On the performance of REPLICA IDENTITY FULL in Postgres
To illustrate the above, let’s look at an example, using wal2json for convenience. An update event looks something like this:
-
What is the recommended way to synchronize data between Postgres and Elasticsearch?
You could also use tools in conjunction with logical replication to stream changes, like debezium or wal2json.

DMS or Debezium for CDC for legacy system
I've done CDC before for mysql and postgres, in both cases, rolled my own 200~ loc python scripts. No experience with DMS. Debezium, as I understand, needs a kafka topic to stream to, so wasn't workable for us. Rolling our own proved to be fairly trivial. For postgres, there's wal2json https://github.com/eulerto/wal2json

Sync databases on command
I was researching for the whole day and found out https://github.com/eulerto/wal2json and postgres bult-in `pgoutput` plugin help me to catch the changes.

Looking for a Rails Gem that Audits Manual Database Changes
I don't think this is something for "rails" to do per se, and more the underlying DB. replication tools to capture a "change log". I have use postgres Write Ahead Logs (WAL) shipped to s3 in json format https://github.com/eulerto/wal2json

Realtime: Multiplayer Edition
Wen Bo from the Supabase Realtime team here!
We actually use https://github.com/supabase/walrus to get the database changes and we're planning on moving to a Rust worker (https://github.com/supabase/walrus/tree/worker/worker) for better performance especially in the RLS-enabled use case.
I promised José that I would check out Postgrex.ReplicationConnection and we might add it in to our Supabase Realtime some time in the future.

Supabase limitations ? Any reasons not to use?
We are adding this to the database now: https://github.com/supabase/walrus
What are some alternatives?
debezium - Change data capture for a variety of databases. Please log issues at https://issues.redhat.com/browse/DBZ.
symmetric-ds - SymmetricDS is database replication and file synchronization software that is platform independent, web enabled, and database agnostic. It is designed to make bi-directional data replication fast, easy, and resilient. It scales to a large number of nodes and works in near real-time across WAN and LAN networks.
supabase - The open source Firebase alternative.
pgvector - Open-source vector similarity search for Postgres
pg-logical-replication - PostgreSQL Logical Replication client for node.js
realtime - Broadcast, Presence, and Postgres Changes via WebSockets
zombodb - Making Postgres and Elasticsearch work together like it's 2023
container-images - Docker images for Debezium. Please log issues in our JIRA at https://issues.redhat.com/projects/DBZ/summary
mria - Asynchronously replicated Mnesia-like database for Erlang/Elixir
