Brandon Williams commented on CASSANDRA-4383:
---------------------------------------------
bq. If I follow you, we'll still need to ensure that all of the legacy bits
continue to decode properly as UTF8, yes? Isn't that just relocating the
problem?
If we promote HOST_ID and TOKENS we can do whatever we like there. I guess
we'll just start accepting bytes in VV for those methods since there's no need
to mess with the others.

> Since after CASSANDRA-4317 we can know which version a remote node is using
> (that is, whether it is vnode-aware or not) this a good opportunity to change
> the token encoding to binary, since with a default of 256 tokens per node
> even a fixed-length 16 byte encoding per token provides a great deal of
> savings in gossip traffic over a text representation.
