Embodiment Construction

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solution of the present application. To illustrate, rather than limit, the technical solutions of the present application, the embodiments of the present application and the technical features in the embodiments can be combined without conflict.

[0036] In the data storage system, there are two common types of data. Among them, hot data is the data unit that will be frequently processed by the central processing unit (CPU, Central Processing Unit) in the future; cold data is the data unit that will be processed frequently in the future. Data units that are not frequently processed by the CPU generally have a la...

Abstract

The invention discloses a data processing method and device. The method comprises the steps that data access equipment acquires at least one data unit processed by a central processing unit (CPU) of the data access equipment in a first period; the data access device determines a cold and hot data index value of each data unit in the at least one data unit; the data access equipment takes T data units with maximum cold and hot data index values in the at least one data unit as a first set; aiming at a first data unit in the at least one data unit; if the data access device determines that the first data unit is located in the first set in N continuous periods before the first period and is not stored in the CPU cache, the first data unit is stored in the CPU cache; wherein the first data unit is any one of the at least one data unit.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data processing method and device. Background technique [0002] In the data storage and retrieval system, there are two common types of data. Among them, hot data is the data unit that will be frequently processed by the central processing unit (CPU, Central Processing Unit) in the future; cold data is the data unit that will be processed frequently in the future. Data units that are not frequently processed by the CPU generally have a large amount of data, such as historical data. Putting hot data into the cache first will undoubtedly reduce the data swapping in and out of the cache, thereby improving the performance and efficiency of CPU processing. It is necessary to identify hot and cold data. [0003] Therefore, how to determine the hot and cold data and improve the accuracy of data processing is an urgent problem to be solved. Contents of the invention [0004] The emb...
