[jira] [Created] (ZOOKEEPER-2260) Paginated getChildren call

Marco P. created ZOOKEEPER-2260:
-----------------------------------

             Summary: Paginated getChildren call
                 Key: ZOOKEEPER-2260
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2260
             Project: ZooKeeper
          Issue Type: New Feature
            Reporter: Marco P.
            Priority: Minor


Add pagination support to the getChildren() call, allowing clients to iterate over children N at the time.

Motivations for this include:
  - Getting out of a situation where so many children were created that listing them exceeded the network buffer sizes (making it impossible to recover by deleting)[1]
 - More efficient traversal of nodes with large number of children [2]

I do have a patch (for 3.4.6) we've been using successfully for a while, but I suspect much more work is needed for this to be accepted.
