Boris Badrov - Why is my query slow? An indexing story

Indexes, the get out of jail card for slow queries am I right? I mean it worked, so should we care beyond that? Like in most things in software development, it depends.

In this talk we will go on a journey and learn about:
* What is an index and how does it work?
* When should an index not be used?
* What is the cost of indexing all the indexes?
* Different types of indexes and when to use each?
* How to debug why your index isn't being used?
