Working set calculations
The working set in MongoDB is a vital concept that pertains to the amount of data and indexes that a database accesses over a specific period. This data should ideally be held in the system's RAM to guarantee optimal performance. When it comes to database performance, understanding your working set is pivotal. While MongoDB is capable of managing vast datasets, the speed of data retrieval is significantly affected by whether the data is accessed directly from the RAM or fetched from a disk. Accessing data from the RAM is exponentially faster, which is why the working set—data that is frequently accessed—should ideally reside in memory.
Why is the working set crucial?
As your MongoDB instance serves requests, it tends to pull the required data into RAM. Over time, the most frequently accessed data—your working set—naturally find its place in memory. If this working set fits comfortably in RAM, your database performance...
