The general upshotofthisis: Don't share connections between threads. It's really not worth your effort or mine, and in the end, will probably hurt performance, since the MySQL server runs a separate thread for each connection. You can certainly do things like cache connections in a pool, ...
Hence, we need to implement our own composite object in order to share objects between threads to make the communication thread-safe. Following are a few data structures, which provide thread-safe communication after making some changes in them −...
Threads work in the same way. A CPU is giving you the illusion that it's doing multiple computations at the same time. It does that by spending a bit of time on each computation. It can do that because it has an execution context for each computation. Just like you can share a book...

The problem in this mechanism was that most of the time the CPU-bound thread would reacquire the GIL itself before other threads could acquire it. This was researched by David Beazley and visualizations can be found here.This problem was fixed in Python 3.2 in 2009 by Antoine Pitrou who ...
