Cao Manh Dat updated SOLR-10619:
--------------------------------
    Attachment: SOLR-10619.patch

Updated patch for this ticket. In this patch, {{firstChild()}} will always return from cache
first, if the node is not exist, the callers of {{firstChild()}} will clear the cache and
recall {{firstChild()}}

> When DQ.knowChildren is not empty, DQ should not refetch node children in case of single
consumer

> Right now, for every time childWatcher is kicked off. We refetch all children of DQ's
node. It is a wasted in case of single consumer.
