------------------------------------------
> PPD: Make Floating point NaN check more strict
> ----------------------------------------------
>
> Key: ORC-683
> URL: https://issues.apache.org/jira/browse/ORC-683
> Project: ORC
> Issue Type: Improvement
> Reporter: Panagiotis Garefalakis
> Assignee: Panagiotis Garefalakis
> Priority: Minor
>
> #ORC-629 added an extra check (part of RecordReaderImp) disabling PPD when
> DoubleColumnStats min, max or sum is a non-Finite number.
> However, the check is unnecessarily broad – the way stats are updated, using
> just sum for the check would suffice.
