Scaling Postgres Listen Notify Pgdog

Scaling Postgres Listen Notify Pgdog That limitation seemed a bit arbitrary, so we added support for listen notify to pgdog. now, you can have thousands of listeners and just as many publishers, without adding specialized message brokers to your stack. This is the story of what happened, how we ended up discovering a bottleneck in the listen notify feature of postgres (the event notifier that runs based on triggers when something changes in a row), and what we ended up doing about it.

Postgres Listen Notify Does Not Scale Pgdog is a proxy for scaling postgresql. it supports connection pooling, load balancing queries and sharding entire databases. written in rust, pgdog is fast, secure and can manage thousands of connections on commodity hardware. Recall.ai, a provider of meeting transcription bots, noticed that their postgresql instance was being bogged down by heavy concurrent writes. A major scaling issue with postgresql's listen notify feature has sparked widespread discussion in the developer community after recall.ai shared their experience with database performance problems. the company discovered that this seemingly harmless feature can bring down entire database systems under heavy concurrent write loads. Postgres listen notify can cause severe performance issues under high write concurrency due to a global lock during commit. learn why it doesn't scale and how to avoid outages.

Pgdog simplifies postgresql scaling by combining pooling, balancing, and sharding in one tool. for sre teams managing growing databases, it eliminates the complexity of stitching multiple solutions together. This approach simplifies your technology stack while leveraging postgresql’s built in capabilities — making it ideal for live dashboards, collaborative tools, and event driven architectures. This is the story of what happened, how we ended up discovering a bottleneck in the listen notify feature of postgres (the event notifier that runs based on triggers when something changes in a row), and what we ended up doing about it. That limitation seemed a bit arbitrary, so we added support for listen notify to pgdog. now, you can have thousands of listeners and just as many publishers, without adding specialized message brokers to your stack. this game has two players: publishers and subscribers.
