Redis TODO and Roadmap
VERSION 1.1 TODO (Zsets, Integer encoding, Append only journal)
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:

* Man pages for SRANDMEMBER, missing Z-commands, ...
* Use strcoll() to compare objects in sorted sets, like it already happens for SORT.
* Write docs for the "STORE" operaiton of SORT. Link to the article about SORT by written by defunkt.
* Append only mode: testing and a command to rebuild the log from scratch.
* ZRANGEBYSCORE test, ZRANGEBYSCORE LIMIT option.
* Sorted sets infinity tests.
* Instead to do the lamest thing of using getDecodedObject only if the encoding
of the object != REDIS_ENCODING_RAW, hack getDecodedObject in order to just
increment the reference count if the object is already RAW-encoded.
VERSION 1.2 TODO (Hash type)
VERSION 1.4 TODO (Hash type)
============================
* Hashes (HSET, HGET, HEXISTS, HLEN, ...).
* An utility able to export an .rdb file into a text-only JSON dump, we can't live anymore without such a tool. Probably an extension to redis-cli.
VERSION 1.3 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)
VERSION 1.4 TODO (Fault tollerant sharding)
VERSION 1.8 TODO (Fault tollerant sharding)
===========================================
* Redis-cluster, a fast intermediate layer (proxy) that implements consistent hashing and fault tollerant nodes handling.

VERSION 1.5 TODO (Optimizations and latency)
VERSION 2.0 TODO (Optimizations and latency)
============================================
* Lower the CPU usage.

* Use epool and alike to rewrite ae.c for Linux and other platforms suppporting fater-than-select() mutiplexing APIs.
* Implement an UDP interface for low-latency GET/SET operations.
VERSION 2.2 TODO (Optimizations and latency)
============================================
* JSON command able to access data serialized in JSON format. For instance if I've a key foobar with a json object I can alter the "name" file using somthing like: "JSON SET foobar name Kevin". We should have GET and INCRBY as well.
SHORT/LONG TERM RANDOM TODO ITEMS
=================================
* FORK command (fork()s executing the commands received by the current
client in the new process). Hint: large SORTs can use more cores,
copy-on-write will avoid memory problems.
* 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.
* LOCK / TRYLOCK / UNLOCK as described many times in the google group
