Explain the role of connection pooling in database interaction in Go.

Connection pooling plays a crucial role in database interaction in Go. It involves efficiently managing database connections to avoid the overhead of opening and closing connections for every query. Instead, a pool of connections is created and maintained, allowing applications to reuse existing connections when needed. This improves performance by reducing connection establishment overhead. Connection pooling also helps manage the number of concurrent connections to the database, preventing resource exhaustion and optimizing resource utilization. Efficient connection pooling is essential for scalable and high-performance database interactions in Go applications.
