| | 1 | Redis TODO |

| | 4 | WARNING: 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 |

| | 13 | API CHANGES |
| | 14 | =========== |
| | 15 | |
| | 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. |
| | 19 | |
| | 20 | APPEND ONLY FILE |
| | 21 | ================ |
| | 22 | |
| | 23 | * in AOF rewirte use HMSET to rewrite small hashes instead of multiple calls |
| | 24 | to HSET. |
| | 25 | |
| | 26 | OPTIMIZATIONS |
| | 27 | ============= |
| | 28 | |
| | 29 | * Avoid COW due to incrementing the dict iterators counter. |
| | 30 | * SORT: Don't copy the list into a vector when BY argument is constant. |
| | 31 | * 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. |
| | 32 | * Read-only mode for slaves. |
| | 33 | * Redis big lists as linked lists of small ziplists? |
| | 34 | 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. |
| | 35 | |
| | 36 | REPORTING |
| | 37 | ========= |
| | 38 | |
| | 39 | * Better INFO output with sections. |
| | 40 | |
| | 41 | RANDOM |
| | 42 | ====== |
| | 43 | |
| | 44 | * Clients should be closed as far as the output buffer list is bigger than a given number of elements (configurable in redis.conf) |
| | 45 | * Should the redis default configuration, and the default redis.conf, just bind 127.0.0.1? |
| | 46 | |
| | 47 | KNOWN BUGS |
| | 48 | ========== |
| | 49 | |
| | 50 | * What happens in the following scenario: |
| | 51 | 1) We are reading an AOF file. |
| | 52 | 2) SETEX FOO 5 BAR |
| | 53 | 3) APPEND FOO ZAP |
| | 54 | What happens if between 1 and 2 for some reason (system under huge load |
| | 55 | or alike) too many time passes? We should prevent expires while the |
| | 56 | AOF is loading. |
| | 57 | * #519: Slave may have expired keys that were never read in the master (so a DEL |
| | 58 | is not sent in the replication channel) but are already expired since |
| | 59 | a lot of time. Maybe after a given delay that is undoubltly greater than |
| | 60 | the replication link latency we should expire this key on the slave on |
| | 61 | access? |
| | 62 | |
| | 63 | DISKSTORE TODO |
| | 64 | ============== |
| | 65 | |
| | 66 | * Fix FLUSHALL/FLUSHDB: the queue of pending reads/writes should be handled. |
| | 67 | * Check that 00/00 and ff/ff exist at startup, otherwise exit with error. |
| | 68 | * Implement sync flush option, where data is written synchronously on disk when a command is executed. |
| | 69 | * Implement MULTI/EXEC as transaction abstract API to diskstore.c, with transaction_start, transaction_end, and a journal to recover. |
| | 70 | * Stop BGSAVE thread on shutdown and any other condition where the child is killed during normal bgsave. |
| | 71 | * Fix RANDOMKEY to really do something interesting |
| | 72 | * Fix DBSIZE to really do something interesting |
| | 73 | * Add a DEBUG command to check if an entry is or not in memory currently |
| | 74 | * dscache.c near 236, kobj = createStringObject... we could use static obj. |
