This is for 7.1, for the first alpha. In 7.0, we've focused on creating Hot Rod 2.0 protocol which adds a lot of enhancements and capabilities in a backwards compatible way.
In 7.1, a big focus should be on refactoring the protocol decoders for Memcached and Hot Rod which are very entangled and are hindering development of Hot Rod. Essentially, each should have a fully async decoder that focuses purely on the protocol at hand and makes the most of it.
This should also enable to improve performance of each protocol decoder.
