Subject Re: allowed lateness on windowed join?
Date Mon, 06 Feb 2017 08:57:54 GMT
Hi,

Union is a super cheap operator in Flink. It does not scan the records, but
just merges the streams. So the effort is very low.
The built-in join operator works in the same way but does not expose
allowed lateness.

Cheers, Fabian
