Reuse a bounded set of database connections.

A connection pool lends connections to callers and reuses them after release. Its size must fit the deployment’s total capacity.
Why does connection pool matter when vibe coding?
A new pool per request defeats reuse and multiplies connection pressure.
How do you do connection pool?
Count pools across instances and define wait limits. Check concurrent load and cleanup after errors.
