--------------------------------------

             Summary: Offsets clean up based on largest Timestamp in a Log segment
                 Key: KAFKA-13085
                 URL: https://issues.apache.org/jira/browse/KAFKA-13085
             Project: Kafka
          Issue Type: Bug
          Components: config
            Reporter: Mohamed Aashif


This is to confirm the behaviour of [retention.ms|https://kafka.apache.org/documentation/#topicconfigs_retention.ms].

According to the kafka doc, a log segment is kept undeleted until the *_Largest timestamp_* of the offsets in that segment.

Initially, we thought that the _*Largest timestamp*_ is the considered from the created time of the record. But, it is considered from the timestamp of the _ProducerRecord_, which can be entered manually.

We suspect if this is intentional, as the log segment can be undeleted forever if the timestamp of a far future time is given.

Please clarify.
