Partial Map-Reduce #491

Closed Gerold103 closed 1 month ago

Gerold103 commented 2 months ago

Finalization of #442 from the community. The feature introduces map-reduce on a part of the nodes, depending on the specified bucket IDs. They automatically get located and on the subset of replicasets the map-reduce gets executed.

Compared to the full map_callrw(), this partial one can be faster when covers not all the replicasets.
