C＃/ MongoDB：如何保持连接存活？

Question

I'm writing a C# application which accesses a remote MongoDB. How do I go about persisting the connection while I query the database? Should I implement some sort of open/close mechanism? Or would it be better to connect once and have a time-out? I'm usign the official MongoDB / C# driver.

Answer 1

Under the hood the MongoDB C# driver maintains a connection pool, which is fairly typical in .NET. The pool works by maintaining a number of open connections for you. When you need a connection the pool will give you an existing connection (provided one is available).

The issue to avoid is a leak in your connections--if connections are opened and not closed again then you will undermine the gains of the connection pool and will need to open an additional connection every time. Also, if there is a connection leak, there's the chance it will consume extra resources on your client as well as the server.
