Class SinkModifyOperation

java.lang.Object

org.apache.flink.table.operations.SinkModifyOperation

All Implemented Interfaces:

ModifyOperation, Operation

Direct Known Subclasses:

DeleteFromFilterOperation, StagedSinkModifyOperation

@Internal
public class SinkModifyOperation
extends Object
implements ModifyOperation

DML operation that tells to write to a sink.

The sink is described by getContextResolvedTable(), and in general is used for every sink which implementation is defined with DynamicTableSink. DataStream and TableResult.collect() sinks are handled by respectively ExternalModifyOperation and CollectModifyOperation.
