[BUG] Hot-Swap is not working #381

Open antejavor opened 10 months ago

antejavor commented 10 months ago

Describe the bug Once Memgraph is started and you have a QM C/C++, Rust in the form of a .so file.
Loaded and ready to use in Memgraph, after the CALL mg.load_all(); and you have tested it.

Then you decide to change something in QM and compile a new one .so file, cpto the proper location, and call: CALL mg.load_all(); Everything seems to load properly:

But the changes you have made are not included. To make it work, you need to restart the Memgraph
