| | 1 | Redis TODO and Roadmap |
| | 2 | ---------------------- |
| | 3 | |
| | 4 | VERSION 2.2 TODO (Optimizations and latency) |
| | 5 | ============================================ |
| | 6 | |
| | 7 | * Support for syslog(3). |
| | 8 | * Change the implementation of ZCOUNT to use the augmented skiplist in order to be much faster. |
| | 9 | |
| | 10 | VM TODO |
| | 11 | ======= |
| | 12 | |
| | 13 | * Use multiple open FDs against the VM file, one for thread. |
| | 14 | * 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. |
| | 15 | |
| | 16 | STRING COMMANDS |
| | 17 | =============== |
| | 18 | |
| | 19 | * Implement STRLEN, PEEK, POKE, SETBIT, GETBIT |
| | 20 | |
| | 21 | OTHER IMPORTANT THINGS THAT WILL BE ADDED BUT I'M NOT SURE WHEN |
| | 22 | =============================================================== |
| | 23 | |
| | 24 | BIG ONES: |
| | 25 | |
| | 26 | * BRPOPLPUSH |
| | 27 | * Specially encoded memory-saving integer sets. |
| | 28 | * A command to export a JSON dump (there should be mostly working patch needing major reworking). |
| | 29 | * Specially encoded sets of integers (this includes a big refactoring providing an higher level layer for Sets manipulation) |
| | 30 | |
| | 31 | SMALL ONES: |
| | 32 | |
| | 33 | * 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. |
| | 34 | * Delete on writes against expire policy should only happen after argument parsing for commands doing their own arg parsing stuff. |
| | 35 | * 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. |
| | 36 | * MSADD (n keys) (n values). See this thread in the Redis google group: http://groups.google.com/group/redis-db/browse_thread/thread/e766d84eb375cd41 |
| | 37 | * Don't save empty lists / sets / zsets on disk with snapshotting. |
| | 38 | * Remove keys when a list / set / zset reaches length of 0. |
| | 39 | * 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. |
| | 40 | * PING the master from time to time to check if it's gone. |
| | 41 | |
| | 42 | THE "MAYBE" TODO LIST: things that may or may not get implemented |
| | 43 | ================================================================= |
| | 44 | |
| | 45 | Most of this can be seen just as proposals, the fact they are in this list |
| | 46 | it's not a guarantee they'll ever get implemented ;) |
| | 47 | |
| | 48 | * SORT: Don't copy the list into a vector when BY argument is constant. |
| | 49 | * 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. |
| | 50 | * 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. |
| | 51 | * Read-only mode. |
| | 52 | * Kill the delete-on-write behavior of expires, replicating DELs |
| | 53 | * Multiple BY in SORT. |
| | 54 | |
| | 55 | KNOWN BUGS |
| | 56 | ========== |
| | 57 | |
| | 58 | * 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. |
