Subject [jira] Created: (ZOOKEEPER-920) L7 (application layer) ping support
Date Mon, 08 Nov 2010 07:54:09 GMT
L7 (application layer) ping support
-----------------------------------

                 Key: ZOOKEEPER-920
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-920
             Project: Zookeeper
          Issue Type: New Feature
          Components: c client
    Affects Versions: 3.3.1
            Reporter: Chang Song
            Priority: Minor


Zookeeper is used in applications where fault tolerance is important. Its client i/o thread
send/recv heartbeats to/fro Zookeeper ensemble to stay connected. However healthy heartbeat
does not always means that the application that uses Zookeeper client is in good health, it
only means that ZK client thread is in good health.

This I needed something that can tagged onto Zookeeper ping that represents L7 (application)
health as well.
I have modified C client source to support this in minimal way. I am new to Zookeeper, so
please code review this code.  I am actually using this code in our in-house solution.

Thank you very much.
