Gengliang Wang created SPARK-42442: -------------------------------------- Summary: Use spark.sql.timestampType for data source inference Key: SPARK-42442 URL: https://issues.apache.org/jira/browse/SPARK-42442 Project: Spark Issue Type: Sub-task Components: SQL Affects Versions: 3.4.0 Reporter: Gengliang Wang Assignee: Gengliang Wang
With the configuration `spark.sql.timestampType`, TIMESTAMP in Spark is a user-specified alias associated with one of the TIMESTAMP_LTZ and TIMESTAMP_NTZ variations. This is quite complicated to Spark users. There is another option `spark.sql.sources.timestampNTZTypeInference.enabled` for schema inference. I would like to introduce it in [https://github.com/apache/spark/pull/40005] but having two flags seems too much. After thoughts, I decide to merge `spark.sql.sources.timestampNTZTypeInference.enabled` into `spark.sql.timestampType` and let `spark.sql.timestampType` control the schema inference behavior. We can have followups to add data source options "inferTimestampNTZType" for CSV/JSON/partiton column like JDBC data source did. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
