Subject [jira] [Updated] (KAFKA-5639) Enhance DescribeGroups protocol to include additional group information
Date Tue, 25 Jul 2017 20:28:00 GMT

     [ https://issues.apache.org/jira/browse/KAFKA-5639?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vahid Hashemian updated KAFKA-5639:
-----------------------------------
    Description: 
The [{{DescribeGroups}}|https://kafka.apache.org/protocol#The_Messages_DescribeGroups] protocol
v1 currently returns this information for each consumer group:
* {{error_code}}
* {{group_id}}
* {{state}}
* {{protocol_type}}
* {{protocol}}
* {{members}}

There are additional info in a {{GroupMetadata}} object on the server side, some of which
could be useful if exposed via the {{DescribeGroups}} protocol. Here are some examples:
* {{generationId}}
* {{leaderId}}
* {{numOffsets}}
* {{hasOffsets}}

Enhancing the protocol with this additional info means improving the existing tools that make
use of it. For example, using this additional info, the consumer group command's {{\-\-describe}}
output will provide more information about each consumer group to help with its monitoring
/ troubleshooting / ....
