Class StreamExecDropUpdateBefore

java.lang.Object

org.apache.flink.table.planner.plan.nodes.exec.ExecNodeBase<RowData>

org.apache.flink.table.planner.plan.nodes.exec.stream.StreamExecDropUpdateBefore

All Implemented Interfaces:

public class StreamExecDropUpdateBefore
extends ExecNodeBase<RowData>
implements StreamExecNode<RowData>, SingleTransformationTranslator<RowData>

Stream ExecNode which will drop the UPDATE_BEFORE messages. This is usually used as an optimization for the downstream operators that doesn't need the UPDATE_BEFORE messages, but the upstream operator can't drop it by itself (e.g. the source).

Description copied from class: ExecNodeBase

Internal method, translates this node into a Flink operator.

Specified by:

translateToPlanInternal in class ExecNodeBase<RowData>

Parameters:

planner - The planner.

config - per-ExecNode configuration that contains the merged configuration from various layers which all the nodes implementing this method should use, instead of retrieving configuration from the planner. For more details check ExecNodeConfig.
