Data system and data reading method

Abstract

A data system and a data reading method are provided in the present disclosure. The data system includes a processor, a memory, and a storage device. The processor includes a file system in user space. The memory includes a memory buffer. The user file space system receives a reading request sent by an application end. The file system in user space reads prefetch data of a target file pre-stored in at least one buffer block of the memory buffer according to the reading request. In response to the file system in user space determining that a total reading amount of a last buffer block with stored data from the at least one buffer block being currently read exceeds a preset total amount, the file system in user space prefetches a next batch of prefetch data of the target file from the storage device and stores it in another buffer block. Therefore a data reading operation of high efficiency is achieved.
