Subject [jira] [Commented] (ZOOKEEPER-2260) Paginated getChildren call

Esteban Gutierrez commented on ZOOKEEPER-2260:
----------------------------------------------

Hey [~mprime] are you still working on this? I've run into this issue a couple of times while
reading 10s of thousands of children and it would be really helpful to have some pagination
when the client can be resource limited. Thanks!

> 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.
