MySQL has recently dropped it's new 26.7 Early Preview, and wow - they've included Thread Pooling.
This is the one feature that most enterprises require their commercial flavour for!
Once you've upgraded to this version, you'll need to load the thread pool plugin:
plugin-load-add=thread_pool.so
And that's it! To see it working, you can grab some stats by running:
SELECT * FROM information_schema.TP_THREAD_GROUP_STATS
