Daniel van der Ende created SPARK-22880:
-------------------------------------------
Summary: Add option to cascade jdbc truncate if database supports
this (PostgreSQL and Oracle)
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
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.
