--------------------------------
> [M1] Merge DatabricksSqlParser with SparkSqlParser
> --------------------------------------------------
>
> Key: SPARK-48579
> URL: https://issues.apache.org/jira/browse/SPARK-48579
> Project: Spark
> Issue Type: Sub-task
> Reporter: David Milicevic
> Priority: Major
>
> OSS has single parser for SQL statements - SparkSqlParser.
> However, in runtime we have additional parser - DatabricksSqlParser. This
> parser is used for edge SQL rules, but there is no clear separation because
> folks keep adding edge rules/features to the SparkSqlParser as well.
> More details can be found in this design doc comment:
> [https://docs.google.com/document/d/1DIsMf2LQJvD4UC5JR1-YBH6Rv3UvGK3dD2QTOf_0SK4/edit?disco=AAABNCpDpdo.|https://docs.google.com/document/d/1DIsMf2LQJvD4UC5JR1-YBH6Rv3UvGK3dD2QTOf_0SK4/edit?disco=AAABNCpDpdo]

> It seems like there is no reason not to merge these two parsers into one, but
> it needs to be investigated first before refactoring.
