I work in ecommerce/erp space and I need something like this, but not JS (I using Rust now).

I tried in the past build my own but is truly hard!. I make a "event log" database but it sometimes could become so big that fill the server disk, and most events become uselles after a while. So figuring what is truly an "event is not as obvious.

Exist a paradigm that could work here? I using sqlite + postgresql (and can't move to any fancy nosql).
