+# 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

+# Note: with all the kind of policies, Redis will return an error on write
+#       operations, when there are not suitable keys for eviction.
+#
+#       At the date of writing this commands are: set setnx setex append

-# file for every redis process you are running. Redis will complain if the
-# swap file is already in use.
-#
-# The best kind of storage for the Redis swap file (that's accessed at random) 
-# is a Solid State Disk (SSD).

-# file (assuming you configured the same number of total swap file pages).
