Description

The goal of this story is to enable replication of postgres databases between Coordinating Nodes.

The replication process should:

  • be robust across a wide area network with potentially high latency.
  • recover consistency after being disconnected deliberately or otherwise
  • Assume a single master, with at least two, but potentially several slaves
  • Support ease of switching the master to one of the slaves (e.g. switching from cn-ucsb-1 to cn-orc-1)
