This seems very good. Always wondering what are the usecases for this apart for observability/real-time analytics? Do people use this for incremental view maintenance in Postgres?

I'm thinking of using it to replace an analytics pipeline at my job, which now uses expensive batch jobs. If the tech is solid, we would have instant and incremental updates, instead of recomputing everything every X hours. This would simplify things a lot.

I think Materialize offers a similar product, but last I checked it was only available as a SaaS solution.

I hope to do a proof of concept soon, to compare both solutions

materialize now offers a self managed version of the product https://materialize.com/docs/self-managed/v25.1/

The use case section also mentions Event-driven applications which is quite broad. Like other comment on the thread I'd be curious to hear about anyone having experience with RisingWave in this use case area.

Replied above, used it for triggering actions based on lack of or presence of data points.
