Subject [GitHub] incubator-quickstep issue #14: QUICKSTEP-8: Long running Foreman thread

Github user hbdeshmukh commented on the issue:

    > @hbdeshmukh Have you try to use std::vector<const QueryHandle*> instead of
std::vector<QueryHandle*>?
    
    Using ``const QueryHandle*`` doesn't work because we extract the DAG from it. On the DAG
pointer, we call ``getNodePayloadMutable()`` to fetch a pointer to the ``RelationalOperator``.
The function ``getAllWorkOrders`` changes the state of the DAG. Due to this chain, we can't
use ``const QueryHandle*``.
