Do data dump from prod for initial sync and then setup replication from RDS to new cluster. Once synced do switch. Then you're off RDS and can shard on Citus.
- raverbashing 3y agoYes but they probably wouldn't want to migrate off RDS.
- nathanappere 3y agoThis doesn't work with the constraint of "staying on AWS" though.
