Flink DataStream: A few dates are getting through very slowly

Hi,

I'm using a simply streaming app with processing time and without states.
The app read from kafka, transform the data and write the data to the
storage (redis).
But I see an interesting behavior, a few dates are getting through very
slowly.
Do you have any idea why this could be?

Best,

Marke

Hi Marke,

what is the expected behaviour in your case? Is the throughput to slow or
do you expect that no elements should be output?

Cheers,
Till
