Recently, I was talking to a long-time friend, previous university colleague and former boss, who mentioned the fact that Redis was failing to persist data to disk in low memory conditions. For that reason, he advised to never let a Redis in-memory dataset to be bigger than 50% of the system memory. Thinking about how wasteful that practice would be, it’s interesting to understand why this can happen and look for alternatives to assure that Redis will be able to use as much memory as there’s available to it, without sacrificing its durability.
