Thank you @andatki

We have 8 members right now. Our goal is to cover 1 chapter a week and we meet every other week. Our next session will cover chapters 3 & 4.

With regards to specific topics, we have some intense queries in our app and would love to find ways to optimize them. Many are written in custom SQL and we are also trying to push them more into ActiveRecord queries. Any tips on leveraging less known ActiveRecord features that can help with performance would be extremely helpful.
