Rate Limiting With Redis

Rate limiting can be an effective way of conserving resources and preventing automated or nefarious activities on your site.

The key issues to address when designing a solution are:

  1. How do we incorporate time given that it’s a continuous variable?
  2. How can we efficiently expire old data?
  3. How can we scale the solution so that it can handle many hundreds of subjects and/or actions per second?

Chris O’Hara explains how each of these has a good answer in Redis’ features.
