[jira] [Commented] (SPARK-28303) Support DELETE/UPDATE/MERGE
Operations in DataSource V2
[ https://issues.apache.org/jira/browse/SPARK-28303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16942037#comment-16942037 ]
Timothy Zhang commented on SPARK-28303:
---------------------------------------
I just found this issue. Here is the issue reported by me: https://issues.apache.org/jira/browse/SPARK-29185. Based on my analysis on current Spark JDBC codes I found it is easy to extend to support DELETE/UPDATE/MERGE just enhance SaveMode and add some statements of DELETE/UPDATE/MERGE. Would you please look at the issue 29185?
> Support DELETE/UPDATE/MERGE Operations in DataSource V2
> -------------------------------------------------------
>
> Key: SPARK-28303
> URL: https://issues.apache.org/jira/browse/SPARK-28303
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Xianyin Xin
> Priority: Major
>
> Now many datasources (delta, jdbc, hive with transaction support, kudu, etc) supports deleting/updating data. It's necessary to add related APIs in the datasource V2 API sets.
> For example, we suggest add the below interface in V2 API,
> {code:java|title=SupportsDelete.java|borderStyle=solid}
> public interface SupportsDelete {
> WriteBuilder delete(Filter[] filters);
> }
> {code}
> which can delete data by simple predicates (complicated cases like correlated subquery is not considered currently).
