Abstract: Embodiments of the present disclosure provide a method and apparatus for determining a network model pruning strategy, a device and a storage medium. The method may include: generating a BN threshold search space using configuration information of the BN threshold search space for a network model for a target hardware; generating a pruning strategy code generator using the BN threshold search space; randomly generating a BN threshold code using the pruning strategy code generator; decoding the BN threshold code to obtain a candidate BN threshold; and determining a target pruning strategy of the network model for the target hardware, based on a pruning accuracy loss of the network model corresponding to the candidate BN threshold.

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.

Abstract: A query processing method is provided. 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 coodinator 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, generats a final query result, and feeds back the final query result to a user.
