   1 Redis TODO and Roadmap
   2
   3 VERSION 1.1 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 * Append only mode: testing and a command to rebuild the log from scratch.
  13 * ZRANGEBYSCORE test, ZRANGEBYSCORE LIMIT option.
  14 * Sorted sets infinity tests.
  15 * Instead to do the lamest thing of using getDecodedObject only if the encoding
  16   of the object != REDIS_ENCODING_RAW, hack getDecodedObject in order to just
  17   increment the reference count if the object is already RAW-encoded.
  18
  19 VERSION 1.2 TODO (Hash type)
  20 ============================
  21
  22 * Hashes (HSET, HGET, HEXISTS, HLEN, ...).
  23 * 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.
  24
  25 VERSION 1.3 TODO (Virtual memory)
  26 =================================
  27
  28 * Redis Virtual Memory for datasets bigger than RAM (http://groups.google.com/group/redis-db/msg/752997c7b38553cd)
  29
  30 VERSION 1.4 TODO (Fault tollerant sharding)
  31 ===========================================
  32
  33 * Redis-cluster, a fast intermediate layer (proxy) that implements consistent hashing and fault tollerant nodes handling.
  34

  38
  39 VERSION 1.5 TODO (Optimizations and latency)
  40 ============================================
  41
  42 * Lower the CPU usage.
  43 * Lower the RAM usage everywhere possible.
  44 * Use epool and alike to rewrite ae.c for Linux and other platforms suppporting fater-than-select() mutiplexing APIs.
  45 * Implement an UDP interface for low-latency GET/SET operations.
  46
  47 SHORT/LONG TERM RANDOM TODO ITEMS
  48 =================================
  49
  50  * SORT: Don't copy the list into a vector when BY argument is constant.
  51  * 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.
  52  * LOCK / TRYLOCK / UNLOCK as described many times in the google group
  53  * Replication automated tests
  54  * BYTEDARRAY type
  55  * 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.
  56  * Read-only mode.
