Abstract

Embodiments of the present application provide a control method, a data processing method, a data access method, and a computing device. Among them, determine the target data nodes that support access to the external storage system; determine the target access quantity of each target data node according to the storage capacity of the external storage system; notify each target data node of the corresponding target access quantity; wherein, each Each data node is used to control the access to the external storage system according to the corresponding target access quantity; according to the consumption of the access quantity of each target data node, re-determine the target access quantity of each target data node, and according to the determination result , to notify each target data node to update its corresponding target access quantity. The technical solution provided by the embodiment of the present application alleviates the access pressure of the external storage system.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data processing, and in particular, to a control method, a data processing method, a data access method, and a computing device. Background technique [0002] Distributed File System (DFS) uses multiple computers to cooperate to solve computing and storage problems that cannot be solved by a single computer. The distributed file system is mainly used for data storage, and data resources are stored in the form of files on the storage device of the physical machine. Among them, the distributed file system is mainly composed of a central node and various data nodes connected to the central node. A file is usually divided into one or more data blocks and distributed among different data nodes according to a certain strategy. The data nodes are mainly responsible for storing Data, the central node is responsible for the overall management of the data nodes and the client's access t...
