[jira] [Updated] (SPARK-29807) Rename "spark.sql.ansi.enabled" to
"spark.sql.dialect.spark.ansi.enabled"
[ https://issues.apache.org/jira/browse/SPARK-29807?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yuanjian Li updated SPARK-29807:
--------------------------------
Description:
The relation between "spark.sql.ansi.enabled" and "spark.sql.dialect" is confusing, since the "PostgreSQL" dialect should contain the features of "spark.sql.ansi.enabled".
To make things clearer, we can rename the "spark.sql.ansi.enabled" to "spark.sql.dialect.spark.ansi.enabled", thus the option "spark.sql.dialect.spark.ansi.enabled" is only for Spark dialect.
For the casting and arithmetic operations, runtime exceptions should be thrown if "spark.sql.dialect" is "spark" and "spark.sql.dialect.spark.ansi.enabled" is true or "spark.sql.dialect" is PostgresSQL.
