Michael Semb Wever commented on CASSANDRA-15393: ------------------------------------------------ {quote}Is there's a big difference between allowing performance improvements, especially ones that address real operational problems, into {{beta}} vs. {{4.0.x?}} {quote} The choice isn't binary, 4.1 is more appropriate. Was just my way of stating my concerns about this going into 4.0-beta when so much effort has been put into the feature freeze. 4.0.x would still require a waiver IMO, but with the QA/testing lifecycle guidelines from 4.0-beta better landed, and the stress and anxiety of getting 4.0 out after so long, it may then be a much easier discussion to have. Again, can we please take this to the ML, and leave the ticket for the technical? > 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.

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
