Show HN: I wrote a free eBook about many lesser-known/secret database tricks
This is cool! Re: multiple aggregates in one query, I wrote a Ruby gem that adds an even-more-powerful and multi-database-compatible version to ActiveRecord. (I have tested Postgres, MySQL, and SQLite are tested; others probably work, too.)

Enumerable#tally is so underused
I made activerecord-summarize because this sort of reporting is something I end up needing over and over. From a reading, writing, and maintenance perspective, I like the way you just use normal ActiveRecord methods, and the shape of the data in the block is the shape of the data in the output. You can mostly write each part of the query as if it were the only thing you were querying.

Building a dashboard in our portal that will be making heavy-ish queries to supply data to various bars/charts - would elasticsearch suffice to maximize query efficiency, or is there another best practice.
If you need to perform multiple counts and/or sums on the same table, perhaps with different groupings and filters applied, activerecord-summarize can do many aggregate operations in one pass.
- activerecord-summarize, a gem that parallelizes related .count/.sum queries by automatically building a single query to answer all of them at once
- Feedback? I made a gem that lets you run multiple ActiveRecord calculations at once to speed up your dashboards (almost) without changing your code
