             Summary: GetOffsetShell: retrieve offsets for multiple topics with single request
                 Key: KAFKA-5234
                 URL: https://issues.apache.org/jira/browse/KAFKA-5234
             Project: Kafka
          Issue Type: Improvement
          Components: tools
            Reporter: Arseniy Tashoyan
             Fix For: 0.11.0.0


At present, GetOffsetShell is able to retrieve offsets for one topic only:

--topic <topic> REQUIRED: The topic to get offsets from.

If user wants to get offsets for several topics, he has to call GetOffsetShell as many times as the number of topics to explore. Some solutions may have dozens of topics. Monitoring of a large Kafka cluster with GetOffsetShell requires additional scripting efforts and produces visible performance drawback due to multiple requests to the broker.

Instead, GetOffsetShell should support multiple topics, for example:

--topics topic1,topic2,topic3

Moreover, GetOffsetShell should be able to retrieve offsets for _all_ topics, when user specified none topics in command line.
