Description

Technical Field

[0001] This application relates to the field of database technology, and in particular to a Redis dynamic configuration method, device, and storage medium. Background Technology

[0002] In a multi-tenant SaaS environment, some tenants need to use independent Redis instances. To meet the high concurrency and isolation requirements of the service, the service typically needs to manage multiple Redis connections. However, traditional Redis connection management methods have many limitations. Traditional Redis connection management uses static configuration files to manage Redis node connections and connection pool parameters. For example, the configuration file contains the URL address of each Redis node and related connection parameters. If a new Redis node needs to be added or connection pool parameters need to be adjusted, the configuration file must be manually modified and the service restarted for the configuration to take effect. This makes adding or removing nodes highly limited, connection pool adjustments inflexible, and the maintainability of the mapping relationship between tenants and Redis nodes poor. Summary of the Invention

[0003] To address the issue of Redis configuration requiring a restart to take effect and its inflexibility, this application provides the following technical solution:

[0004] Firstly, a method for dynamic Redis configuration is provided, including:

[0005] Monitor updates to configuration parameters for any Redis node in Nacos, as well as updates to the user-Redis mapping relationship. Configuration parameters are used to adjust the performance of Redis, and the mapping relationship is used to configure the correspondence between users and Redis.

[0006] Based on the updates to configuration parameters and mapping relationships, determine the update information corresponding to the Redis node;

[0007] The update information is broadcast to any Redis node so that the configuration center can receive the update information;

[0008] The configuration center updates the settings of the corresponding Redis nodes based on the updated information.

[0009] Furthermore, before monitoring updates to configuration parameters for any Redis node in Nacos and updates to the user-Redis mapping, the following steps are also included:

[0010] Associate Nacos with the service items of the Redis node;

[0011] Configure the Nacos connection information and listening rules in the Redis node's configuration file;

[0012] Connect Nacos to the Redis node to obtain the Redis configuration file template, so that Nacos can collect and update the configuration parameters and mapping relationships according to the configuration file template.

[0013] Start Naco listener on the Redis node.

[0014] Furthermore, monitor updates to configuration parameters for any Redis node in Nacos, as well as updates to the user-Redis mapping relationship, including:

[0015] The callback function is triggered when configuration parameters and / or mapping relationships are updated;

[0016] The updated configuration parameters and / or updated mapping relationships are parsed through callback functions;

[0017] Extract the Redis nodes corresponding to the updated configuration parameters and / or updated mapping relationships.

[0018] Furthermore, after broadcasting the update information to any Redis node so that the configuration center can receive the update information, it also includes:

[0019] The configuration center parses the update information to obtain the updated configuration parameters and the updated mapping relationships.

[0020] Furthermore, the configuration center updates the settings of the corresponding Redis nodes based on the updated information, including:

[0021] Initialize the Redis configuration parameters with the updated configuration parameters to make the Redis configuration parameters take effect;

[0022] Replace the original mapping in Redis with the updated mapping to make the Redis mapping take effect.

[0023] Furthermore, the configuration parameters include at least one of the following: URL address, maximum number of connections, minimum number of connections, and operation time;

[0024] Initialize Redis configuration parameters with the updated configuration parameters to make the Redis configuration parameters take effect, including:

[0025] Update the URL of the Redis node;

[0026] Update the maximum and minimum number of connections for each Redis node;

[0027] Initialize the Redis node configuration with the updated URL address, updated maximum number of connections, and minimum number of connections to make the configuration parameters of the Redis node effective.

[0028] Furthermore, the configuration center performs Redis settings based on the updated configuration parameters and the updated mapping relationships, including:

[0029] Update the user corresponding to the Redis node in the connection pool corresponding to the Redis node, so as to update the user-Redis mapping relationship;

[0030] Based on the updated user-Redis mapping, new users are routed to this Redis node.

