 Redis TODO and Roadmap
 

-VERSION 1.2 TODO (Zsets, Integer encoding, Append only journal)
-===============================================================
-
-Most of the features already implemented for this release. The following is a list of the missing things in order to release the first beta tar.gz:
-
-* When Redis runs as slave make sure to set the fake client it uses to talk to the master as c->authenticated = 1 to avoid problems with slaves with requirepassword set.
-* Document BGREWRITEAOF.
-

 VERSION 1.4 TODO (Hash type)
 ============================
 
 VERSION 1.4 TODO (Hash type)
 ============================
 

-* Blocking LPOP (BLPOP).
-* Hashes (HSET, HGET, HEXISTS, HLEN, ...).
+* BRPOPLPUSH
+* RPOPLPUSH should notify blocking POP operations

 * List ops like L/RPUSH L/RPOP should return the new list length.
 * List ops like L/RPUSH L/RPOP should return the new list length.

+* Save dataset / fsync() on SIGTERM
+* MULTI/EXEC should support the "EXEC FSYNC" form
+* Synchronous Virtual Memory
+* BLPOP & C. tests (write a non blocking Tcl client as first step)

 
 VERSION 1.6 TODO (Virtual memory)
 =================================
 
 
 VERSION 1.6 TODO (Virtual memory)
 =================================
 

-* Redis Virtual Memory for datasets bigger than RAM (http://groups.google.com/group/redis-db/msg/752997c7b38553cd)
+* Asynchronous Virtual Memory
+* Hashes (HSET, HGET, HEXISTS, HLEN, ...).

 SMALL ONES:
 
 * Give errors when incrementing a key that does not look like an integer, when providing as a sorted set score something can't be parsed as a double, and so forth.
 * MSADD (n keys) (n values). See this thread in the Redis google group: http://groups.google.com/group/redis-db/browse_thread/thread/e766d84eb375cd41

+* Remove keys when a list / set / zset reaches length of 0.

 it's not a guarantee they'll ever get implemented ;)

-======================

-* Page explaining tips to reduce memory usage.
-* A Sorted sets HOWTO
-
+* Add an option to relax the delete-expiring-keys-on-write semantic *denying* replication and AOF when this is on? Can be handy sometimes, when using Redis for non persistent state, but can create problems. For instance should rename and move also "move" the timeouts? How does this affect other commands?
+* Multiple BY in SORT.
