Steven Hawkins commented on TEIID-2559:
---------------------------------------

min has been removed as an option as by pushing the pushdown processing to the dependentcriteriaprocessor we can reuse the logic to perform duplication removal and detect if multiple commands will be issued which triggers the pushdown.

> make dep hints should support additional options to facilitate TEIID-2249.  This includes:
> min - the minimum number of rows to trigger a dependent join full pushdown
> max - the maximum number of rows allowed before rejecting the dependent join (this would apply in both full pushdown and partial non-pushdown scenarios - in the latter though it will likely refer to the number of distinct values)
