4c22fd34 4WARNING: are you a possible Redis contributor?
5 Before implementing what is listed what is listed in this file
6 please drop a message in the Redis google group or chat with
7 antirez or pietern on irc.freenode.org #redis to check if the work
8 is already in progress and if the feature is still interesting for
9 us, and *how* exactly this can be implemented to have good changes
10 of a merge. Otherwise it is probably wasted work! Thank you

4e17be0e 13API CHANGES
14===========
bb8716b6 15
4e17be0e 16* Turn commands into variadic versions when it makes sense, that is, when
17 the variable number of arguments represent values, and there is no conflict
18 with the return value of the command.

8905378c 20CLUSTER
21=======
22
23* Implement rehashing and cluster check in redis-trib.
24* Reimplement MIGRATE / RESTORE to use just in memory buffers (no disk at
25 all). This will require touching a lot of the RDB stuff around, but we may
26 hand with faster persistence for RDB.
27* Implement the slave nodes semantics and election.
28* Allow redis-trib to create a cluster-wide snapshot (using SYNC).
29* Allow redis-trib to restore a cluster-wide snapshot (implement UPLOAD?).

cc9f0eee 31APPEND ONLY FILE
32================
3f477979 33
cc9f0eee 34* in AOF rewirte use HMSET to rewrite small hashes instead of multiple calls
35 to HSET.

4c22fd34 37OPTIMIZATIONS
38=============
0188805d 39
bcde6378 40* Avoid COW due to incrementing the dict iterators counter.
682ac724 41* SORT: Don't copy the list into a vector when BY argument is constant.
42* 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.
4c22fd34 43* Read-only mode for slaves.
e9ee513b 44* Redis big lists as linked lists of small ziplists?
45 Possibly a simple heuristic that join near nodes when some node gets smaller than the low_level, and split it into two if gets bigger than high_level.

2d9fdb9d 47REPORTING
48=========
49
50* Better INFO output with sections.
51
52RANDOM
53======
54
55* Clients should be closed as far as the output buffer list is bigger than a given number of elements (configurable in redis.conf)
56* Should the redis default configuration, and the default redis.conf, just bind 127.0.0.1?
57
cef34df0 58KNOWN BUGS
59==========
60
4c22fd34 61* What happens in the following scenario:
62 1) We are reading an AOF file.
63 2) SETEX FOO 5 BAR
64 3) APPEND FOO ZAP
65 What happens if between 1 and 2 for some reason (system under huge load
66 or alike) too many time passes? We should prevent expires while the
67 AOF is loading.
8231b1ef 68* #519: Slave may have expired keys that were never read in the master (so a DEL
69 is not sent in the replication channel) but are already expired since
70 a lot of time. Maybe after a given delay that is undoubltly greater than
71 the replication link latency we should expire this key on the slave on
72 access?

4e17be0e 74DISKSTORE TODO
75==============
76
77* Fix FLUSHALL/FLUSHDB: the queue of pending reads/writes should be handled.
78* Check that 00/00 and ff/ff exist at startup, otherwise exit with error.
79* Implement sync flush option, where data is written synchronously on disk when a command is executed.
80* Implement MULTI/EXEC as transaction abstract API to diskstore.c, with transaction_start, transaction_end, and a journal to recover.
81* Stop BGSAVE thread on shutdown and any other condition where the child is killed during normal bgsave.
82* Fix RANDOMKEY to really do something interesting
83* Fix DBSIZE to really do something interesting
84* Add a DEBUG command to check if an entry is or not in memory currently
85* dscache.c near 236, kobj = createStringObject... we could use static obj.
