84K in savings a year? Yup, that’s how much we managed to save this one company by migrating their app from Heroku over to AWS and reconfiguring their code – all because we were fine tuning performance.

When you work on a project that’s been around for quite a while, you’re probably going to - sooner or later - encounter a few skeletons in the closet. These skeletons might be sections of code or design patterns that people know about, know they are bad, and yet no one is addressing them for various reasons. Probably because nobody wants to do the redesign if the code just “works” - even if it’s terrible. What’s worse is when these same structures or patterns are being repeated, because people are blindly following them!

Working correctly with database indexes is always the key to application performance and reliability. Especially when the amount of data grows rapidly, well designed database architecture really pays off. However, when we’re working with database indexes, it can be easy to miss something, or fall into the trap of a tricky outlying case. One of these is when performing unique indexing on multiple columns, where at least one of them is null.
