Marco P. commented on ZOOKEEPER-2260:
-------------------------------------
The version we're using returns children sorted by ZxId, so if children can be
created and deleted while pagination is in progress.
The newly created will show up in the last page (due to creation order).
> 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
> Labels: features
>
> 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.
