[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The solution provided in this application is applied to a business application cluster, which includes a cache cluster, a distributed configuration center, and at least one cache synchronization SDK. Figure 1 shown.

[0045] The cache cluster SDK is used to provide local caching capabilities for hot data for various business applications, interact with the cache cluster server, and read the key value of invalid data from the distributed configuration center for data synchronization. The cache cluster SDK includes the SDK interface, hotspot module, and communication module. The main function of the SDK interface is to obtain key values ​​and key value invalidation. The main function of the hotspot module is hotspot maintenance and local cache maintenance. The main function of the communication module is key value access reporting, key value invalidation reporting, hotspot discovery monitoring, and hotspot invalidation monitoring.

[0046] During the startup and operation of the cache cluster SDK, it will read necessary configuration information from the distributed configuration center, such as the key initialization list, startup configuration, cache cluster address information, etc.

[0047] The cache cluster provides data reading and writing services for various business applications, receives cache access data reported by the cache cluster SDK, performs hotspot detection, and pushes the key of the hotspot data to various business applications through the distributed configuration center. The main functions of the cache cluster include hotspot detection, hotspot push, hotspot data collection, parameter encapsulation, and parameter push.

[0048] During the startup and operation of the cache cluster, the required configuration information will be read from the distributed configuration center, such as business application information, hotspot threshold configuration information, blacklist and whitelist information, etc.

[0049] The distributed configuration center provides the overall "cluster push" and "unified configuration" capabilities and is a basic component of the system.

[0050] The solution proposed in this application is to use the cache cluster SDK locally for hot data with high usage frequency, so that business applications can directly read and write, thereby improving data access speed; for non-hot data with low usage frequency, the cache cluster module at the remote end of the application is stored, and data is read and written with the data source, providing cache data hot spot detection and other capabilities. Cluster push and unified configuration are performed between the cache cluster SDK module and the cache cluster module through the distributed configuration center.

[0051] Figure 2 This is a flowchart of a local cache refresh method according to an embodiment of the present application.

[0052] like Figure 2 As shown, the local cache refresh method provided in this embodiment is applied to the above business application cluster to refresh the data in the local cache to avoid wasting system resources. The refresh method specifically includes the following steps:

[0053] S1. Respond to the business application's access request to the key value, enable the cache synchronization SDK to return the data corresponding to the key value to the business application based on the access request, and upload the business application's access event to the key value to the cache cluster.

[0054] That is, when a business application sends an access request for a key value, based on the request, the cache synchronization SDK returns the data corresponding to the key value to the business application that issued the request. The data is local cache data or remote data. The specific process includes the following:

[0055] When a key value sent by a business application is received, a search is performed from the existing hot key list based on the key value.

[0056] If the corresponding hot key value can be found, it will be searched from the local cache based on the key value and the found data will be given to the business application;

[0057] If the corresponding hot key value cannot be found, the remote cache cluster is accessed based on the key value, and the accessed data is returned to the business application.

[0058] In addition, the following is also included:

[0059] When a business application writes, deletes, or invalidates data in the local cache, invalidation processing is performed on the specific key value corresponding to the data being written, deleted, or invalidated. The process of implementing the processing is as follows:

[0060] The local cache data corresponding to the specific key value is deleted; and the key value invalidation event of the specific key value is pushed to the cache cluster; based on the key value invalidation event, the cache cluster pushes the specific key value to all other cache synchronization SDKs, so that other cache synchronization SDKs clear the local cache data corresponding to the specific key value, so as to achieve the final consistency of the cluster data.

[0061] S2. Receive access events uploaded by the cache synchronization SDK, analyze and calculate access data of different business applications based on a series of access events, and obtain a hotspot key list. The hotspot key list must include at least one hotspot key value.

[0062] Specifically, statistical analysis is performed on the access data to determine whether it is a hot key value based on the probability and quantity of the key value. The so-called hot key value refers to a key value that is repeatedly accessed by business applications, indicating that the corresponding data is repeatedly called by business applications. After statistical analysis, the key value corresponding to the repeatedly called local cache data is determined as the hot key value, and all hot key values ​​are summarized into a list, namely the hot key list. Obviously, the hot key list includes at least one hot key value.

[0063] S3. Broadcast the hotspot key list to all cache synchronization SDKs so that the cache synchronization SDKs can update their existing hotspot key lists.

[0064] In this way, all other cache synchronization SDKs can locally cache the data corresponding to the hot key list, that is, transfer the data in the library into the local cache, so that the system can obtain the corresponding data with extremely high efficiency when accessing it.

