I'm not trying to cause problems i swear 😂 i know this is as beast and we can schedule a call to go over it or whatever is needed.
I really needed connection pooling and the test file was insanely big 😂 and so i had to 'yak shave' 🪒 to get there.
Also for mariadb this adds in breaking changes as you must specify the charset and the collation for the connection pool to work. So we'd need to increment a major or minor version etc.
I'm working on fixing the build.
