David Mollitor created HIVE-24566: ------------------------------------- Summary: Add Parquet Stats Optimization Key: HIVE-24566 URL: https://issues.apache.org/jira/browse/HIVE-24566 Project: Hive Issue Type: Improvement Reporter: David Mollitor
Parquet files store min/max/count data in foot metadata. When a query is submitted to a Parquet table, and stats are not available, Hive should launch a single multi-threaded processor that simply reads the meta data of each Parquet file instead of walking through every single record in the table. -- This message was sent by Atlassian Jira (v8.3.4#803005)
