-----------------------------------
Summary: 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: 2.4.3
Reporter: Xianyin Xin
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,
```java
public interface SupportsDelete extends WriteBuilder {
WriteBuilder delete(Filter[] filters);
}
```
which can delete data by simple predicates (complicated cases like correlated
subquery is not considered currently).
