Qifan Chen has uploaded a new patch set (#9). ( http://gerrit.cloudera.org:8080/16720 )
Change subject: [WIP] IMPALA-10325 Parquet scan should use min/max statistics to skip pages based on equi-join predicate ...................................................................... [WIP] IMPALA-10325 Parquet scan should use min/max statistics to skip pages based on equi-join predicate This patch adds the logic to utilize min/max stats for Parquet row groups or pages to skip these entities when they don't qualify an equi-join predicate. A new class of predicates called overlap predicates is introduced to aid in the determination of whether a Parquet row group or a page overlap with the a range computed from the hash join. If not, then the entire Parquet row group or the page are skipped. The new class of predicates co-exist with the existing min/max conjuncts that are introduced based on the local scan predicates. Both classes of predicates can work individually or togther with each other.
