Query
The routing key is optional in that implementers are free to
return null
. The routing key is an hint used for token-aware routing (see
TokenAwarePolicy
), and
if provided should correspond to the binary value for the query
partition key. However, not providing a routing key never causes a query
to fail and if the load balancing policy used is not token aware, then
the routing key can be safely ignored.
