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.

Choosing Between a Streaming Database and a Stream Processing Framework in Python
They manage data in the application layer and your original data stays where it is. This way data consistency is no longer an issue as it was with streaming databases. You can use Change Data Capture (CDC) services like Debezium by directly connecting to your primary database, doing computational work, and saving the result back or sending real-time data to output streams.

Generating Avro Schemas from Go types
Both of these articles mention a key player, Debezium. In fact, Debezium has had a place in the modern infrastructure. Let's use a diagram to understand why.

How the heck do I validate records with this kind of data??
This might be overkill, but you could use an extra tool like https://debezium.io to capture logs about all creates, updates, and deletes in your table

ClickHouse Advanced Tutorial: Apply CDC from MySQL to ClickHouse
Contrary to what it sounds, it’s quite straightforward. The database changes are captured via Debezium and published as events on Apache Kafka. ClickHouse consumes those changes in partial order by Kafka Engine. Real-time and eventually consistent.
