Abstract

The invention discloses a data reading method, which comprises the steps of determining target data information according to a reading instruction when the reading instruction is received; judging whether corresponding target data exists in a preset cache or not according to the target data information; if yes, reading the target data from the preset cache, and feeding back the target data to a memory; if not, reading the target data from a disk according to the target data information, storing the target data to the preset cache, and feeding back the target data to the memory. According to the data reading method, the reading efficiency of the data information in the distributed data storage system is effectively improved. The invention further discloses a data reading device and equipment and a computer readable storage medium, which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a data reading method, and also to a data reading device, device, and computer-readable storage medium. Background technique [0002] Today, the rapid development of computer technology and network technology has promoted the arrival of the era of big data. The traditional centralized data storage system can no longer meet the needs of large-scale data storage. In order to effectively realize the storage of big data, the distributed data storage system has made great progress development of. [0003] However, one problem of distributed storage compared to centralized storage is that the back-end data crosses the network, which leads to relatively serious delay problems in the data reading process. For example, in the field of artificial intelligence, when using AI algorithms to identify massive data, multiple readings and multiple rounds of training are required f...
