Connection Pooling
Connection pooling is a performance optimization technique that maintains a cache of database connections that can be reused across multiple client requests, rather than creating and destroying connections for each request. It reduces the overhead of establishing new connections, improves application responsiveness, and helps manage resource usage efficiently in database-driven applications.
Developers should implement connection pooling in any application that makes frequent database queries, such as web servers, microservices, or enterprise systems, to avoid the latency and resource consumption of repeatedly opening and closing connections. It is essential for scaling applications under high load, as it prevents connection exhaustion and improves throughput by reusing established connections.
