  • Patent number: 11194807
    Abstract: A query processing method. A server node parses a query request and generates a corresponding logical plan; judges the logical plan belonging to an OLAP scale query service or an OLTP scale query service; in response to judging that the logical plan belongs to the OLAP scale query service, segmenting the logical plan into logical subplans. A coordinator node generates a first physical plan corresponding to the logical plan, and feeds back the first physical plan to the server node. The server node assigns each of the logical subplans to the corresponding worker node according to the first physical plan. The worker node processes the corresponding logical subplan to obtain a query subresult, and reports the processing subresult layer by layer. The server node summarizes the received processing subresult, generates a final query result, and feeds back the final query result to a user.
