   We move away from DRBD and to filers, but only until GTID is invented.

   Replication between data centers becomes a thing, which means replication hierarchies are generally at least 3 deep, introducing intermediate primaries.

   All replication delay measurement breaks and we move to heartbeat tables for end-to-end replication delay metering.

   The Perl libraries pick up heartbeat information and moderate bulk writes by measured repliction delay automatically.
