What are the best practices for MongoDB connection pooling?

The best practices for MongoDB connection pooling include setting an appropriate pool size, using connection timeouts, and monitoring connection usage.

How do I determine the right pool size for my application?

The right pool size depends on your application's workload and the number of concurrent operations. A common approach is to start with a size equal to the number of application threads and adjust based on performance.

What are the consequences of having too many connections?

Having too many connections can lead to resource exhaustion, increased latency, and potential application crashes due to overwhelming the database server.

Can you explain how to monitor connection usage?

You can monitor connection usage using MongoDB's built-in monitoring tools like the db.serverStatus() command, which provides insights into current connections and their status.
