Jackie-Jiang opened a new pull request #3535: Optimize all filter predicates by adding isAlwaysTrue()
URL: https://github.com/apache/incubator-pinot/pull/3535
 
 
   When filter predicate is always evaluated to true, we can optimize the filter operator by replacing it with MatchAllFilterOperator.
   This is especially useful for range filters on time column which spans a very long time range.
   Also added method isResultMatchingAll() in BaseFilterOperator for the optimization.
