+# EXPIRE set. It will try to start freeing keys that are going to expire
+# in little time and preserve keys with a longer time to live.
+# Redis will also try to remove objects from free lists if possible.
+#
+# If all this fails, Redis will start to reply with errors to commands
+# that will use more memory, like SET, LPUSH, and so on, and will continue

+# WARNING: maxmemory can be a good idea mainly if you want to use Redis as a
+# 'state' server or cache, not as a real DB. When Redis is used as a real
+# database the memory usage will grow over the weeks, it will be obvious if
+# it is going to use too much memory in the long run, and you'll have the time
+# to upgrade. With maxmemory after the limit is reached you'll start to get
+# errors for write operations, and this may even lead to DB inconsistency.
