[0004] Although the above data caching method can ensure that the most recently accessed data is stored in the cache area, however, subject to the size of the cache area, more and more data will be covered. The data stored in the cache area is for the convenience of subsequent Repeated access to improve subsequent use is faster. If too much important data is overwritten, it is a waste of storage resources for the cache area, and at the same time reduces the query performance of the data

Embodiment Construction

[0061] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0062] The embodiment of the present invention provides a data caching method, such as figure 1 As shown, this method classifies the data to be cached according to the data characteristics corresponding to the data to be cached, and puts the classified data to be cached into the cache area in order of cache priority from high to low, so as to make full use of the storage area of ​​the cache area resources, and improve the query performance of d...

Abstract

The invention discloses a data caching method and device, which relate to the field of computer technology, and the main purpose is to make full use of the storage resources in the buffer area and improve the query performance of data. The main technical solution of the invention is: to obtain the data to be cached; according to the Classify the data to be cached according to the data characteristics corresponding to the data to be cached, and obtain the classified data to be cached; determine the cache priority corresponding to the classified data to be cached; according to the cache priority from high to low Put the sorted data to be cached into the cache area in the order. The present invention is mainly used for caching data.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data caching method and device. Background technique [0002] Caching technology is a common technology for data access in computer systems. When a computer system accesses data, it can store the most recently accessed data in the buffer, so that when the computer system needs to revisit the most recently accessed data, it will first read from the buffer. Query the recently accessed data in the cache area. If it is found, it will be executed directly. If the query cannot be found, it will be queried from the memory. Since the cache area runs much faster than the memory, the efficiency of data query is improved. [0003] In the process of data caching, the existing data caching method will continuously store the most recently accessed data in the cache area. However, as the application field of data continues to expand, the data in the buffer area will continue to increase, wh...
