"Currently, CQL requests are processed on the same CPU core where the
connection lives in. This series adds infrastructure for migrating CQL
processing to other cores and implements a round-robin load balancing
algorithm that can be enabled with the "--load-balance=round-robin"
command line option. Load balancing is not enabled by default because we
need to first run performance tests to determine if the simple
round-robin algorithm is sufficient, or wheter we need to implement more
sophisticated dynamic load balancing."
