What is connection pooling and how does it work in different databases?

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.

Can you explain how connection pooling differs between SQL and NoSQL databases?

Sure! In SQL databases, connection pooling is often managed by the database driver or middleware, allowing for efficient reuse of connections. In NoSQL databases, the approach can vary; some may not require pooling due to their architecture, while others implement similar pooling strategies.

What are the benefits of using connection pooling?

The benefits include reduced latency, improved resource utilization, and better scalability. It minimizes the overhead of creating and destroying connections, leading to faster response times.

Are there any downsides to connection pooling?

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