CHEN Zhongpu updated FLINK-31174:
---------------------------------
    Description: 
The data format specified in 
[flink-training-repo|[https://github.com/apache/flink-training/tree/release-1.16]]
 shows that a TaixRide is either a start or an end one with the 
eventTime[.|http://example.com].]

However, the Java code in [Data Pipelines & 
ETL|[https://nightlies.apache.org/flink/flink-docs-release-1.16/docs/learn-flink/etl/]]
  tried to get both "startTime" and "endTime". But in fact, those are not 
defined in flink-training-repo.
{code:java}
Interval rideInterval = new Interval(ride.startTime, ride.endTime); {code}
I think such inconsistency would puzzle new comers of Flink.
