-----------------------------------
[~Gengliang.Wang] Is this already solved by [https://github.com/apache/spark/pull/25997] ?
> New optional mode: throw runtime exceptions on casting failures
> ---------------------------------------------------------------
>
> Key: SPARK-28512
> URL: https://issues.apache.org/jira/browse/SPARK-28512
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Gengliang Wang
> Priority: Major
>
> In popular DBMS like MySQL/PostgreSQL/Oracle, runtime exceptions are thrown on casting,
e.g. cast('abc' as boolean)
> While in Spark, the result is converted as null silently. It is by design since we don't
want a long-running job aborted by some casting failure. But there are scenarios that users
want to make sure all the data conversion are correct, like the way they use MySQL/PostgreSQL/Oracle.
> This one has a bigger scope than https://issues.apache.org/jira/browse/SPARK-28741
