Understanding Connection Pooling in Go's MGO Package

The mgo package in Go offers a convenient way to connect to and interact with a MongoDB database. However, the documentation's lack of explicit mention of connection pooling has raised some questions.

How does Connection Pooling Work in MGO?

The connection pool in MGO is managed automatically behind the scenes. When you call mgo.DialWithInfo() to establish a connection, it creates a session that maintains a pool of socket connections to MongoDB. This pool helps optimize subsequent requests by reusing existing connections, resulting in improved performance.

Does mgo.DialWithInfo() Create a Connection Pool?

Yes, mgo.DialWithInfo() creates a connection pool. However, it is worth noting that the mgo.Dial() function also creates a connection pool, which is then shared by subsequent sessions created using session.New() or session.Copy().

Conclusion

Connection pooling in MGO is a valuable feature that enhances connection efficiency. By leveraging the connection pool, you can minimize overhead and optimize the performance of your MongoDB interactions.
