             Summary: New optimized DistributedQueue implementation for overseer
                 Key: SOLR-6760
                 URL: https://issues.apache.org/jira/browse/SOLR-6760
             Project: Solr
          Issue Type: Bug
            Reporter: Noble Paul
            Assignee: Noble Paul


Currently the DQ works as follows

* read all items in the directory
* sort them all 
* take the head and return it

This works well when we have only a handful of items in the Queue. If the items in the queue is much larger in tens of thousands, this is counterprodcutive

As the overseer queue is a multiple producers + single consumer queue, We can read them all in bulk  and before processing each item , just do a zk.exists(itemname) and if all is well we don't need to do the fetch all + sort thing again
