Interclip uses Redis to cache key components of the app so they run as smoothly as possible.


What is Redis?#

From Redis on Wikipedia

Wikipedia contributors. (2021, July 7). Redis. In Wikipedia, The Free Encyclopedia. Retrieved 20:52, July 8, 2021, from

Redis is an in-memory data structure store, used as a distributed, in-memory key–value database, cache and message broker, with optional durability.

Why Redis?#

  • It's fast (the whole database is in RAM)
  • It's simple (although highly customisable, Redis is quite simple to understand and operate)

What is Redis used for?#

In Interclip, we use Redis for the two following tasks:

Storing clips#

When a new clip is created, it is added as a key in Redis with a TTL of 7 days, so if it accessed again within that time period, it is served from the cache, instead of the database.

Rate limiting#

Redis keeps a tab on the number of hits per IP (hashed IP, to be specific) and only stores the data for 30 seconds after the last request.
