What is Connection Pooling?
Reusing a set of pre-established database connections rather than creating a new one for each request.
Why It Matters
Connection pooling dramatically improves performance and prevents your database from being overwhelmed by too many connections.
Real-World Example
A pool of 20 database connections shared across hundreds of web requests, rather than opening a new connection each time.
“Understanding terms like Connection Pooling matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
