Leader Election With Ruby & PostgreSQL

The Problem

I have a table with millions of rows that needs processing. The type of processing is not really important for this article. We simply need to process some data with Ruby --or any other user-space programming language.

A Solution

# I've always disliked the way deprecation notices would appear while the test
# suite is running: they break up the neat little rows of dots (or F's, as it
# may be) which causes noise and makes the notices hard to read and understand.
#
# Adding this snippet to `config/environments/test.rb` will buffer all your
# deprecation notices until the end of the test run and keep your test output
# nice and tidy.
