Cao Manh Dat commented on SOLR-10619:
-------------------------------------
Yeah, that's the reason why I added a flag ( single-consumer ) to the class.
It's much easier to optimize if we know how DQ is used.
But in case of single-consumer, the event of a node not exist is kinda rare (
right? ), if option 2 is more general, we should go with option 2?
> When DQ.knowChildren is not empty, DQ should not refetch node children in
> case of single consumer
