          us, and *how* exactly this can be implemented to have good changes
          of a merge. Otherwise it is probably wasted work! Thank you
 
-DISKSTORE TODO
-==============
 
-* Fix FLUSHALL/FLUSHDB: the queue of pending reads/writes should be handled.
-* Check that 00/00 and ff/ff exist at startup, otherwise exit with error.
-* Implement sync flush option, where data is written synchronously on disk when a command is executed.
-* Implement MULTI/EXEC as transaction abstract API to diskstore.c, with transaction_start, transaction_end, and a journal to recover.
-* Stop BGSAVE thread on shutdown and any other condition where the child is killed during normal bgsave.
-* Fix RANDOMKEY to really do something interesting
-* Fix DBSIZE to really do something interesting
-* Add a DEBUG command to check if an entry is or not in memory currently
+API CHANGES
+===========
 
-* dscache.c near 236, kobj = createStringObject... we could use static obj.
+* Turn commands into variadic versions when it makes sense, that is, when
+  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

@@ -36,6 +41,8 @@ OPTIMIZATIONS
 * SORT: Don't copy the list into a vector when BY argument is constant.
 * Write the hash table size of every db in the dump, so that Redis can resize the hash table just one time when loading a big DB.
 * Read-only mode for slaves.
+* Redis big lists as linked lists of small ziplists?
+  Possibly a simple heuristic that join near nodes when some node gets smaller than the low_level, and split it into two if gets bigger than high_level.

     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?
