> Add canDeleteWhere to SupportsDelete
> ------------------------------------
>
> Key: SPARK-33623
> URL: https://issues.apache.org/jira/browse/SPARK-33623
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Anton Okolnychyi
> Assignee: Anton Okolnychyi
> Priority: Major
>
> The only way to support delete statements right now is to implement
> \{{SupportsDelete}}. According to its Javadoc, that interface is meant for
> cases when we can delete data without much effort (e.g. like deleting a
> complete partition in a Hive table). It is clear we need a more sophisticated
> API for row-level deletes. That's why it would be beneficial to add a method
> to \{{SupportsDelete}} so that Spark can check if a source can easily delete
> data with just having filters or it will need a full rewrite later on. This
> way, we have more control in the future.
