Embodiment Construction

[0058] The cold and hot data separation method provided in the embodiment of this application can be applied to such as figure 1 computer equipment shown. The computer device includes a processor, memory and a network interface connected by a system bus. Wherein, the processor of the computer device is used to provide calculation and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, computer programs and databases. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The network interface of the computer device is used to communicate with an external terminal via a network connection. Optionally, the computer device may also include a display screen and an input device. Optionally, the computer device may be a server, a personal computer (PC for short), a ...

Abstract

The invention relates to a cold and hot data separation method and device, computer equipment and a storage medium. The method comprises the steps of adopting a file system to determine the cold and hot attributes of to-be-written data; if the to-be-written data is cold data, writing the to-be-written data into a first data block of a memory; if the to-be-written data is hot data, writing the to-be-written data into a second data block of the memory, wherein the first data block and the second data block are physically isolated. According to the method, the cold and hot attributes of the to-be-written data can be accurately determined by utilizing the file system, so that the cold and hot data separation accuracy is improved, physical isolation of the cold and hot data is realized, the influence of the hot data on the cold data during reading or writing operation is further avoided, and the writing amplification of the cold data is greatly reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for separating hot and cold data. Background technique [0002] With the continuous development of storage technology, NAND Flash memory has been more and more widely used in the industry due to its advantages such as large capacity and fast rewriting speed. Usually, a non-full data block block is reserved in the NAND Flash memory, and the data to be written by the system (including hot data and cold data) will be written into this block. Among them, the hot data is updated faster and the invalid pages increase more, so the invalid pages of the hot data need to be recycled frequently, while the cold data is not updated frequently, but because the hot and cold data are stored in the same data block, the cold data will still be invalid due to the hot data Page recycling is often read and written, which leads to lo...
