Peter Szecsi updated ZOOKEEPER-3374:
------------------------------------
Description:
The {{multiRead}} operation allows us to traverse a tree using fewer requests
to the server (by using batched {{getChildren}} operations). At the moment, the
number of requests for traversal is the same as the number of nodes, however,
this can be changed to only use up as many requests as the height of the tree.
Currently, {{listSubTreeBFS}} utility function used for the {{deleteAll}}
command and this improvement makes it more robust, especially in high latency
setups.
