Problems solved by technology

For example, some data shunting methods are based on the access characteristics of the logical block address to shunt the data, and the process of collecting the access characteristic information of the logical block address requires a lot of modifications to the driver layer code of the operating system kernel; some data shunting methods The method is to stream data based on the program context information. The process of collecting program context information requires a lot of modification of the code of the operating system kernel and some application codes; The code undergoes a lot of modification and requires manual participation

Abstract

The invention provides a data stream management method and device. The data stream management method comprises the steps of obtaining attribute information of a currently opened file; and distributingthe data stream to the file according to the current state information of the data stream and the attribute information of the file. Based on the characteristic that data is managed in a file mode, each file is automatically allocated to the corresponding data stream on the basis of the attribute information of the files, and the attribute information of the files can be directly obtained in thevirtual file system of the operating system kernel, that is, codes of the operating system kernel do not need to be modified, and codes of applications do not need to be modified.

Description

technical field [0001] The invention belongs to the technical field of data storage, and more specifically, relates to a data flow management method and device. Background technique [0002] In order to improve the performance of the memory, it is generally necessary to effectively distribute the written data. Taking the garbage collection (Garbage Collection, GC) performance of the memory as an example, if the written data can be effectively shunted and the data with a similar life cycle can be stored in the same block of the memory, the effective pages moved by the GC will be large Therefore, the write amplification factor (WAF) can be reduced, and the service life of the memory can be greatly increased and the performance of the memory can be improved. [0003] The existing method for shunting data usually requires more modifications to the operating system kernel and / or application codes. For example, some data shunting methods are based on the access characteristics o...
