* Fix DBSIZE to really do something interesting
* Add a DEBUG command to check if an entry is or not in memory currently
-REPLICATION
-===========
+* dscache.c near 236, kobj = createStringObject... we could use static obj.
-* 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.
+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.
