            Before Fix of MB-20053-
            Each Bulk Fetch from data node uses it’s own worker thread.
            After the Fix Bulk Fetch from data node is serviced by N-worker threads. N = 2.5*CPU’s . All the N1QL fetch from data nodes are serviced by the worker threads.

            Regards,
            Sitaram
