Jonathan Ellis updated CASSANDRA-5348: -------------------------------------- Summary: Remove on-heap row cache (was: Remove row cache until we can replace it with something better) > Remove on-heap row cache > ------------------------ > > Key: CASSANDRA-5348 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5348 > Project: Cassandra > Issue Type: Task > Components: Core > Reporter: Jonathan Ellis > Assignee: Jonathan Ellis > Fix For: 2.0 > > Attachments: 5348.txt > > > The row (partition) cache easily does more harm than good. People expect it > to act like a query cache but it is very different than that, especially for > the wide partitions that are so common in Cassandra data models. > Making it off-heap by default only helped a little; we still have to > deserialize the partition to the heap to query it. > Ultimately we can add a better cache based on the ideas in CASSANDRA-1956 or > CASSANDRA-2864, but even if we don't get to that until 2.1, removing the old > row cache for 2.0 is a good idea. -- This message is automatically generated by JIRA.
