Embodiment Construction

[0046] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0047] The inventors of the present application have discovered through research that a data storage device such as a hard disk can be used to store data, and when the data needs to be viewed or used, the data can be read from the storage device such as a hard disk. However, the speed of reading data from the hard disk is generally slow, and the data reading effici...

Abstract

The present application discloses a data reading method and device, including: obtaining a data reading request for requesting target data; according to the data reading request, using a hash list to determine whether the target data is in memory; if If the target data is in the internal memory, read the target data from the internal memory. It can be seen that, using the data reading method and device provided by the embodiments of the present application, it is possible to first determine whether the target data is in the internal memory, and if the target data is in the internal memory, the target data can be directly read from the internal memory without having to read the target data from the internal memory. The target data is read from a storage device such as a disk, and the time taken to read the target data from the memory is shorter than the time taken to read the target data from the storage device, thereby improving the efficiency of reading the target data.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a data reading method and device. Background technique [0002] With the development of information technology, massive amounts of data are generated. Currently, a data storage device such as a hard disk can be used to store data, and when the data needs to be viewed or used, the data is read from the storage device such as a magnetic disk. [0003] However, the speed of reading data from the disk is generally slow, and the data reading efficiency is low. [0004] Therefore, it is necessary to provide a solution that can improve the efficiency of data reading. Contents of the invention [0005] The technical problem to be solved in this application is how to improve the efficiency of data reading, and provide a data reading method and device. [0006] In the first aspect, the embodiment of the present application provides a data reading method, including: [0007] O...
