Embodiment 1

[0029] The embodiment of the present invention provides a data reading and writing method, figure 1 It is a schematic diagram of the implementation process of a data reading and writing method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0030] Step S101: Receive a data read instruction, where the data read instruction includes characteristic information of the data to be read.

[0031] Here, the data read instruction is used to read multimedia data or interactive information stored in the system or the data storage device. The data reading instruction includes characteristic information of the data to be read, and the characteristic information of the data to be read may include information such as operation information, data location information, and data length. Among them, the operation information may be the recorded specific operation process of the user in the system, the data location information ...

Embodiment 2

[0041] Based on the foregoing embodiment, the embodiment of the present invention further provides a data reading and writing method, figure 2 It is a schematic diagram of the implementation process of the data reading and writing method in the second embodiment of the present invention, such as figure 2 As shown, the method includes the following steps:

[0042] Step S201: Receive a data read instruction, where the data read instruction includes characteristic information of the data to be read.

[0043] Here, the data read instruction is used to read multimedia data or interactive information stored in the system or the data storage device.

[0044] Step S202: Search for a data index in the memory according to the characteristic information.

[0045] Here, the characteristic information of the data to be read includes the location of the data to be read, where the location of the data may be the actual storage address of the data. Correspondingly, the step S202 includes:

Abstract

The embodiment of the invention provides a data read-write method, a terminal and a computer readable storage medium, and the method comprises the steps: receiving a data reading instruction which comprises the feature information of to-be-read data; determining a hit data index in a memory according to the feature information; and reading data in a cache according to the hit data index, the cachebeing a solid state disk SSD.

Description

Technical field [0001] The present invention relates to the technical field of data storage, in particular to a data reading and writing method, a terminal and a computer-readable storage medium. Background technique [0002] In the fields of distributed storage systems and virtualization, due to the need to cope with pressure from different businesses at the same time, the input / output (I / O) speed of mechanical hard drives often becomes the bottleneck of the system. The usual way to solve this problem is to use high-performance memory with faster read and write speed as I / O cache between the business system and the disk, and try to swap hot data that is frequently read and written into the cache to improve the response speed of the system . [0003] However, in a large-scale system, the total amount of hot data can easily exceed the memory capacity, which results in frequent elimination and reloading of memory cache data to meet business needs, which greatly affects the cache eff...
