Jialin Qiao commented on IOTDB-522:
-----------------------------------
Hi, we could add two interfaces in AggregateResult:
public abstract void serializeTo(OutputStream outputStream);
public static AggregateResult deserialize(ByteBuffer buffer){};
An AggregateResult type should be added and serialized first. Then, it is used
to deserialize.
> Aggregation result should be serializable
