Ted Yu updated SPARK-33915: --------------------------- Comment: was deleted (was: Opened https://github.com/apache/spark/pull/30984) > Allow json expression to be pushable column > ------------------------------------------- > > Key: SPARK-33915 > URL: https://issues.apache.org/jira/browse/SPARK-33915 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 3.0.1 > Reporter: Ted Yu > Assignee: Apache Spark > Priority: Major > > Currently PushableColumnBase provides no support for json / jsonb expression. > Example of json expression: > {code} > get_json_object(phone, '$.code') = '1200' > {code} > If non-string literal is part of the expression, the presence of cast() would > complicate the situation. > Implication is that implementation of SupportsPushDownFilters doesn't have a > chance to perform pushdown even if third party DB engine supports json > expression pushdown. > This issue is for discussion and implementation of Spark core changes which > would allow json expression to be recognized as pushable column. -- 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
