Strongly agree with the author here. The future will belong to programming languages that natively embed theorem proofers into their type systems so LLMs can forego a lot of testin…

That would be surprising to me if anyone would think this is novel. Using bitmaps to indicate whether things are in-use or not is very common in systems programming. Like you said …

Haha, looks like it. I remember the first time I encountered this thing called TPC-H back when I was a student. I thought "wow surely SQL can't get more complicated than that". Tur…

Yep pretty much, feldera is the engine we don't control what SQL people throw at us.

Feldera is an incremental query engine, you can think of it as a specialized database. If you have a set of question you can express in SQL it will ingest all your data and build m…

Yep, this comment sums it up well. We have many large enterprises from wildly different domains use feldera and from what I can tell there is no correlation between the domain and …

Hi, I'm the author of the article. As to your hard disagree, I guess it depends... While this particular user is on the higher end (in terms of columns), it's not our only user whe…

feldera has a way to run ad-hoc/list queries on materialized views. Alternatively, you can send the result somewhere where you can query it.

I believe that was more a bug in the firmware that's been fixed for a while now.
