Hi José,
Can you see more about what you are trying to do? Unless the GroupBy
can be pushed somewhere else for the work, generally, I'd suppose that
all of the data involved has to be scanned/observed and all entire
CalcResult would effectively need to be in-memory already.
The only exception I could imagine would be if the data is coming back
sorted by the GroupBy attribute...
Cheers,
Jim

Hi,
I was wondering if it is posible to get the results from a CalcResult
object in the form of a lazy iterator instead of creating a Java List,
or Map, or Array, etc. In my case, this CalcResult is generated by a
GroupByVisitor, and I am almost sure that instantiating a List from it
will lead to memory issues. Any idea?
Thanks a lot,
José
