             Summary: kafka-dump-log.sh to support dumping only head or tail part
                 Key: KAFKA-9728
                 URL: https://issues.apache.org/jira/browse/KAFKA-9728
             Project: Kafka
          Issue Type: New Feature
          Components: tools
            Reporter: Weichu Liu


When I use {{kafka-dump-log.sh}} to dump a .log file, its behavior is to traverse through
the whole file which is quite heavy.

Even with {{| head}}, the tool will still read through the whole file.

In many cases I just want to inspect the first several messages or last several messages of
a log file.

It will be great to have {{kafka-dump-log.sh}} to add options support partial reading.
