-- keys expire
-- sunion ssub
-- write integers in a special way on disk (and on memory?)
-- compact types for disk storing of short strings (no 4 bytes overhead!)
-- network layer stresser in test in demo
-- maxclients directive
-- check 'server.dirty' everywere
-- replication tests
-- command line client. If the last argument of a bulk command is missing get it from stdin. Example:
-    $ echo "bar" | redis-client SET foo
-    $ redis-client SET foo bar
-    $ redis-client GET foo
-    bar
-    $
-- Make Redis aware of the memory it is using thanks to getrusage() and report this info with the INFO command.
-- INFO command: clients, slave/master, requests/second in the last N seconds, memory usage, uptime, dirty, lastsave

-FUTURE
+ * SDIFF, SDIFFSTORE
+ * Add number of keys for every DB in INFO
+ * maxmemory support
+ * maxclients support
+ * Resize the expires and Sets hash tables if needed as well? For Sets the right moment to check for this is probably in SREM
+ * TTL command that returns -1 if a key is not volatile otherwise the time to live of a volatile key in seconds.
+ * What happens if the saving child gets killed or segfaults instead of ending normally? Handle this.
+ * Make sinterstore / unionstore / sdiffstore returning the cardinality of the resulting set.
+ * check 'server.dirty' everywere
+ * Shutdown must kill other background savings before to start saving. Otherwise the DB can get replaced by the child that rename(2) after the parent for some reason. Child should trap the signal and remove the temp file name.
+ * Objects sharing configuration, add the directive `objectsharingpool <size>`
+ * Make sure to convert all the fstat() calls to 64bit versions.
+ * Cover most of the source code with test-redis.tcl
 
-ROLLBACK command:
+AFTER 1.0 stable release
 
-    ROLLBACK UNSET x
-    SET x 10
-    EXPIRE x 3600
-    COMMIT
+ * Consistent hashing implemented in all the client libraries having an user base
+ * Use partial qsort for SORT + LIMIT. Don't copy the list into a vector when BY argument is constant.
+ * Profiling and optimization in order to limit the CPU usage at minimum
+ * 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.
+ * Elapsed time in logs for SAVE when saving is going to take more than 2 seconds
+ * LOCK / TRYLOCK / UNLOCK as described many times in the google group
+ * Replication automated tests
 
-    (multiple rollbacks are allowed)
+FUTURE HINTS
 
-    or alternatively
-
-    TRANSACTION SET x 1000
-    TRANSACTION EXPIRE x 1000
-    COMMIT

-    but this sucks since there is no way to check the error message.
+- In memory compression: if in-memory values compression will be implemented, make sure to implement this so that addReply() is able to handle compressed objects, just creating an uncompressed version on the fly and adding this to the output queue instead of the original one. When insetad we need to look at the object string value (SORT BY for example), call a function that will turn the object into an uncompresed one.
