Not unless you consider inserting and firing all rules in a
synchronous (single-threaded) application. The feasibility depends on
the frequency of arriving events, but if you receive one temperature
reading per minute from each city or town in India (less than 1,700),
you won't have any problems.

FWIW, the race condition does not occur with Drools versions 5.3.0 and
5.5.0; so it should not be in 5.6 either.
