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

             Summary: Examining log messages with {{--deep-iteration}} should show superset of fields
                 Key: KAFKA-6181
                 URL: https://issues.apache.org/jira/browse/KAFKA-6181
             Project: Kafka
          Issue Type: Improvement
          Components: core
    Affects Versions: 0.11.0.0
            Reporter: Yeva Byzek
            Priority: Minor


Printing log data on Kafka brokers using {{kafka.tools.DumpLogSegments}}:
{{--deep-iteration}} should show a superset of fields in each message, as compared to without this parameter, however some fields are missing.  Impact: users need to execute both commands to get the full set of fields.

Notice, for example, that {{partitionLeaderEpoch}} and {{crc}} are missing. Print these and all missing fields.
