Problems solved by technology

During the application of the LRU algorithm, the threshold is usually set based on experience. If the number of data accesses is higher than the threshold, it will be stored in the memory. When the number of accesses of a large amount of data is less than the threshold, there will be less data cached in the memory. situation, resulting in low memory utilization

Abstract

The invention provides a memory data processing method and device which can be used in the financial field or other technical fields. The method comprises the following steps: collecting a storage reference value of a hot data area in a set period; wherein the hot data area is a preset area in a memory; if it is judged that the storage reference value is smaller than the corresponding reference threshold value, reducing an access threshold value; if it is judged that the number of access times corresponding to an access identifier in a cold data area is larger than the access threshold value, data corresponding to the access identifier is migrated to the hot data area; wherein the cold data area is a preset area in the memory. The device is used for executing the method. According to the memory data processing method and device provided by the embodiment of the invention, the utilization rate of the hot data area is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for processing memory data. Background technique [0002] At present, in the actual business system, there are repeated data reading operations. In order to improve the efficiency of data reading, the data can be cached in the memory, and the data can be read directly from the memory next time. [0003] In the prior art, due to the limited memory space, the least frequently used elimination (Least Frequently Used, referred to as LFU) algorithm and the least recently used elimination (Least Recently Used, referred to as LRU) algorithm are often used to manage the data in the memory, so as to improve the performance of the memory. utilization rate. During the application of the LRU algorithm, the threshold is usually set based on experience. If the number of data accesses is higher than the threshold, it will be stored in the memory. When the number of access...
