#The ObjectRocket Customer Support Story We had an RTG customer using Redis as a cache for their web-app. They were receiving write errors from Redis in their application as writes were attempted. Usually this is due to running out of available memory in Redis. After diagnosing the issue, we were able to quickly update their maxmemory policy to resolve the problem. How, and why, did this solve their problem? There are a few things to know about key eviction and the various maxmemory policies available in Redis.
Redis can be configured to behave differently when the database gets full. There are various options to recycle memory used by less important keys (through eviction) to allow for continued writes. Key eviction operations are the same as key deletions: the key is no longer accessible and the memory it occupied is marked as available for overwriting. What does it mean for the Redis db to be "full" though?
If we do not specify a
maxmemory value in the Redis configuration, Redis will continue to a
