[jira] [Created] (HELIX-268) Atomic API

Kanak Biscuitwala created HELIX-268:
---------------------------------------

             Summary: Atomic API
                 Key: HELIX-268
                 URL: https://issues.apache.org/jira/browse/HELIX-268
             Project: Apache Helix
          Issue Type: Sub-task
            Reporter: Kanak Biscuitwala
            Assignee: Kanak Biscuitwala


We need to support doing logical admin operations atomically. In the past, we assumed that admin operations would typically be manual, but in practice this hasn't always been the case.

Common use cases:
- simultaneous cluster setup with one winner
- compare-and-swap style of updates
