@Override
  public PlanNode clone() {
    return new PipeEnrichedInsertNode((InsertNode) insertNode.clone());
  }
This class aims to mark the {@link InsertNode} to prevent forwarding pipe insertions. The
handling logic is defined in:

<p>1.{@link RegionWriteExecutor}, to serialize and reach the target data region.

<p>2.{@link TriggerFireVisitor}, to fire the trigger before writing to data region.

<p>3.{@link DataExecutionVisitor}, to actually write data on data region and mark it as received
from pipe.
