Method and device for responding to data processing request, equipment and storage medium

The embodiment of the invention belongs to the technical field of computers, provides a method and device for responding to a data processing request, equipment and a storage medium, and aims to improve the data processing efficiency and reduce the storage pressure on a model. The method comprises the following steps: determining a mapping relationship between each fragment in a plurality of models and a plurality of storage devices according to a version flow ratio among the plurality of models with different versions, wherein the version flow ratio represents the distribution ratio of the data streams to be processed by the models of different versions; in response to a received data processing request, determining a target version corresponding to the data processing request in the plurality of models; based on the mapping relationship, determining candidate storage devices mapped by a plurality of fragments in a target model belonging to the target version; and determining a target storage device from the
