Data ahead-reading method, device, equipment and computer readable storage medium

Abstract

The invention discloses a data ahead-reading method, device, equipment and computer readable storage medium. The method comprises in advance storing data of a preset byte size of every file in a hardsick into preset storage equipment, wherein the data reading speed of the preset storage equipment is higher than that of the hard disk; receiving a data reading request sent by a client; determiningwhether data to be read exist in a cache space, if so, returning corresponding data to be read in the cache space to the client according to the data reading request, else, returning corresponding data to be read in the preset storage equipment to the client according to the data reading request. According to the data ahead-reading method, device, equipment and computer readable storage medium, data in the preset storage equipment is read, and the speed of reading the data of the preset storage equipment is higher than that of reading the data of the hard disk, so that the data ahead-reading method, device, equipment and computer readable storage medium can increase the speed of primary data reading and further improve the data reading efficiency.

Description

technical field [0001] The invention relates to the technical field of data reading, in particular to a data pre-reading method. The invention also relates to a data pre-reading device, equipment and computer-readable storage medium. Background technique [0002] The current era is the era of rapid development of the Internet. It has developed from PC to mobile Internet. The ubiquitous digital information has generated massive data and files, and these data and files are still growing. Faced with endless growth It is becoming more and more difficult to access, store and manage these data and files. In order to speed up the reading of these massive big data, the existing technology proposes a caching mechanism. In this caching mechanism, a read operation of the client is divided into two parts: actual read and pre-read. The actual read means that the location and data length of the read file are consistent with the actual read operation initiated by the user, and finally the...

Problems solved by technology

[0003] The read-ahead mechanism provided in the prior art does not store the data read by the read-ahead operation in the cache space because no read operation has been performed when it is read for the first time, so only Can read the corresponding data from the hard disk, because the reading speed of reading the data in the hard disk is slow, it will cause a delay when reading for the first time, and the reading speed is slow, resulting in the problem of low efficiency of reading data
