---------------------------------
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.
