Gengliang Wang created SPARK-28589: -------------------------------------- Summary: Follow the type conversion rules of PostgreSQL Key: SPARK-28589 URL: https://issues.apache.org/jira/browse/SPARK-28589 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 3.0.0 Reporter: Gengliang Wang Attachments: type_conversion.txt
The type conversion in current Spark can be improved by learning from PostgreSQL: 1. The table insertion should disallow certain type conversions(string -> int), see https://docs.google.com/document/d/1b9nnWWbKVDRp7lpzhQS1buv1_lDzWIZY2ApFs5rBcGI/edit#heading=h.82w8qxfl2uwl 2. Spark should return null result on cast an out-of-range value to an integral type, instead of returning a value with lower bits. 3. We can have a new optional mode: throw runtime exceptions on casting failures 4. improve the implicit casting -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
