the variable number of arguments represent values, and there is no conflict
with the return value of the command.
+CLUSTER
+=======
+
+* Implement rehashing and cluster check in redis-trib.
+* Reimplement MIGRATE / RESTORE to use just in memory buffers (no disk at
+ all). This will require touching a lot of the RDB stuff around, but we may
+ hand with faster persistence for RDB.
+* Implement the slave nodes semantics and election.
+* Allow redis-trib to create a cluster-wide snapshot (using SYNC).
+* Allow redis-trib to restore a cluster-wide snapshot (implement UPLOAD?).
+
APPEND ONLY FILE
================
What happens if between 1 and 2 for some reason (system under huge load
or alike) too many time passes? We should prevent expires while the
AOF is loading.
+* #519: Slave may have expired keys that were never read in the master (so a DEL
+ is not sent in the replication channel) but are already expired since
+ a lot of time. Maybe after a given delay that is undoubltly greater than
+ the replication link latency we should expire this key on the slave on
+ access?
DISKSTORE TODO
