> I met a strange question when i use Flink SQL API.
> I found two difference type are considered equal.
> !1.png!
> After debug, i found the hashCode method and equals method in RelRecordType
> just consider "digest".
> !2.png!
> But some time, "digest" can not describe a type completely, More information
> in the "fieldList".
> !3.png!
> “digest” in TimeIndicatorRelDataType should contains time type
> information(event time or process time).
