What is database connection pooling and why is it important?

Database connection pooling is a technique used to manage database connections efficiently. It allows multiple clients to share a pool of database connections, reducing the overhead of establishing new connections for each request.

How does connection pooling improve performance?

Connection pooling improves performance by reusing existing connections instead of creating new ones, which saves time and resources. This leads to faster response times for database queries.

What are some common libraries or frameworks that support connection pooling?

Common libraries that support connection pooling include HikariCP for Java, DBCP for Apache, and pgBouncer for PostgreSQL. These libraries help manage connections efficiently.

Are there any downsides to using connection pooling?

Yes, potential downsides include increased complexity in configuration and management, as well as the risk of exhausting the connection pool if not properly sized.
