EnterpriseDB Corporation ☛ Simple Guide to Clustering & Replication in Postgres
We've got this new CLI for EDB Postgres Distributed (PGD) that makes creating clusters of PGD nodes pretty easy. PGD nodes are Postgres instances with PGD metadata, all connected and talking to each other, doing logical replication of DDL (structures) and DML (data). The PGD philosophy is also pretty cloud-native in that if something goes wrong with a node we can just delete it and recreate it and it will resync all data it missed, no problem.
So I want to show you how to create a three-node PGD cluster in AWS, the easy (but still manual) way. This isn't a full production setup but it will help you get started. And then we'll play around a bit with replication and dropping and recreating nodes in the cluster.
