Well I had originally planned to write it in go and rust, with go as the single api interface and rust workers like a blackbox that took the live ticker stream and gave back signals with confidence.

However the development time with rust especially with a lot of multi threaded increased the development time a lot, since I am kinda new to it, then I migrated that module to java...wanted to see the performance gains with the recent gc optimizations in Java 21 and 23

Its very experimental rn. On a very high level it is just a function scheduler. It is very good at handling thousands of tickers and then can schedule and what functions to run when. The functions have defined templates from which they inherit so they can use the cache and send signals. Then there are os threads who are querying the schedules for tickets and what functions to run.
