VERSION 1.1 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: * For now only the last argument gets integer encoded, so make sure that: 1) every multi bulk commands 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". * Man pages for MSET MSETNX and 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. * Support for epool in ae.c. VERSION 1.2 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) ================================= * Redis Virtual Memory for datasets bigger than RAM (http://groups.google.com/group/redis-db/msg/752997c7b38553cd) VERSION 1.4 TODO (Fault tollerant sharding) =========================================== * Redis-cluster, a fast intermediate layer (proxy) that implements consistent hashing and fault tollerant nodes handling. Interesting readings about this: - http://ayende.com/Blog/archive/2009/04/06/designing-rhino-dht-a-fault-tolerant-dynamically-distributed-hash.aspx VERSION 1.5 TODO (Optimizations and latency) ============================================ * Lower the CPU usage. * Lower the RAM usage everywhere possible. * 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. SHORT/LONG TERM RANDOM TODO ITEMS ================================= * 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 * Replication automated tests * BYTEDARRAY type * 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.
