Bridget Bevens updated DRILL-6331: ---------------------------------- Labels: doc-complete ready-to-commit (was: doc-impacting ready-to-commit) > Parquet filter pushdown does not support the native hive reader > --------------------------------------------------------------- > > Key: DRILL-6331 > URL: https://issues.apache.org/jira/browse/DRILL-6331 > Project: Apache Drill > Issue Type: Improvement > Components: Storage - Hive > Affects Versions: 1.13.0 > Reporter: Arina Ielchiieva > Assignee: Arina Ielchiieva > Priority: Major > Labels: doc-complete, ready-to-commit > Fix For: 1.14.0 > > > Initially HiveDrillNativeParquetGroupScan was based mainly on HiveScan, the > core difference between them was > that HiveDrillNativeParquetScanBatchCreator was creating ParquetRecordReader > instead of HiveReader. > This allowed to read Hive parquet files using Drill native parquet reader but > did not expose Hive data to Drill optimizations. > For example, filter push down, limit push down, count to direct scan > optimizations. > Hive code had to be refactored to use the same interfaces as > ParquestGroupScan in order to be exposed to such optimizations. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
