Top 10 Elixir Distributed System Projects
- Project mention: Listen to Database Changes Through the Postgres WAL | news.ycombinator.com | 2025-11-16
Worth mentioning that WAL is enabling and used by Supabase Realtime [0] and WalEx [1] which both are doing very similar thing - polling the WAL changes in order to emit them as Websocket events.
I never worked with WalEx but have experience with Supabase Realtime and it is a joy to work with and fits great into the Supa ecosystem. So many layers are disappearing when you rely more on Postgres!
