[jira] [Created] (SPARK-29983) Add an independent config for an optional INTERVAL clause

Takeshi Yamamuro created SPARK-29983:
----------------------------------------

             Summary: Add an independent config for an optional INTERVAL clause
                 Key: SPARK-29983
                 URL: https://issues.apache.org/jira/browse/SPARK-29983
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Takeshi Yamamuro


This pr is to add a new config only for an optional INTERVAL clause. In the master, this feature is enabled when `spark.sql.ansi.enabled`=true. This pr proposes to split off the optional interval flag from `spark.sql.ansi.enabled`. 

An optional interval is defined in the ANSI/SQL standard, but some ANSI/SQL-compatible databases don't follow this feature, e.g., PosgreSQL. So, it is useful to have an independent config for the feature.
