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

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.
