Also, introduces a new GUC "citus.enable_cluster_clock", when true, every distributed transaction is stamped with logical causal clock and persisted in a catalog pg_dist_commit_transaction.	2022-10-28 10:15:08 -07:00

This implements a new UDF citus_get_cluster_clock() that returns a monotonically

increasing logical clock. Clock guarantees to never go back in value after restarts,
and makes best attempt to keep the value close to unix epoch time in milliseconds.

Also, introduces a new GUC "citus.enable_cluster_clock", when true, every
distributed transaction is stamped with logical causal clock and persisted
in a catalog pg_dist_commit_transaction.
