----------------------------------

             Summary: UltraDNS Transaction support
                 Key: JCLOUDS-43
                 URL: https://issues.apache.org/jira/browse/JCLOUDS-43
             Project: jclouds
          Issue Type: Improvement
          Components: jclouds-core
    Affects Versions: 1.6.0
            Reporter: Adrian Cole
            Assignee: Adrian Cole
             Fix For: 1.6.1


When testing the ultradns-ws provider, Netflix noticed that migrating territories from one directional group to another to results in a drop of traffic and slow recovery.  The root cause is how updates must occur considering territory overlaps are illegal.

Ex. first remove argentina from group a.  next add argentina to group b.

Advice is to wrap the two commands into a transaction, which may eliminate some traffic loss scenarios.

Implementation:

expose a TransactionApi and a corresponding scope to attribute the transaction to any write commands within it.
