stefania > Fix For: 3.0.x, 3.x > > > CASSANDRA-7066 removed the system.compactions_in_progress table and replaced > it with the new transaction system.
