Status

Current state: "Under Discussion"

Discussion thread: here

JIRA: KAFKA-313

Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

Add JSON/CSV output and looping options to ConsumerGroupCommand. Neither of the these options depend on each other (you can loop in the human readable output, or do a single shot execution with JSON output). Existing behavior/output maintained if neither of the the options are used.

Public Interfaces

Add the following two options to the ConsumerGroupCommand:

• output.format, if specified, takes "csv" or "json" as value, sets the output format of ConsumerGroupCommand to "csv" or "json"

• loop, if specified, takes an integer value greater than 0, keeps executing the command at an interval of that many seconds until explicitly terminated by the admin/user

Proposed Changes

Add JSON/CSV output and looping options to ConsumerGroupCommand. Neither of the these options depend on each other (you can loop in the human readable output, or do a single shot execution with JSON output). Existing behavior/output maintained if neither of the the options are used.

 Adds following two options to ConsumerGroupCommand.
