1Redis TODO and Roadmap
2
3VERSION 1.2 TODO (Zsets, Integer encoding, Append only journal)
4===============================================================
5
6Most 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:
7
8* Document "masterauth" in redis.conf, also merge the other related patch if it seems a safe one.
9* SETNX and MSETNX should use lookupKeWrite() in order to expire volatile keys when a write attempt is made.
10
11VERSION 1.4 TODO (Hash type)
12============================
13
14* Hashes (HSET, HGET, HEXISTS, HLEN, ...).
15* Specially encoded memory-saving integer sets.
16* 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.
17* List ops like L/RPUSH L/RPOP should return the new list length.
18
19VERSION 1.6 TODO (Virtual memory)
20=================================
21
22* Redis Virtual Memory for datasets bigger than RAM (http://groups.google.com/group/redis-db/msg/752997c7b38553cd)
23
24VERSION 1.8 TODO (Fault tollerant sharding)
25===========================================
26
27* Redis-cluster, a fast intermediate layer (proxy) that implements consistent hashing and fault tollerant nodes handling.
28
29Interesting readings about this:

31 - http://ayende.com/Blog/archive/2009/04/06/designing-rhino-dht-a-fault-tolerant-dynamically-distributed-hash.aspx
32
33VERSION 2.0 TODO (Optimizations and latency)
34============================================
35
36* Lower the CPU usage.
37* Lower the RAM usage everywhere possible.
38* Use epool and alike to rewrite ae.c for Linux and other platforms suppporting fater-than-select() mutiplexing APIs.
39* Implement an UDP interface for low-latency GET/SET operations.
40
41VERSION 2.2 TODO (Optimizations and latency)
42============================================
43
44* 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.
45
46SHORT/LONG TERM RANDOM TODO ITEMS
47=================================
48
49Most of this can be seen just as proposals, the fact they are in this list
50it's not a guarantee they'll ever get implemented ;)
51
52* Move dict.c from hash table to skip list, in order to avoid the blocking resize operation needed for the hash table.
53* FORK command (fork()s executing the commands received by the current
54 client in the new process). Hint: large SORTs can use more cores,
55 copy-on-write will avoid memory problems.
56* DUP command? DUP srckey dstkey, creates an exact clone of srckey value in dstkey.
57* SORT: Don't copy the list into a vector when BY argument is constant.
58* 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.
59* LOCK / TRYLOCK / UNLOCK as described many times in the google group
60* Replication automated tests
61* Byte Array type (BA prefixed commands): BASETBIT BAGETBIT BASETU8 U16 U32 U64 S8 S16 S32 S64, ability to atomically INCRBY all the base types. BARANGE to get a range of bytes as a bulk value, BASETRANGE to set a range of bytes.
62* zmalloc() should avoid to add a private header for archs where there is some other kind of libc-specific way to get the size of a malloced block. Already done for Mac OS X.
63* Read-only mode.
64* Pattern-matching replication.

66DOCUMENTATION WISHLIST
67======================

69* Page explaining tips to reduce memory usage.
70* A Sorted sets HOWTO
