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, ... +* Write docs for the "STORE" operaiton of SORT. Link to the article about SORT by written by defunkt. +* ZRANGEBYSCORE LIMIT option and test. + +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 1.6 TODO (Virtual memory) +================================= + +* Redis Virtual Memory for datasets bigger than RAM (http://groups.google.com/group/redis-db/msg/752997c7b38553cd) + +VERSION 1.8 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 2.0 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. + +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 + * 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. + * Read-only mode.
