Claim 4:
5. The computer implemented method of claim 1 further comprising:
receiving, by the group of processor units, a query at an intermediate node in the intermediate nodes,
comparing, by the group of processor units, the query to the group of retained data sketches at the intermediate node;
sending, by the group of processor units, the query to a set of child nodes in the group of child nodes based on a match of the query to a set of retained data sketches for the set of child nodes, wherein a child node in the group of child nodes is skipped when a retained data sketch received from the child node does not have a match to an associated retained data sketch at the intermediate node;
aggregating, by the group of processor units, a group of results received in response to the query to form an aggregated result; and
returning, by the group of processor units, the aggregated result to a requestor.
