Tzu-Li (Gordon) Tai commented on FLINK-6062:
--------------------------------------------
The Kafka connector now allows setting to start reading at the most earliest
event, independently of any committed offsets.
However, you'll have to restart the job to do that.
I wonder if the case you mentioned here can be simply done be restarting the
job with the start position appropriately set.
What do you think [~jpreisner]?
