Blake Eggleston updated CASSANDRA-15393: ---------------------------------------- Status: Ready to Commit (was: Review In Progress) > Add byte array backed cells > --------------------------- > > Key: CASSANDRA-15393 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15393 > Project: Cassandra > Issue Type: Sub-task > Components: Local/Compaction > Reporter: Blake Eggleston > Assignee: Blake Eggleston > Priority: Normal > Fix For: 4.0-beta > > Time Spent: 20m > Remaining Estimate: 0h > > We currently materialize all values as on heap byte buffers. Byte buffers > have a fairly high overhead given how frequently they’re used, and on the > compaction and local read path we don’t do anything that needs them. Use of > byte buffer methods only happens on the coordinator. Using cells that are > backed by byte arrays instead in these situations reduces compaction and read > garbage up to 22% in many cases. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
