I read this nice article about Understanding EXPLAIN [1] weeks ago that opened my mind about the tool, but it seems no enough to explain a lot of plans that I see in this list.
Thanks.
I often read responses to a plan that are not covered by the article.
I need/want to know EXPLAIN better.
Can you kindly advise me a good reading about advanced EXPLAIN?
There's not much out there. This document was written after reading this list, viewing some talks (you may find a lot of them on youtube), and reading the code.
I intend to update this document, since I learned quite more since 2012. Though I didn't find the time yet :-/
