Replica Preserve Commit Order and Measuring Lag
With multi-threaded replication (MTR), a replica can commit transactions in the same order as the source, or not. This is determined by sysvar replica_preserve_commit_order (RPCO).

In either case, it’s relatively new compared to 20+ years of single-threaded replication for which commit order was not an issue or option. But with MTR, it’s important to understand the affects of RPCO, especially with respect to the focus of this three-part series: replication lag.
