Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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

PostgreSQL Logical Replication Explained
> Logical replication is also great for replicating to other systems - for example Debezium [1] that writes all changes to a Kafka stream.
So I'm looking for a Rust library (or a C library) that receives a Postgres logical replication stream and is compatible with Postgres 15, does you know of something?
Debezium is unfortunately written in Java, and I think your Powersync is proprietary right? (I didn't find a Github link). I can find stuff like https://www.npmjs.com/package/pg-logical-replication but again, it's Javascript.

Sync databases on command
And I also found these two library that support the two plugin: - https://github.com/kibae/pg-logical-replication - https://github.com/hasura/pgdeltastream
What are some alternatives?
debezium - Change data capture for a variety of databases. Please log issues at https://issues.redhat.com/browse/DBZ.
supabase - The open source Firebase alternative.
pgdeltastream - Streaming Postgres logical replication changes atleast-once over websockets
walrus - Applying RLS to PostgreSQL WAL
Prisma - Next-generation ORM for Node.js & TypeScript | PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB and CockroachDB
