Method and system for implementing concurrent execution of cache data access and loading

Abstract

The invention discloses a method for achieving the concurrent process of buffer data accessing and loading, which comprises using two data buffer areas to store data, wherein either of the data buffer areas is in an accessing state, and the other is in a wait state, using a data loading pointer and a data visiting pointer to point for the two data buffer areas, using the data loading pointer to point for the data buffer area in the wait state when loading for buffer data, and loading buffer data, and simultaneously using the data visit pointer to point the data buffer area in the accessing state if buffer data are needed to be accessed, and accessing buffer data. Data can be accessed when loading data according to the method without influencing the accuracy of accessing data, and the speed of accessing data can be improved.

Description

technical field

[0001] The present invention relates to data caching, in particular to a method and system for realizing concurrent caching data access and loading. Background technique

[0002] In Internet data access, the client will frequently search for and read some relevant content in the request service for querying, inserting and updating data on the access server, such as the search request service. Generally, these read The content data is stored on the disk, which affects the speed of accessing the data due to the slow speed of reading the disk.

[0003] The way to improve is to store the data that needs to be read frequently in the memory in advance before accessing, because the speed of computer access to memory is much higher than the speed of accessing disk, which will greatly increase the speed of accessing data. However, the prior art does not solve the problem of loading data in memory and accessing data at the same time, and data loading is a time-consumi...
