Memcached
is cool, KISS and powerful. After no-new-release-silence
of months, I’m always expecting some new feature from it. Here are
things I’m looking forward:

• 64 bit counter: patch available from Evan Miller
• APPEND: patch available from Filipe Laborde
• Binary wire protocol: patch and python/java client code available from Dustin Sallings
• Atomic operation: patch available from Chris Goffinet
• Mass deletion: have not seen the patch yet, but I believe it will not take too long…
• Replication? Sounds cool, but a bit complex and not so useful IMHO.
• Storage backend? Useful in certain cases, but not so necessary since we have Tugela and
  NMDB
  . Ofcoz the world will be more perfect if author of NMDB make a memcached-compatible interface.
• Iterating keys/items? Useful or not? Certainly leads to abusing.

For all memcached lovers, we should give our thanks to Facebook, who contributes patches and hosts hackathon.
