Tangential, but related. Is there a way to have a "locally writable" read replica, ie. a secondary db that reads from a primary, but that can also hold local changes that doesn't send back to the primary?
One of the use cases is to have a development db that can get data from production or staging (and doesn't send local changes back)
What I've done usually is have some script/cron/worker run periodically to get data, either via dump or running some queries, create a snapshot, store it in S3, then have a script on the local dev code that gets the snapshot and inserts/restores the data in the local db. This works for many cases, but index building can be a pain (take a long time), depending on the data
