摘要
Techniques for routing queries are provided. An ontological query is received by a query orchestrator. One or more query blocks, each specifying one or more operations and one or more quantifiers representing data flow between query blocks, are generated based on the ontological query. At least one data node is identified for each of the one or more query blocks based on the one or more quantifiers and the one or more operations. One or more of the identified data nodes are selected based on predefined cost criteria and one or more subqueries are transmitted to the selected one or more data nodes.
