Amazon RDS Read Replicas (Oct 2010) [1]
- Amazon RDS Read Replicas, Postgres: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PostgreSQL.Replication.ReadReplicas.html
- You can create up to 5 read replicas from one source DB instance
- You can't stop a DB instance that has a read replica, or that is a read replica.[2]
- Point-in-time recovery (PITR) isn't supported for read replicas. You can use PITR with a primary (writer) instance only, not a read replica. To learn more, see Restoring a DB instance to a specified time for Amazon RDS.
