+- RAFT is the fabric that holds together your PostgreSQL containers
+- External consistent key-value store instead of a built-in one:
+ advantages:
+ - PostgreSQL failure doesn't break the consensus
+ - use well-tested RAFT implementations (i.e. Etcd or Consul)
+ disadvantages:
+ - one needs to operate extra services
+Features:
+- synchronous vs asynchronous replication (consistency vs availability)
+- some parameters need to be kept in sync on all cluster nodes (max_connections)
