Qingsheng Ren commented on FLINK-24605:
---------------------------------------
Thanks for reporting this [~a_talukdar] ! I think it's a bug in the
{{KafkaDynamicSource}}. It doesn't check {{auto.offset.reset}} property when
building {{KafkaSource}} so the offset reset strategy is overwritten as "none".
I can submit a patch for this.
