public static final class Mpp.MPPDataPacket
extends com.google.protobuf.GeneratedMessageV3
implements Mpp.MPPDataPacketOrBuilder

 when TiFlash sends data to TiDB, Data packets wrap tipb.SelectResponse, i.e., serialize tipb.SelectResponse into data;
 when TiFlash sends data to TiFlash, data blocks are serialized into chunks, and the execution_summaries in tipb.SelectResponse are serialized into data only for the last packet.
