> When calculating offset ranges, we consider minPartitions configuration. If
> minPartitions is not set or is less than or equal the size of given ranges,
> it means there are enough partitions at Kafka so we don't need to split
> offsets to satisfy min partition requirement. But the current condition is
> offsetRanges.size > minPartitions.get and is not correct. Currently getRanges
> will split offsets in unnecessary case.
