Apache Spark reassigned SPARK-32163: ------------------------------------ Assignee: Apache Spark (was: L. C. Hsieh) > Nested pruning should still work for nested column extractors of attributes > with cosmetic variations > ---------------------------------------------------------------------------------------------------- > > Key: SPARK-32163 > URL: https://issues.apache.org/jira/browse/SPARK-32163 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.0.0 > Reporter: L. C. Hsieh > Assignee: Apache Spark > Priority: Major > > If the expressions extracting nested fields have cosmetic variations like > qualifier difference, currently nested column pruning cannot work well. > For example, two attributes which are semantically the same, are referred in > a query, but the nested column extractors of them are treated differently > when we deal with nested column pruning. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
