Data Prefetch Method and Apparatus, and Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 18344417 titled 'Data Prefetch Method and Apparatus, and Device
Simplified Explanation
The patent application describes a method for data prefetching.
- Data prefetching is a technique used to improve the performance of computer systems by fetching data in advance of it being actually needed.
- The method involves obtaining a first data access request, which is the initial request for data.
- Based on this first data access request and the data lifecycle, a data prefetch policy is determined.
- The data prefetch policy specifies how data should be stored in different storage mediums.
- The first data set, which includes at least one piece of data, is stored in a second storage medium.
- The data prefetch policy determines when and how much data from the first data set should be stored in a first storage medium.
- The data lifecycle indicates the duration for which data should be stored in the first storage medium.
- The second storage medium has a lower read/write access rate compared to the first storage medium.
Original Abstract Submitted
A data prefetch method is disclosed. Before data is prefetched, a first data access request is first obtained, and a data prefetch policy is determined based on the first data access request and a data lifecycle, so that a first data set stored in a second storage medium is stored into a first storage medium according to the data prefetch policy. The first data set includes at least one piece of data, the data prefetch policy includes at least a prefetch length, the data lifecycle indicates duration for storing data in the first storage medium, and a read/write access rate of the second storage medium is less than that of the first storage medium.
