Mike Matrigali commented on DERBY-5235:
---------------------------------------
Given that varchar's will read into memory I am pretty sure almost nothing in
the system will work with an actual varchar that is
java.lang.Integer.MAX_VALUE. Something is going to run out of memory and
crash. Especially given Knut's note that in worst case
we are likely to be trying to allocate an array that is 3 *
java.lang.Integer.MAX_VALUE .
> Remove the artificial limit on the length of VARCHAR values, allowing them to
> be java.lang.Integer.MAX_VALUE long

> The original Cloudscape limit for the length of VARCHAR values was
> java.lang.Integer.MAX_VALUE. That is the limit in Cloudscape 5.1. Nothing in
> Derby should break if we restore the original limit. The current limit is an
> artificial bound introduced to make Derby agree with DB2. 32672 is the upper
> bound on the length of a DB2 VARCHAR:
