L. C. Hsieh created SPARK-36797: ----------------------------------- Summary: Union should resolve nested columns as top-level columns Key: SPARK-36797 URL: https://issues.apache.org/jira/browse/SPARK-36797 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 3.3.0 Reporter: L. C. Hsieh
Union, by definition, resolves columns by position. Currently we only follow this behavior at top-level columns, but not nested columns. As we are making nested columns as first-class citizen, the nested-column-only limitation and the difference between top-level column and nested column do not make sense. -- 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
