Liang-Chi Hsieh created SPARK-21990: ---------------------------------------
Summary: QueryPlanConstraints misses some constraints can be recursively inferred Key: SPARK-21990 URL: https://issues.apache.org/jira/browse/SPARK-21990 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.2.0 Reporter: Liang-Chi Hsieh When I inspected the latest change of SPARK-21979, I found we could miss few constraints that can be recursively inferred. E.g. consider constraints {{a === b && b === c && a === 1 && b === 5}}. Currently we only infer {{a === c && b === 1 && c === 5}}, but {{c === 1}} can be also inferred from newly inferred constraint {{a === c}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
