[jira] [Created] (KAFKA-13154) Misleading behaviour of OffsetSpec.latest()

Gabi Pi. created KAFKA-13154:
--------------------------------

             Summary: Misleading behaviour of OffsetSpec.latest()
                 Key: KAFKA-13154
                 URL: https://issues.apache.org/jira/browse/KAFKA-13154
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 2.5.1
            Reporter: Gabi Pi.


When using `OffsetSpec.latest()` to get latest offsets per partition on topic, the return result represents count of offsets in topic and not the latest offset.

For example:
 * For empty topic, the latest offset will be 0 (instead of -1, similar to `OffsetSpec.forTimestamp` method)
 * For topic with 1 message per partition, the latest returned offset will be 1 (instead of 0)

The method described in the docs in the following way:
_Used to retrieve the latest offset of a partition_

According to this description, I think that the current behaviour is misleading.
