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.

PostgreSQL Is Enough
WalEx instead of pub/sub (listen/subscribe): https://github.com/cpursley/walex

Introducing Read Replicas
To make use of your read replicas, copy your connection string for the read replica, update your apps to use the new read replica and you are done! A unique connection pool is also provisioned for each read replica via Supavisor.

Supavisor 1.0: a scalable connection pooler for Postgres
[I'm on the supabase team]
You can find the code/docs here: https://github.com/supabase/supavisor
This release adds support for
- SQL Parsing
- Load balancing
- support for named prepared statement
- query cancellation
It's also now available on all new databases in Supabase. For some more background on scalability, we have some benchmarks available here:

PgBouncer 1.21.0 released with prepared statement support
PgBouncer maintainer here, so obviously biased. But I think currently PgBouncer should still be the default connection pooler that you choose. There's a few newer options: Odyssey, pgcat, and supavisor. But all focus on a solving 1 or 2 specific problems that PgBouncer did not solve well, while not solving many of the other problems that PgBouncer does solve. So if you have the exact same requirements as the authors of those tools, then switching might be good. But otherwise you should probably continue using PgBouncer.
Supavisor specifically is really immature. It's missing some really core functionality like query cancellations: https://github.com/supabase/supavisor/issues/174
I did a talk on this exact topic at PGConf NYC recently. My slides are here: https://github.com/JelteF/slides/raw/main/2023-10-05-future-...

How to Listen to Database Changes Using Postgres Triggers in Elixir
Phoenix.PubSub is basically a noop service. It really just works. You should try it!
If discovering nodes is difficult in your env, try using a listen/notify libcluster strategy:

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.

ClickHouse Advanced Tutorial: Apply CDC from MySQL to ClickHouse
Contrary to what it sounds, itโs 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.
