- Sometimes select count(*) from table is slow on postgres
- Sometimes you don't care about 100% accurate counts (ie. infinte scroll pagination, homepage vanity "user counts", etc)
- Sometimes, you're lazy, and google for a quick fix, and install this gem
For more background, read the Postgres wiki page on slow counting
Put this in your Gemfile
gem "postgres_loose_table_counts"
Put this in your app
@total_thingos = Thingo.loose_count # => 345523
Enjoy being that little bit more webscale.
