Run a parallel query partition-by-partition:.

This approach may somewhat complicate the client code, but can dramatically reduce the memory footprint used by the requestor.Р вЂќР’В«elow are two examples of PartitionedFilter usage:

This filter is intended to be used in advanced scenarios, when a caller wants to retrieve the results of parallel processing restricted to a subset of partitions. Filter which limits the scope of another filter to those entries that have keys that belong to the specified partition set.
