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.

All the ways to capture changes in Postgres
No. We implemented our own [1] for a few reasons:
* Scaling well to multi-TB DBs without pinning the write-ahead log (potentially filling your DB's disk) while the backfill is happening. Instead, our connector constantly reads the WAL and works well in setups like Supabase that have very restrictive WAL sizes (1GB iirc).
* Incremental fault-tolerant backfills that can be stopped and resumed at will.
* Being able to offer "precise" captures which are logically consistent in terms of the sequence of create/update/delete events.
The last one becomes really interesting when paired with REPLICA IDENTITY FULL, because you can feed it into an incremental computation (perhaps differential dataflow) for streaming updates of a continuous computation.
Our work is based off of the Netflix DBLog paper, which we took and ran with.

Why would you ever not use CDC for ELT?
Our connectors themselves are fully OSS (for example, here's PostgreSQL)

What Is Dbt and Why Are Companies Using It?
We've used https://github.com/estuary/connectors/pkgs/container/source-... to load data sets in the many terabytes. Caveat that, while it's implemented to Airbyte's spec, we've only used it with Flow.
