   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

  12 DISKSTORE TODO
  13 ==============
  14
  15 * Fix FLUSHALL/FLUSHDB: the queue of pending reads/writes should be handled.
  16 * Check that 00/00 and ff/ff exist at startup, otherwise exit with error.
  17 * Implement sync flush option, where data is written synchronously on disk when a command is executed.
  18 * Implement MULTI/EXEC as transaction abstract API to diskstore.c, with transaction_start, transaction_end, and a journal to recover.
  19 * Stop BGSAVE thread on shutdown and any other condition where the child is killed during normal bgsave.
  20 * Fix RANDOMKEY to really do something interesting
  21 * Fix DBSIZE to really do something interesting
  22 * Add a DEBUG command to check if an entry is or not in memory currently
  23
  24 * dscache.c near 236, kobj = createStringObject... we could use static obj.
  25
  26 APPEND ONLY FILE
  27 ================
  28
  29 * in AOF rewirte use HMSET to rewrite small hashes instead of multiple calls
  30   to HSET.
  31
  32 OPTIMIZATIONS
  33 =============
  34
  35 * Avoid COW due to incrementing the dict iterators counter.
  36 * SORT: Don't copy the list into a vector when BY argument is constant.
  37 * 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.
  38 * Read-only mode for slaves.
  39 * Redis big lists as linked lists of small ziplists?
  40   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.
  41
  42 REPORTING
  43 =========
  44
  45 * Better INFO output with sections.
  46
  47 RANDOM
  48 ======
  49
  50 * Clients should be closed as far as the output buffer list is bigger than a given number of elements (configurable in redis.conf)
  51 * Should the redis default configuration, and the default redis.conf, just bind 127.0.0.1?
  52
  53 KNOWN BUGS
  54 ==========
  55
  56 * What happens in the following scenario:
  57     1) We are reading an AOF file.
  58     2) SETEX FOO 5 BAR
  59     3) APPEND FOO ZAP
  60     What happens if between 1 and 2 for some reason (system under huge load
  61     or alike) too many time passes? We should prevent expires while the
  62     AOF is loading.
