Subject Re: KafkaIO reading from latest offset when pipeline fails on FlinkRunner
Date Wed, 10 Jan 2018 18:34:48 GMT
How often does your pipeline checkpoint/snapshot? If the failure happens
before the first checkpoint, the pipeline could restart without any state,
in which case KafkaIO would read from latest offset. There is probably some
way to verify if pipeline is restarting from a checkpoint.
