In addition, the Redis config file allows you to specify an eviction policy when the maximum memory limit is reached:

  # volatile-lru -> remove the key with an expire set using an LRU algorithm
  # allkeys-lru -> remove any key accordingly to the LRU algorithm
  # volatile-random -> remove a random key with an expire set
  # allkeys-random -> remove a random key, any key
  # volatile-ttl -> remove the key with the nearest expire time (minor TTL)
  # noeviction -> don't expire at all, just return an error on write operations
