Change table cleanup used the upper of the whole source. No capture instance was cleaned while any export of the source was still below the as_of, and every resume upper update re-ran cleanup for every capture instance.
Replication resumes each capture instance from the least resume upper of its own exports, so each change table is now cleaned up to the meet of its exports' committed uppers, and only when that low water mark moves. A failed cleanup is retried once the low water mark moves. Cleanup remains behind
CDC_CLEANUP_CHANGE_TABLE, which defaults off.Adds
