Subject Re: Kafka data not read in FlinkKafkaConsumer09 second time from command line
Date Tue, 24 Jan 2017 17:04:17 GMT
Hi,
a bit more information would be useful. Are you using event-time? Is the
Flink program kept running after adding the first batch of events and when
adding the second batch or is it to invocations of your Flink program? Do
you have a custom timestamp/watermark assigner?

Cheers,
Aljoscha
