That looks super interesting. There seems to be a burst of innovation in this space of better developer abstractions on top of data systems recently.

I’m a sucker for a good cost calculator. This one is pretty slick. Lots of components contribute to cost in Kafka Streams.

If, on the other hand, IDEs can build proprietary adjacent tooling that integrates into developer workflows, they may become the integration point, and consequently an aggregator.

Not sure what you mean by aggregator, but for me it's something that has a 2-sided network effect. I don't know if that applies to the IDEs: If 2 IDEs use the same foundation model, what's the structural barrier for one to copy the other over the medium term?

Most banks export your credit card transactions as CSV, with categorizations. I just load that into sheets and then make a chart out of it. Since most of the spending is on CC, it works pretty well.

(1/3) One of the hardest problems in the world of stream processing is upgrading stateful applications. Why? Because the events never stop, and your application has to handle the events correctly before and after a upgrade and if rewind your position in a topic.
