Rick Shaw commented on CASSANDRA-3753:
--------------------------------------
This will be a very valuable feature for the clients. If it was in place it
would greatly facilitate client side error checking and argument
transformation.
_But_ I am skeptical that we can come up with a reliable method to determine
type to be returned in the "prepare" phase of the client-server exchange. The
barrier is (I think) that {{Term}} can occur on both the "left" and "right"
side so it can for instance _name_ a column. So until the column name is
actually resolved you can't determine its type.
