> Sergi suggested that we reuse results of the same queries running simultaneously - i.e.
if a query is being executed with the same arguments and flags again and again, there's no
need to do actual querying of data, instead we can really run query once while other simultaneous
runs will wait for those results.
> This strategy will be implemented on MAP stage of distributed query.
