lantao yan commented on CASSANDRA-5078: --------------------------------------- sorry for the late update. pretty busy recently. even missed Jonathan's London meetup. :) For the conflict on the entry, I don't quite get it. I read the code, it seems like one directory (one column family) will be owned by one thread? so there won't be any chances, two threads are working on the same column family with the same timestamp? I could be wrong. If I miss something, please let me know. > save compaction merge counts in a system table > ---------------------------------------------- > > Key: CASSANDRA-5078 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5078 > Project: Cassandra > Issue Type: Improvement > Reporter: Matthew F.
