Subject Re: Data locality question

Welcome Jaguar,

Any operator can expose an affinity to one or more nodes in the cluster.
 The drill planner uses this information to best schedule each query
fragment.  This very flexible as it allows multiple operator's affinities
to be considered before making a scheduling decision.

thanks,
Jacques
