Data storage method and device, terminal equipment and storage medium

Abstract

The invention discloses a data storage method and device, terminal equipment and a storage medium. The method comprises the steps that according to detected to-be-stored data, writting the to-be-stored data into a data caching area in a memory; Synchronously writing the to-be-stored data as cache data into a disk cache file according to a memory mapping relation between the data cache area and thedisk cache file in the disk; And when it is determined that the data size of the disk cache file meets the capacity threshold condition, writing the cache data currently stored in the disk cache fileinto a disk storage file in a disk, and correspondingly deleting the cache data currently stored in the disk cache file. The embodiment of the invention can avoid the condition of data loss caused byusing a memory caching technology in the prior art, and can effectively reduce the frequency of input/output operation, reduce the system power consumption and improve the system performance while ensuring the integrity of the data.

Description

Technical field [0001] The embodiments of the present disclosure relate to log management technology, and in particular to a data storage method, device, terminal device, and storage medium. Background technique [0002] Generally, the mobile terminal writes data into the disk of the mobile terminal to store and manage the data. For example, the data may be log data generated during the running of an application installed on the mobile terminal. [0003] There are mainly two data storage methods in the prior art. The first method is to write data directly to a disk file. For example, as long as an application generates a log, it directly writes the log to a disk file. The second method is to create a fixed-size memory cache on the mobile terminal and write all data into the memory cache. When the memory cache capacity is full, the data in the memory cache is written to the disk file at one time, and the memory cache is cleared. For example, a fixed-size memory cache is created...

Problems solved by technology

This will inevitably lead to frequent I / O operations, not only wasting too much time, but also increasing the power consumption of the system

And because the data writing process uses the common I / O method, there will be duplicate physical memory pages in the physical memory of the mobile terminal, resulting in unnecessary memory consumption

In the second method, although I / O operations are effectively reduced, due to the defects of the memory cache technology itself, data loss may occur in some cases
