How can I implement MySQL connection pooling in a Python Flask or Django application?

[harishma kumar]

Hello everyone,

I am developing a web application using Python with either Flask or Django, and MySQL as the backend database. As the application grows, I want to manage database connections efficiently and avoid opening a new connection for every request.

I would like to know:

What is the recommended way to implement MySQL connection pooling in Flask or Django?

Which libraries or tools work best for connection pooling (SQLAlchemy, mysql-connector, PyMySQL, etc.)?

How should pool size and timeout values be configured for a production environment?

Are there any common mistakes or performance issues to watch out for when using connection pooling?

If possible, sample code snippets or real-world experiences would be very helpful.

Thanks in advance for your guidance.
