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