No TODO file here. +Please check the TODO file in the master branch on github. -VERSION 2.2 TODO (Optimizations and latency) -============================================ - -* Support for syslog(3). -* Change the implementation of ZCOUNT to use the augmented skiplist in order to be much faster. -* Add an explicit test for MULTI/EXEC reloaded in the AOF. -* Command table -> hash table, with support for command renaming - -VM TODO -======= - -* Use multiple open FDs against the VM file, one for thread. -* Check what happens performance-wise if instead of creating threads again and again the same threads are reused forever. Note: this requires a way to disable this clients in the child, but waiting for empty new jobs queue can be enough. - -STRING COMMANDS -=============== - -* Implement STRLEN, PEEK, POKE, SETBIT, GETBIT - -OTHER IMPORTANT THINGS THAT WILL BE ADDED BUT I'M NOT SURE WHEN -=============================================================== - -BIG ONES: - -* BRPOPLPUSH -* Specially encoded memory-saving integer sets. -* A command to export a JSON dump (there should be mostly working patch needing major reworking). -* Specially encoded sets of integers (this includes a big refactoring providing an higher level layer for Sets manipulation) - -SMALL ONES: - -* If sizeof(double) == sizeof(void*) we could store the double value of sorted sets directly in place of the pointer instead of allocating it in the heap. -* Delete on writes against expire policy should only happen after argument parsing for commands doing their own arg parsing stuff. -* Give errors when incrementing a key that does not look like an integer, when providing as a sorted set score something can't be parsed as a double, and so forth. -* MSADD (n keys) (n values). See this thread in the Redis google group: http://groups.google.com/group/redis-db/browse_thread/thread/e766d84eb375cd41 -* Don't save empty lists / sets / zsets on disk with snapshotting. -* Remove keys when a list / set / zset reaches length of 0. -* An option to exec a command slave-side if the master connection is lost: even cooler: if the script returns "0" the slave elects itself as master, otherwise continue trying to reconnect. -* PING the master from time to time to check if it's gone. - -THE "MAYBE" TODO LIST: things that may or may not get implemented -================================================================= - -Most of this can be seen just as proposals, the fact they are in this list -it's not a guarantee they'll ever get implemented ;) - -* 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. -* Byte Array type (BA prefixed commands): BASETBIT BAGETBIT BASETU8 U16 U32 U64 S8 S16 S32 S64, ability to atomically INCRBY all the base types. BARANGE to get a range of bytes as a bulk value, BASETRANGE to set a range of bytes. -* Read-only mode. -* Kill the delete-on-write behavior of expires, replicating DELs -* Multiple BY in SORT. - -KNOWN BUGS -========== - -* LRANGE and other commands are using 32 bit integers for ranges, and overflows are not detected. So LRANGE mylist 0 23498204823094823904823904 will have random effects. - -REDIS CLI TODO -============== - -* Computer parsable output generation -* Memoize return values so that they can be used later as arguments, like $1 + https://github.com/antirez/redis/raw/master/TODO |
