Embodiment approach

[0058] Based on the above embodiment, this embodiment further explains and optimizes the technical solution. As a preferred implementation mode, the aforementioned pull-up method also includes:

[0059] If the request object of the target read request does not exist in the statistics collection, insert the request object of the target read request into the statistics collection, and delete the request object of the request with the longest interval between the target read request and the statistics collection.

[0060] In this embodiment, if the request object of the target read request does not exist in the statistics collection, at this time, in order to ensure that all the collections stored in the statistics collection are the collections of the request objects accessed by the client within a recent period of time. In this case, the request object of the target read request can be inserted into the statistics collection, and the request object of the request with the longes...

Abstract

The invention discloses a hot data pull-up method and device, equipment and a medium, wherein the method comprises the steps: obtaining a statistical set when a target read request sent by a client is received; if the request object of the target read request exists in the statistical set, adding one to the statistical number of the request object of the target read request in the statistical set to obtain a target statistical number; if the target statistical number is greater than or equal to a preset threshold value, determining that the request object of the target read request is hot data; when the request object of the target read request is hot data, if the target read request needs to be forwarded to the low-speed storage pool, reading target data from the low-speed storage pool, and reading target residual data from the high-speed cache pool; and pulling up the target data to the cache pool, merging the target data and the target residual data, and feeding back the merged data to the client. Through the method, the pressure of a transmission network and a low-speed storage pool can be reduced while the response delay of the high-speed cache pool to the client is reduced.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a hot data pull-up method, device, equipment and medium. Background technique [0002] In a distributed storage system, due to the limited storage cost, in order to ensure the maximum utilization of hardware storage resources, the stored data is generally stored in layers to ensure the security and reliability of the stored data in the distributed storage system. See figure 1 , figure 1 Schematic diagram for hierarchical storage. In a distributed storage system, hot data with high user access frequency is usually stored in a cache pool, and cold data with low user access frequency is stored in a low-speed storage pool. Obviously, based on this data storage mechanism, as much hot data as possible should be stored in the cache pool. However, due to the capacity limitation of the cache pool, it is necessary to send the data with low access frequency in the cache pool to the low-s...
