Hello Flink Experts.
We have Flink job consuming data from Kafka and ingest it to multi-site
(Azure-east – Azure-west) replicated Cassandra.
Now we have to aggregate data hourly. The problem is that device X can report
once on site A and once on site B. This means that some messages for that

Hi all.
I have streaming job that reads from Kafka 0.10 manipulates data and write to
Cassandra (Tuple18)
Also this job has window and CustomReducer class involved to reduce data.
If groupedBy_windowed_stream DataStream defined with 9 fields (Tuple9)
compilation takes 5 seconds.
In current (Tuple
ectors and libraries
in the proper scope.
If you use one of the newer Flink quickstart projects, this should
automatically happen.
Best,
Stephan
