-VM TODO
-=======
+DISKSTORE TODO
+==============
 
-* Use multiple open FDs against the VM file, one for thread.
-* Check what happens performance-wise if instead of creating threads again and again the same threads are reused forever. Note: this requires a way to disable this clients in the child, but waiting for empty new jobs queue can be enough.
-* mmap the swap file.
-* Use just a single IO Job to swap out a key, and add a mutex so that pages in the page table can be marked as used and scanned from the thread itself.
+* 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
 
-REPLICATION

+APPEND ONLY FILE
+================
 
-* PING between master and slave from time to time, so we can subject the
-master-slave link to timeout, and detect when the connection is gone even
-if the socket is still up.
+* in AOF rewirte use HMSET to rewrite small hashes instead of multiple calls
+  to HSET.
 
 OPTIMIZATIONS

 * 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?
