Problems solved by technology
[0003] Because the data read operation only reads the main OSD data, it will lead to unbalanced OSD data access; the unbalanced data access will cause too many operation requests on some OSDs, resulting in a backlog of I / O operations, while other OSDs are in an idle state , thus reducing the data read speed

The invention discloses a data reading method, a terminal, a server and a storage medium, and the method comprises the steps: responding to a reading request of target data, and transmitting an information query request to a plurality of servers where the target data is located; receiving the distance between each server and the local terminal and the average number of data read-write times in a preset time period sent by each server according to the information query request; determining a target server and sending a reading request of the target data to the target server based on the distance between each server and the local terminal and the average number of times of data reading and writing of each server in a preset time period; and receiving the target data sent by the target server. By adopting the technical scheme of the invention, the optimal target server for reading the target data can be screened out according to the distance between the server and the terminal and the current data read-write frequency of the server, and the target data is read through the target server, so that the reading speed of the target data is increased.
Description
Technical field [0001] This application relates to the field of Internet communication technology, and in particular to a data reading method, terminal, server and storage medium. Background technique [0002] In the distributed file system, the data read operation is mainly to read the main object storage device (OSD). At the client, multiple OSDs are calculated through the Crush algorithm, and the main OSD is found. The main OSD is generally the first of the three copies; then the data is read directly on the main OSD. [0003] Because the data read operation reads only the main OSD data, it will cause the imbalance of OSD data access; the imbalance of data access will cause too many operation requests on some OSDs, resulting in a backlog of I / O operations, while other OSDs are idle , Thereby reducing the data reading speed. [0004] Therefore, it is necessary to provide a data reading method, terminal, server and storage medium to increase the data reading speed. Summary of the...
