Ted Yu created SPARK-33915: ------------------------------ Summary: 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
Currently PushableColumnBase provides no support for json / jsonb expression. Example of json expression: get_json_object(phone, '$.code') = '1200' 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