[0065] It can be seen from the above technical scheme that this embodiment provides a local cache refresh method, which is applied to a business application cluster, and the business application cluster includes at least one cache synchronization SDK, a cache cluster and a distributed configuration center for coordinating and controlling the cache synchronization SDK and the cache cluster. The local cache refresh method specifically responds to the business application's access request to the key value, so that the cache synchronization SDK returns the data corresponding to the key value to the business application based on the access request, and uploads the business application's access event to the key value to the cache cluster, and the data is local cache data or remote data; receives the access event uploaded by the cache synchronization SDK, analyzes and calculates the access data of different business applications based on a series of access events, and obtains a hot key list, and the hot key list includes at least one hot key value; sends the hot key list to all cache synchronization SDKs by broadcasting, so that the cache synchronization SDK updates its existing hot key list for update. In this scheme, the real-time, reliability and consistency of the cached data are guaranteed by refreshing the local cache, so that the business application system can run and respond at high speed.

[0070] Figure 3 A block diagram of a local cache refresh device according to an embodiment of the present application.

[0071] like Figure 3 As shown, the local cache refresh device provided in this embodiment is applied to the above business application cluster to refresh the data in the local cache to avoid waste of system resources. The refresh device specifically includes an access control module 10, a data processing module 20 and a list sending module 30.

[0072] The access control module is used to respond to business application access requests to key values, enable the cache synchronization SDK to return data corresponding to the key value to the business application based on the access request, and upload the business application's access event to the key value to the cache cluster.

[0073] That is, when a business application sends an access request for a key value, based on the request, the cache synchronization SDK returns the data corresponding to the key value to the business application that issued the request. The data is local cache data or remote data. Figure 4 As shown, the module specifically includes a key value search unit 11, a first search unit 12 and a second search unit 13.

[0074] The key value search unit is used to search from an existing hotspot key list based on the key value when receiving the key value sent by the business application.

[0075] The first search unit is used for searching from the local cache based on the key value if the key value search unit can find the corresponding hot key value, and providing the found data to the business application;

[0076] The second search unit is used to access the remote cache cluster based on the key value if the key value search unit cannot find the corresponding hot key value, and return the accessed data to the business application.

[0077] In addition, the access control module also includes an invalidation processing unit 14 .

[0078] The invalidation processing unit is used to perform invalidation processing on the specific key value corresponding to the data being written, deleted or invalidated when the business application writes, deletes or invalidates the data in the local cache. The process of implementing the processing is as follows:

[0079] The local cache data corresponding to the specific key value is deleted; and the key value invalidation event of the specific key value is pushed to the cache cluster; based on the key value invalidation event, the cache cluster pushes the specific key value to all other cache synchronization SDKs, so that other cache synchronization SDKs clear the local cache data corresponding to the specific key value, so as to achieve the final consistency of the cluster data.

[0080] The data processing module is used to receive access events uploaded by the cache synchronization SDK, analyze and calculate the access data of different business applications based on a series of access events, and obtain a hot key list. The hot key list must include at least one hot key value.

[0081] Specifically, statistical analysis is performed on the access data to determine whether it is a hot key value based on the probability and quantity of the key value. The so-called hot key value refers to a key value that is repeatedly accessed by business applications, indicating that the corresponding data is repeatedly called by business applications. After statistical analysis, the key value corresponding to the repeatedly called local cache data is determined as the hot key value, and all hot key values ​​are summarized into a list, namely the hot key list. Obviously, the hot key list includes at least one hot key value.

[0082] The list sending module is used to broadcast the hot key list to all cache synchronization SDKs, so that the cache synchronization SDK can update its existing hot key list.

[0083] In this way, all other cache synchronization SDKs can locally cache the data corresponding to the hot key list, that is, transfer the data in the library into the local cache, so that the system can obtain the corresponding data with extremely high efficiency when accessing it.

[0084] The local cache refresh device is based on Figure 5 The specific details in implement the refresh processing of local cache data.

[0085] It can be seen from the above technical scheme that this embodiment provides a local cache refresh device, which is applied to a business application cluster, and the business application cluster includes at least one cache synchronization SDK, a cache cluster and a distributed configuration center for coordinating and controlling the cache synchronization SDK and the cache cluster. The local cache refresh device specifically responds to the business application's access request to the key value, so that the cache synchronization SDK returns the data corresponding to the key value to the business application based on the access request, and uploads the business application's access event to the key value to the cache cluster, and the data is local cache data or remote data; receives the access event uploaded by the cache synchronization SDK, analyzes and calculates the access data of different business applications based on a series of access events, and obtains a hot key list, and the hot key list includes at least one hot key value; sends the hot key list to all cache synchronization SDKs by broadcasting, so that the cache synchronization SDK updates its existing hot key list for update.
