All Implemented Interfaces:

ModifyOperation, Operation

@Internal
public class StagedSinkModifyOperation
extends SinkModifyOperation

DML operation that tells to write to a sink which implements SupportsStaging. Currently. this operation is for CTAS(CREATE TABLE AS SELECT) and RTAS([CREATE OR] REPLACE TABLE AS SELECT) statement.

StagedSinkModifyOperation is an extension of SinkModifyOperation in the atomic CTAS/RTAS scenario. Whiling checking whether the corresponding sink support atomic CTAS/RTAS or not, we will need to get DynamicTableSink firstly and check whether it implements SupportsStaging and then call the method SupportsStaging.applyStaging(org.apache.flink.table.connector.sink.abilities.SupportsStaging.StagingContext). We maintain the DynamicTableSink in this operation so that we can reuse this DynamicTableSink instead of creating a new DynamicTableSink during translating the operation again which is error-prone.
