      Description

      Looks like the bug FLINK-5479 is entirely preventing FlinkKafkaConsumerBase#assignTimestampsAndWatermarks to be used if there are any idle partitions. It would be nice to mention in documentation that currently this requires all subscribed partitions to have a constant stream of data with growing timestamps. When watermark gets stalled on an idle partition it blocks everything.
