Dive deep into the Pymongo MongoDB driver in this 53-minute conference talk from EuroPython 2016. Explore the inner workings of one of MongoDB's most popular driver interfaces, gaining valuable insights into how the driver constructs server requests and responds. Learn to write more effective MongoDB applications in Python by understanding initial connections, queries, simple and bulk write operations, and node failure responses. Examine the driver's approach to server selection when connecting to replica sets, and discover how to handle primary failures, elections, and recovery in replica set configurations. Investigate client-side views, topology, insert blocking, ismaster responses, and retry mechanisms. Gain practical knowledge about connection timeouts and configuration options to optimize your MongoDB applications.
