Re: [VOTE] Release Apache Cassandra 4.1.0 GA

Hi everyone, Matt and I finished running all the tests for V2 with the bug fixes from CASSANDRA-18086 and the results for the 100 partitions are definitely better than V1. For the larger partitions (1000, 1), the results for V2 are

Could we defer the close of this vote til Monday, December 12th after 6pm Pacific Time? Jon Meredith and I have been working thru an issue blocking streaming on 4.1 for the last couple months, and are now testing a promising fix. We're currently working on a write-up, and we'd like to hold the

Here is CASSANDRA-18097 with the bug fix for the performance regression encountered with 100 partitions in V2. On Mon, Dec 5, 2022 at 2:05 PM Marianne Lyne Manaog < marianne.man...@ieee.org> wrote: > Following on what Matt said: > > - Here

Re: [VOTE] Release Apache Cassandra 4.1.0 GA

There’s another 1-line fix needed with the patch, and some tests, that I (or someone else) can likely post later today. It might be worth also giving Matt and Marianne a day or two to run some further tests to confirm everything is working as expected. > On 6 Dec 2022, at 09:15, Mick Semb

Re: [VOTE] Release Apache Cassandra 4.1.0 GA

Marianne and Matt, are you saying that this v1->v2 performance degradation is more than just CASSANDRA-18086 ? If so, what's the eta for a ticket created for it? On Tue, 6 Dec 2022 at 00:07, Marianne Lyne Manaog wrote: > Following on what Matt said: > > - Here is the link to the Cassandra repo

Following on what Matt said: - Here is the link to the Cassandra repo with the bugfix of wait time from ms to ns: https://github.com/apache/cassandra/compare/trunk...marianne-manaog:cassandra:bugfix/wait-from-ms-to-ns - the Paxos configuration used is: paxos_contention_wait_randomizer:

Re: [VOTE] Release Apache Cassandra 4.1.0 GA

Me and Marianne are also still chasing a performance issue with Paxos v2 when compared with v1. We see way more contention on v2 for a LOCAL_SERIALIZABLE workload that writes/reads to only 100 partitions (v2 performs better for higher partition counts). We're still investigating what's going on.
