/**
 * 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.
