A deep dive into the Pymongo MongoDB driver

*The Pymongo driver is one of MongoDB’s most popular driver interfaces for connecting to MongoDB. But developers rarely look under the cover to see what’s happening inside the driver. *

By having a deeper insight into how the driver constructs server requests and responds, developers will be able to write more effective MongoDB applications in Python.

We will look at :

-

Initial connection

A query

A simple write operation

A bulk write operation

How the driver responds when we have a node failure

We will also give insight into the driver’s approach to server selection when connecting to a replicas set (a multi-node instance of MongoDB).
