Subject [jira] [Created] (IMPALA-5541) Enforce sane maximums for BATCH_SIZE
Date Tue, 20 Jun 2017 17:18:00 GMT
Tim Armstrong created IMPALA-5541:

             Summary: Enforce sane maximums for BATCH_SIZE
                 Key: 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
