How about hobbes?

I will check thanks but wnated to learn from him. I do not think there are many alternatives by the way. Is this one a full alternative? Does it provide all functionalities of kdb?

It’s better in a lot of ways. It has a type system, can produce much better code, can do cross-process compilation (for multi-process IPC). The FFI/binding process is much simpler, there are more options to record precisely-typed data from applications.

And hobbes is used in major high-volume and low-latency systems at Morgan Stanley (where q originated, as you may know).

Hi thank you very much, I work in the industry and I will definitely take a look at it. You seem to be one of the developers behind this project. Is there any way I can contact you in the future?

Yes I do work on the project at Morgan Stanley. Our group email is [email protected] and we're pretty responsive on that list (as well as on the github page).

How come kx is ok with this one? I heard they sue every moving object around.

Kx does seem to bully people with threats of lawsuits, not sure how often they actually follow through.

hobbes is not a k/q clone, it's much more like Haskell actually. The features that make hobbes especially compelling for its production use-cases, like its complex type system, are features that kdb has never had and probably never will have.
