Hi Timo,

Yest. I have checked that, they are the same thing in the concept from the
documentation[1][2].
>From the desciption of the umbrella issue [FLINK-8478] of DataStream
interval join, we can also find that they are the same:

> The goal is to implement a DataStream API to join together two streams
based on a key and user defined time boundaries.

AND o.rowtime BETWEEN s.rowtime AND s.rowtime + INTERVAL '1' HOUR;

Best,
