issue: #43897 - UpdateReplicateConfig operation will broadcast AlterReplicateConfig message into all pchannels with cluster-exclusive-lock. - Begin txn message will use commit message timetick now (to avoid timetick rollback when CDC with txn message). - If current cluster is secondary, the UpdateReplicateConfig will wait until the replicate configuration is consistent with the config replicated from primary. --------- Signed-off-by: chyezh <chyezh@outlook.com>
