Jonathan Ellis updated CASSANDRA-9738: -------------------------------------- Fix Version/s: (was: 3.0.0 rc1) 3.x > Migrate key-cache to be fully off-heap > -------------------------------------- > > Key: CASSANDRA-9738 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9738 > Project: Cassandra > Issue Type: Sub-task > Reporter: Robert Stupp > Assignee: Robert Stupp > Fix For: 3.x > > > Key cache still uses a concurrent map on-heap. This could go to off-heap and > feels doable now after CASSANDRA-8099. > Evaluation should be done in advance based on a POC to prove that pure > off-heap counter cache buys a performance and/or gc-pressure improvement. > In theory, elimination of on-heap management of the map should buy us some > benefit. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
