Subject Re: column metadata and sstable

AFAIK it just makes it easier for client API's to understand what data type to use. e.g. it
can give your code a long rather than a str / byte array . 

Personally I'm on the fence about using it. It has some advantages to the client, but given
the server does not really need the information it feels a little like additional coupling
that's not needed .
