…(#471) Motivation: Under high concurrency across many persistence IDs, the default journal issues separate statements and commits for each write. This increases database round-trips and connection pool contention. Modification: - Add R2dbcBatchJournal to queue writes and flush them in batches. - Add max-batch-size and max-batch-time configuration settings. - Add R2dbcBatchJournalSpec to verify TCK compliance. - Add R2dbcBatchJournalPerfSpec and R2dbcBatchJournalPerfManyActorsSpec for performance testing. Result: Users can opt in to batched writes across persistence IDs for higher write throughput. Tests: - sbt "core / Test / testOnly org.apache.pekko.persistence.r2dbc.journal.R2dbcBatchJournalSpec" - sbt "core / Test / testOnly org.apache.pekko.persistence.r2dbc.journal.R2dbcBatchJournalPerfSpec" - sbt "core / Test / testOnly org.apache.pekko.persistence.r2dbc.journal.R2dbcBatchJournalPerfManyActorsSpec" - sbt +mimaReportBinaryIssues - sbt validatePullRequest References: Fixes #471 -- This is an automated message from the Apache Git Service.
