Embodiment 1

[0053] figure 1 It is a flow chart of the data caching method provided by Embodiment 1 of the present invention. The technical solution of this embodiment is applicable to the situation where the client or proxy sends cached data to the server. The method can be executed by the data caching device provided in the embodiment of the present invention. The device can be implemented in the form of software and / or hardware, and configured to be applied in a processor of the client or the agent.

[0054] The method specifically includes the following steps:

[0055] S101. Obtain a write request for cached data, and determine a hash slot corresponding to the cached data according to the write request.

[0056] The write request for cached data can be a write request for cached data input by the client received by the client, or a write request for the client to automatically read the cached data generated by the application, or a cached data sent to it by the client obtained by the a...

Embodiment 2

[0066] figure 2 It is a flow chart of the data caching method provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, the embodiment of the present invention adds the steps of the method for detecting the working status of the cache node. Such as figure 2 As shown, the method includes:

[0067] S104. Detect the working state of each cache node based on a preset detection sequence.

[0068] In order to ensure the validity and real-time performance of the data cache, it is usually necessary to make the cache nodes (servers) that provide the cache service in a normal working state. For this reason, the client or agent in this embodiment detects each cache node based on the preset detection order working status. It is understandable that the client or agent can also detect the working status of each cache node in real time, as long as the device performance of the client or agent can ensure the real-time performance of data cache, ...

Embodiment 3

[0079] image 3 is a schematic structural diagram of the data cache device provided in Embodiment 3 of the present invention. The device is used to execute the data caching method provided in any of the above embodiments, and the control device may be implemented by software or hardware, and configured for use on a client or an agent. Such as image 3 As shown, the device includes:

[0080] A write request acquisition module 11, configured to acquire a write request for cached data, and determine a hash slot corresponding to the cached data according to the write request;

[0081] Correspondence acquisition module 12, configured to acquire a correspondence between a hash slot and a cache node, and determine a cache node corresponding to the hash slot according to the correspondence, wherein the cache node is provided with a corresponding slave node ;

[0082] The sending module 13 is configured to send the cached data to the cache node corresponding to the hash slot, and t...

Abstract

The embodiment of the present invention discloses a data caching method, device, device, and storage medium, wherein the data caching method includes: obtaining a write request for cached data, and determining a hash slot corresponding to the cached data according to the write request; obtaining The corresponding relationship between the hash slot and the cache node, according to the corresponding relationship to determine the cache node corresponding to the hash slot, wherein the cache node is provided with a corresponding slave node; the cache data is sent to the The cache node corresponding to the hash slot, and the cache data is synchronized from the cache node to the slave node corresponding to the cache node. It solves the technical problem of complex data cache backup work in the prior art, reduces the complexity of data backup, ensures the security of cache data stored in cache nodes, and does not greatly increase the storage of cache data in other working nodes It is beneficial to ensure that other cache nodes are always in good working condition.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a data caching method, device, equipment, and storage medium. Background technique [0002] For most caching scenarios, only a key-value store that supports multiple reads and multiple writes is required. Existing mainstream server caching solutions include master-slave mode (Master-slave) and X-Cluster cluster. The Master-slave scheme appeared earlier and is suitable for scenarios with more reads and fewer writes, but not for scenarios with more reads and more writes. X-Cluster is the officially recommended cluster solution. It is decentralized and its performance scales linearly with the increase of nodes. Although it is suitable for scenarios with multiple reads and multiple writes, the deployment is relatively complicated. Moreover, these two data caching schemes are more complicated in terms of data backup, which makes the reliability of da...
