@ -124,3 +124,19 @@ You can also provide your own solution if you wish, keyed off of ``message.reply
which is the unique channel representing the connection, but remember that
whatever you store in must be **network-transparent** - storing things in a
global variable won't work outside of development.
Would you support messagepack or any other format?
--------------------------------------------------
Although we've evaluated msgpack it does not offer enough over JSON to be
reasonable - the encoding/decoding is often slower, the language support is
much poorer, and in general we would rather just have one version of a standard,
especially since there's plans to write parts of the Channels system in other
languages.
That said, at some point it's up to the individual channel backend to support
whatever it likes, as long as it spits out dicts at either end. So this is
something that could be implemented by someone else as a pluggable backend to
see. We might always come back and revisit this if message size/bandwidth turns
out to be a limiting factor, though.
