> Use deltastreamer to consume kafka,
>  When earliestOffsets is greater than checkpoint, Hudi will not be able to successfully consume data
> org.apache.hudi.utilities.sources.helpers.KafkaOffsetGen#checkupValidOffsets
> boolean checkpointOffsetReseter = checkpointOffsets.entrySet().stream()
>  .anyMatch(offset -> offset.getValue() < earliestOffsets.get(offset.getKey()));
> return checkpointOffsetReseter ? earliestOffsets : checkpointOffsets;
> Kafka data is continuously generated, which means that some data will continue to expire.
>  When earliestOffsets is greater than checkpoint, earliestOffsets will be taken. But at this moment, some data expired. In the end, consumption fails. This process is an endless cycle. I can understand that this design may be to avoid the loss of data, but it will lead to such a situation, I want to fix this problem, I want to hear your opinion
