> Document all places in SQL engine where operations could work suboptimal in MDC deployment: fulfilling requests from remote DC when the same data is available in local one.
> Evaluate approaches to fix that: from filtering nodes by DC to incapsulating DC awareness feature into affinity function so that these optimizations could be reused even in single DC installation (e.g. sending requests only to the same cell/server rack etc).
