org.apache.james.mailbox.cassandra.CassandraMailboxManagerTest$WithBatchSize.creatingConcurrentlyMailboxesWithSameParentShouldNotFail tests is enough to trigger instability on the Apache CI https://ci-builds.apache.org/job/james/job/ApacheJames/job/PR-685/1/ In short, the LWT usage is enough to create contention. Looking closer at the issue, StoreMailboxManager does numerous defensive SERIAL reads (doing empty paxos commits) which ends up further degrading performance and increase contention. I believe removing these defensive reads would make our code more stable. It resulted in faster (x2) test for gConcurrentlyMailboxesWithSameParentShouldNotFail -- This is an automated message from the Apache Git Service.
