Redis: You Shall Never Be Blamed

Mariano Valles with a story of Ruby, Redis and concurrency:

  • Concurrency issues and high loads are best friends.
  • When using unicorn or any other app server using forking to have multiple process, be careful, forks are process clones
  • Servers used as databases or willing to handle many incoming connections should be tuned accordingly: e.gprlimit —nofile 10000
  • Don’t rely on the GC for cleaning up your mess. It might work in Java, not so much in Ruby.
