   4 WARNING: are you a possible Redis contributor?
   5          Before implementing 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 CLUSTER
  14 =======
  15
  16 * Implement rehashing and cluster check in redis-trib.
  17 * Reimplement MIGRATE / RESTORE to use just in memory buffers (no disk at
  18   all). This will require touching a lot of the RDB stuff around, but we may
  19   hand with faster persistence for RDB.
  20 * Implement the slave nodes semantics and election.
  21 * Allow redis-trib to create a cluster-wide snapshot (using SYNC).
  22 * Allow redis-trib to restore a cluster-wide snapshot (implement UPLOAD?).
  23
  24 SCRIPTING
  25 =========
  26
  27 * SCRIPT FLUSH or alike to start a fresh interpreter?
  28
  29 OPTIMIZATIONS
  30 =============
  31
  32 * SORT: Don't copy the list into a vector when BY argument is constant.
  33 * 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.
  34 * Read-only mode for slaves.
  35 * Redis big lists as linked lists of small ziplists?
  36   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.

  38 KNOWN BUGS
  39 ==========
  40
  41 * #519: Slave may have expired keys that were never read in the master (so a DEL
  42   is not sent in the replication channel) but are already expired since
  43   a lot of time. Maybe after a given delay that is undoubtably greater than
  44   the replication link latency we should expire this key on the slave on
  45   access?
