Redis is an in-memory data-structure store, which can be used as cache, queue, message broker; with configurable persistence guarantees. It is extremely elegant, performant and lightweight; which is why we are rating it as ADOPT.


  • is very performant and lightweight
  • contains many data structures to be used as building blocks for caching, queuing, distributed locking and coordination, ...
  • can be set up with replication and failover
  • is single threaded; thus easy to reason about
  • can be scripted with Lua scripts
  • will soon support streams, so it can be used as temporary log.


  • single threaded; so if you write long Lua scripts, the server cannot answer other requests at the same time.
  • the full data set has to fit in memory
