> Key: SPARK-22880
> URL: https://issues.apache.org/jira/browse/SPARK-22880
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 2.2.1
> Reporter: Daniel van der Ende
> Priority: Minor
>
> When truncating tables, PostgreSQL and Oracle support an option `TRUNCATE`.
> This cascades the truncate to tables with foreign key constraints on a column
> in the table specified to truncate. It would be nice to be able to optionally
> set this `TRUNCATE` option for PostgreSQL and Oracle.
