Subject Union/append performance question
Date Mon, 07 Sep 2015 12:56:51 GMT
Hi to all,
I have a job where I have to incrementally add Tuples to a dataset (in a
while loop).
Is union() the best operator for this task or is there a more performant
operator for this task?
Does union affect the read of already existing elements or it just appends
the new ones somewhere?
