Show HN: Polynya – Turn your Postgres into workspaces for AI

https://polynya.dev/
4•hasyimibhar•2h ago
The idea is simple: AI agents need real-time data to be useful. But streaming real-time data into your data warehouse means you need the data warehouse to be up 24/7. This is expensive and wasteful. What if you could spin up an ephemeral data warehouse only when your agent needs it, and get real-time data at the same time?

The solution: Polynya replicates your data into Iceberg, and gives your agent an ephemeral ClickHouse instance on demand. Polynya also provides persistent workspaces — collections of views that survive across sessions. So from your agent's point of view, it's a 24/7 data warehouse.

At its core, Polynya is a data platform for streaming real-time data from Postgres to Iceberg. But instead of spending hours setting up costly and complex pipelines involving Kafka, Debezium, Flink, etc., Polynya lets you do this with just one command:

npx polynya create

It's currently free on early access, so do try it out and give me any feedback! Currently there is no web dashboard yet (coming soon), you interact with it 100% through CLI.

P.S. Polynya is built on top of pg2iceberg, the open source Postgres to Iceberg replication tool I've been building for the past few weeks: https://pg2iceberg.dev/
