Robert Stupp commented on CASSANDRA-9738: ----------------------------------------- Pushed some more commits. Includes serialization of IndexInfo offsets. Adds tests for RowIndexEntry class and legacy sstables based on CASSANDRA-10236 (latter not working yet due to CASSANDRA-10237). Open todo: benchmarking/comparison against "old" implementation, verification of compatibility with legacy sstables. > 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: 3.0 beta 2 > > > 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)
