In this article, we will look at how this can improve the reporting/analytical query performance in MySQL. I’m using the “Airlines On-Time Performance” database from [link] (You can find the scripts I used here: [link] ). Result: ~10x performance gain, no index used. Summary of simple query performance. MySQL on ec2.
