Maxim Gekk created SPARK-25252: ---------------------------------- Summary: Support arrays of any types in to_json Key: SPARK-25252 URL: https://issues.apache.org/jira/browse/SPARK-25252 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 2.3.1 Reporter: Maxim Gekk
Need to improve the to_json function and make it more consistent with from_json by supporting arrays of any types (as root types). For now, it supports only arrays of structs and arrays of maps. After the changes the following code should work: {code:scala} select to_json(array('1','2','3')) > ["1","2","3"] select to_json(array(array(1,2,3),array(4))) > [[1,2,3],[4]] {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
