[jira] [Updated] (KAFKA-745) Remove getShutdownReceive() and other kafka specific code from the RequestChannel

["Sriram Subramanian (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/KAFKA-745?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sriram Subramanian updated KAFKA-745:
-------------------------------------

    Attachment: KAFKA-745-v1.patch

This is a first version.

1. Removes all the metric stuff,requestObj etc from Request.
2.Adds Network metrics to track network level parameters
3. Any form of delayed request now uses a trimmed version of the Request object. 
4. Added Request metrics to the kafka layer to track kafka specific parameters

TODO - Need to add logging.
          - Some more cleanup

- We will not get all the different times for a given request as part of one log statement anymore. I think this is fine for the ability to maintain clean code.
- W.r.t the logging in the network layer, we would get info from the Request object (need to add a toString here to ignore the buffer) and nothing from the actual request. I think this is fine since knowing the request type is not useful at this layer based on the explanation above.
