Subject Re: Kafka streams - Large time windows ?
Date Thu, 30 Mar 2017 22:11:08 GMT
I don't see any problem with this.

You might want to increase window retention time though. It's configures
for each window individually (default is 1 day IIRC).

You set this via `.until()` when you define a window in your code.
