+=item MEMCACHED_BEHAVIOR_RANDOMIZE_REPLICA_READ
+
+Allows randomizing the replica reads starting point. Normally the read is
+done from primary server and in case of miss the read is done from primary
++ 1, then primary + 2 all the way to 'n' replicas. If this option is set
+on the starting point of the replica reads is randomized between the servers.
+This allows distributing read load to multiple servers with the expense of
+more write traffic.
