-------------------------------------

             Summary: Enforce sane maximums for BATCH_SIZE
                 Key: IMPALA-5541
                 URL: https://issues.apache.org/jira/browse/IMPALA-5541
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.10.0
            Reporter: Tim Armstrong
            Priority: Minor


We don't enforce maximums on BATCH_SIZE. Setting a very large value could cause strange behaviour
like crashing, hanging, excessive memory usage, spinning etc.

I think a limit like  65536 (64x the default) would be reasonable but it's worth discussing
further.
