This will reduce chances of introducing unintended side effects. So, instead of using the number of chunks, could we scale down the denominator until we get a non-zero estRowCount ? Also, I would be in favor of treating this as a separate jira since it was exposed by partition pruning. - Aman Sinha On March 24, 2015, 4:53 p.m., Jason Altekruse wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
