PyMongo: Should I use single or multiple clients?

The question is simple: should I keep all operations to a single MongoClient? Is single client or multiple clients better than the other?

The MongoClient actually maintains a connection pool. So having multiple clients does not have any advantages. Quite the contrary, since a new client has to connect to MongoDB first, which requires a three way handshake and other overhead each time a new client is created.

Since multiple clients only have disadvantages for a single application, the answer is: Only create one client and use it everywhere you need to make a connection.
