+Redis TODO
+----------
+
+WARNING: are you a possible Redis contributor?
+         Before implementing what is listed what is listed in this file
+         please drop a message in the Redis google group or chat with
+         antirez or pietern on irc.freenode.org #redis to check if the work
+         is already in progress and if the feature is still interesting for
+         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
+==============
+
+* 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
+
+* dscache.c near 236, kobj = createStringObject... we could use static obj.
+
+APPEND ONLY FILE
+================
+
+* in AOF rewirte use HMSET to rewrite small hashes instead of multiple calls
+  to HSET.
+
+OPTIMIZATIONS
+=============
+
+* Avoid COW due to incrementing the dict iterators counter.
+* 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.
+
+REPORTING
+=========
+
+* Better INFO output with sections.
+
+RANDOM
+======
+
+* Clients should be closed as far as the output buffer list is bigger than a given number of elements (configurable in redis.conf)
+* Should the redis default configuration, and the default redis.conf, just bind 127.0.0.1?
+
+KNOWN BUGS
+==========
+
+* What happens in the following scenario:
+    1) We are reading an AOF file.
+    2) SETEX FOO 5 BAR
+    3) APPEND FOO ZAP
+    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.
