Jonathan Ellis resolved CASSANDRA-4240.
---------------------------------------
Resolution: Won't Fix
It's a pretty deep limitation that you can't index values larger than 64k,
because the KEYS index type turns the indexed values into row keys to look them
up. We record the size of a row key with 2 bytes, hence the limitation.
> Only check the size of indexed column values when they are of type KEYS

> That line states that: Indexed column values cannot be larger than 64K. But
> in some cases we would want the column values to be able to be larger than
> 64k, specifically if the index_type is not of type KEYS.
