- mongoTuning.js is a master script, compiling a number of helper functions into a single object that is used throughout the book.
- The examples folder contains some example scripts for using some of our helper functions along with output..
- The sampleData directory contains all the data used in our examples as a compressed dump file. Instructions on how to load the data can be found in the same folder.
- The scripts directory contains all the individual scripts which together create the master script(mongoTuning.js) along with some additional scripts that may not be used.
- The misc directory contains some files or data that is referenced in the book but not directly by the scripts, for example some sample alarms and metric calculations that readers may find userful.
- ExplainPlanSteps.md contains a breakdown of the various different stages you may encounter in an explain plan, along with a simple explanation of that stage.
