Dynamic routing method and apparatus for query engine in pre-computing system

Abstract

The present application discloses a dynamic routing method and apparatus for a query engine in a pre-computing system. The method includes: pre-obtaining cube data under a preset dimensional combination in a pre-computing system; determining a degree of aggregation of the cube data selected as expected under the preset dimensional combination after a query request is received; executing query processing on the query request in a first distributed query engine when the degree of aggregation of the cube data under the preset dimensional combination is high; and switching to a second distributed query engine to execute query processing on the query request when the degree of aggregation of the cube data under the preset dimensional combination is low. The present application solves the technical problem that the query response speed of the pre-computing query system is not ideal. Through the present application, the sub-second high-performance query response can be achieved. At the same time, as a result, higher concurrency can be supported so as to meet business needs, and the stability of the query system is simultaneously guaranteed.
