return with a single hit, or N hits, with a flag of whether more hits are available or
not.
This is about decoupling the sending of a query and retrieving hits. E.g.,
RunQueryCommand <-- asks remote nodes to run a query. Request contains a unique query
ID? Maybe a UUID?
GetHitsCommand <-- asks for some hits. Command contains the query ID, and number of
hits being asked for. (-1 = all hits?) This command returns with a list of commands + a
flag telling the caller whether there are any more hits left from the node.
This is just a basic idea. I'm sure you can distil it further and improve on it. :)
