   1 Redis TODO and Roadmap
   2
   3 VERSION 1.2 TODO (Zsets, Integer encoding, Append only journal)
   4 ===============================================================
   5
   6 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:
   7
   8 * For now only the last argument gets integer encoded, so make sure that: 1) every multi bulk command implemented will have the last arg that is indeed a value, and not used otherwise. 2) to explicitly call the function to encode the object in MSET and other commands where there are multiple "values".
   9 * Man pages for SRANDMEMBER, missing Z-commands, ...
  10 * Use strcoll() to compare objects in sorted sets, like it already happens for SORT.
  11 * Write docs for the "STORE" operaiton of SORT. Link to the article about SORT by written by defunkt.
  12 * ZRANGEBYSCORE test, ZRANGEBYSCORE LIMIT option.
  13 * Sorted sets infinity tests.
  14
  15 VERSION 1.4 TODO (Hash type)
  16 ============================
  17
  18 * Hashes (HSET, HGET, HEXISTS, HLEN, ...).
  19 * 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.
  20
  21 VERSION 1.6 TODO (Virtual memory)
  22 =================================
  23
  24 * Redis Virtual Memory for datasets bigger than RAM (http://groups.google.com/group/redis-db/msg/752997c7b38553cd)
  25
  26 VERSION 1.8 TODO (Fault tollerant sharding)
  27 ===========================================
  28
  29 * Redis-cluster, a fast intermediate layer (proxy) that implements consistent hashing and fault tollerant nodes handling.

  34
  35 VERSION 2.0 TODO (Optimizations and latency)
  36 ============================================
  37
  38 * Lower the CPU usage.
  39 * Lower the RAM usage everywhere possible.
  40 * Use epool and alike to rewrite ae.c for Linux and other platforms suppporting fater-than-select() mutiplexing APIs.
  41 * Implement an UDP interface for low-latency GET/SET operations.
  42
  43 VERSION 2.2 TODO (Optimizations and latency)
  44 ============================================
  45
  46 * 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.
  47
  48 SHORT/LONG TERM RANDOM TODO ITEMS
  49 =================================
  50
  51  * FORK command (fork()s executing the commands received by the current
  52    client in the new process). Hint: large SORTs can use more cores,
  53    copy-on-write will avoid memory problems.
  54  * SORT: Don't copy the list into a vector when BY argument is constant.
  55  * 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.
  56  * LOCK / TRYLOCK / UNLOCK as described many times in the google group
  57  * Replication automated tests
  58  * BYTEDARRAY type
  59  * 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.
  60  * Read-only mode.
