Example of using the connection pool about mongo-rust-driver-prototype HOT 3 CLOSED

Hey, I didn't see this issue until now! The connection pool is maintained internally by a MongoDB Client, so you shouldn't ever have to deal with the pool directly. MongoDB apps are designed to have one Client across the entire application, so developers can clone Client (which is actually an alias of an Arc type), allowing them to use multiple references of the same connection pool.

This is discussed a little bit in #135.

... Client is actually just an alias of an Arc type, which means you can open the connection at the top of the function and then just use .clone() to get an (owned) atomic reference to it inside each of your routes that need it.

It sounds like you are doing this in your application, which is great! If you're using cloned references to a single Client, the internal connection pool will automatically handle connection recycling for you and create new connections under heavy load.

Very good, thanks!

Can I set the pool size?
