-BEFORE REDIS 1.0.0-rc1
-
-- What happens if the saving child gets killed instead to end normally? Handle this.
-- Make sinterstore / unionstore / sdiffstore returning the cardinality of the resulting set.
-- Add a new field as INFO output: bgsaveinprogress
-- Remove max number of args limit
-- GETSET
-- network layer stresser in test in demo, make sure to set/get random streams of data and check that what we read back is byte-by-byte the same.
-- maxclients directive
-- check 'server.dirty' everywere
-- config parameter to change the name of the DB file
-- replication automated tests
-- an external tool able to perform the 'difference' between two Redis servers. It's like 'diff', but against Redis servers, and the output is the set of commands needed to turn the first server into the second, suitable to be sent via netcat.
- $ ./redis-diff 192.168.1.1 192.168.1.2 > diff.txt
- $ cat diff.txt | nc 192.168.1.1 6379
- $ ./redis-diff 192.168.1.1 192.168.1.2
- $ # No output now the servers are identical
-
-This command should be smart and don't use too much memory, that is, take two connections at the same time against the two servers and perform the comparison key by key. Probably the initial "KEYS *" is unavoidable.
-
-- Shutdown must kill other background savings before to start saving. Otherwise the DB can get replaced by the child that rename(2) after the parent for some reason.
-- Add missing commands in documentation
-- Document replication
-- Objects sharing configuration, add the directive "objectsharingpool <size>"
-- Make sure to convert all the fstat() calls to 64bit versions.
-- SINTERCOUNT, SUNIONCOUNT, SDIFFCOUNT

-FUTURE HINTS
-
-- if in-memory values compression will be implemented, make sure to implement this so that addReply() is able to handle compressed objects, just creating an uncompressed version on the fly and adding this to the output queue instead of the original one. When insetad we need to look at the object string value (SORT BY for example), call a function that will turn the object into an uncompresed one.
+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.
