Brandon Williams commented on CASSANDRA-12668: ---------------------------------------------- Can you add a little more color to 'fall apart'? > Memtable Contention in 2.1 > -------------------------- > > Key: CASSANDRA-12668 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12668 > Project: Cassandra > Issue Type: Bug > Reporter: sankalp kohli > > We added a new Btree implementation in 2.1 which causes write performance to > go down in Cassandra if there is lot of contention in the memtable for a CQL > partition. Upgrading a cluster from 2.0 to 2.1 with contention causes the > cluster to fall apart due to GC. We tried making the defaults added in > CASSANDRA-7546 configurable but that did not help. Is there anyway to fix > this issue? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
