Unlike MySQL (and the MySQL manual), there are hidden variables in MongoDB that no one really documents. But they can control things such as how data sets are returned, to connection pool size/ timeouts, to even if intersections should be allowed.

In this talk, we will show you examples of these knobs, how to find them on GitHub, what they are for and when to use them.

Beyond that, we will also talk about some very unknown WiredTiger and MongoRocks internal engine settings that are useful for when your database grows and needs a bit of tweaking to save the day.
