Really ? I would have thought its vice versa. E.g. a float is usualy 4
(or 8) bytes in binary, but can be a lot longer in text depending on
the format.

Personally I would be interested in whether a binary protocol impl in
the JDBC driver would bring benefits or not for the other, simpler
types (int, string, ...). If they don't suffer, then it might actually
be worthwhile to investigate a binary impl. That is being said of
course from a pure user perspective - I have no insight whatsoever in
the core workings of the JDBC driver.
