Article & Review Request: New hot-pluggable external engine for Firebird

[Максим Крюков]

Hello everyone,

I’ve written an article about a new feature I developed for Firebird. You can find the repository here: https://github.com/mxck438/ps_engine

Would anyone be willing to fact-check the technical details or provide a brief review? If this isn't the right place for such a request, please let me know where would be best to share it.

Thanks for your time!

Maxim, this is the right place. But can you add a few words - what are the key news of that feature?

From the paper: "A primary advantage of this engine is the support for live updates to function logic, eliminating the need for server downtime."
Basically, to add a new function to a database you recompile an imlementing module, and execute "select pse_reload_module(0) from rdb$database".
The effect is instant. You as developer do not need to handle a week-long argument with DBA to reload server.

By the way, the paper is "Firebird - building hot-pluggable external functions.md" in a repository root. I admit it is lengthy, as it was written to be accessible to a broader audience.
