I was googling and reading Kafka documentation but I couldn't find out the max value of a consumer offset and whether there is offset wraparound after max value. I understand offset is an Int64 value so max value is 0xFFFFFFFFFFFFFFFF. If there is wraparound, how does Kafka handle this situation? According to this post , the offset is not reset: We don't roll back offset at this moment. Since the offset is a long, it can last for a really long time. If you write 1TB a day, you can keep going for about 4 million days. Plus, you can always use more partitions (each partition has its own offset).