[0031] Secondly, a Redis dynamic configuration device is provided, including:

[0032] The monitoring module is used to monitor updates to the configuration parameters of any Redis node in Nacos and updates to the user-Redis mapping relationship. The configuration parameters are used to adjust the performance of Redis, and the mapping relationship is used to configure the correspondence between users and Redis.

[0033] The information generation module is used to determine the update information corresponding to the Redis node based on the updates to configuration parameters and mapping relationships.

[0034] The broadcast module is used to broadcast update information to any Redis node so that the configuration center can receive the update information;

[0035] The update module is used to update the settings of the corresponding Redis nodes in the configuration center based on the update information.

[0036] Thirdly, a computer program product is provided, including a computer program that, when executed by a processor, implements the Redis dynamic configuration method described in the first aspect.

[0048] To address the issue that Redis configurations require a restart to take effect and are inflexible, this application provides the following embodiments.

[0049] In some embodiments, such as Figure 1 As shown, a Redis dynamic configuration method includes:

[0050] S100: Monitors updates to configuration parameters of any Redis node in Nacos and updates to the mapping relationship between users and Redis. Configuration parameters are used to adjust the performance of Redis, and mapping relationships are used to configure the correspondence between users and Redis.

[0051] S200: Determine the update information corresponding to the Redis node based on the update of configuration parameters and the update of mapping relationships;

[0052] S300: Broadcasts update information to any Redis node so that the configuration center can receive the update information;

[0053] S400: The configuration center updates the settings of the corresponding Redis nodes based on the updated information.

[0054] Node configuration parameters are obtained from stress test results.

[0055] Schematically, for a Redis configured with 1 core and 2GB of memory, and a server configured with 4 cores and 8GB of memory, the single-machine performance of the server is shown in Table 1.

[0056] Table 1 Single-machine performance of server

[0057] 8 150 90 110 16 280 95 120 32 450 105 135 64 600 125 160 128 700 160 220

[0058] From Table 1, the configuration parameters corresponding to the optimal performance can be obtained.

[0059] For example: when the number of connections is 8 and 16: Redis is under low pressure, the response time remains close to the normal level, and QPS increases linearly with the rise of the number of connections; when the number of connections is 32 and 64: Redis begins to approach the bottleneck, and the response time rises significantly; when the number of connections is 128: Redis is obviously overloaded, although the number of connections is large, the growth of QPS slows down, and the response time and TP95 deteriorate significantly.

[0060] Preferably, before S100: monitoring the update of configuration parameters of any Redis node and the update of the mapping relationship between users and Redis in Nacos, the method further comprises:

[0061] S010: associating Nacos with the service item of the Redis node;

[0062] S020: setting the connection information and monitoring rules of Nacos in the configuration file of the Redis node;

[0063] S030: connecting Nacos with the Redis node, acquiring the configuration file template of Redis, so that Nacos can collect the updated configuration parameters and the updated mapping relationship corresponding to the configuration file template;

[0064] S040: starting Nacos monitoring on the Redis node.

[0065] In the server-side project, introduce the dependencies of Nacos service discovery and configuration management, and configure relevant parameters.

[0066] Schematically, the association is performed in the following manner:

[0067] spring:

[0068] cloud:

[0069] nacos:

[0070] discovery:

[0071] server-addr:<Nacos server address>

[0072] config:

[0073] server-addr:<Nacos server address>

[0074] file-extension: yaml,

[0075] A configuration file template related to Redis is set. The configuration file template contains basic information such as node URLs and connection pool parameters.

[0076] In addition, independent connection pool parameters are configured for each Redis node separately, and the connection pool parameters include: maximum number of connections, number of idle connections.

[0077] Illustratively, the configuration method for the connection pool parameters is as follows:

[0078] redis:

[0079] nodes:

[0080] -name:node1

[0081] url:redis: / / 192.168.1.10:6379

[0082] pool:

[0083] max-active:50

[0084] max-idle:10

[0085] min-idle:5

[0086] -name:node2

[0087] url:redis: / / 192.168.1.11:6379

[0088] pool:

[0089] max-active:100

[0090] max-idle:20

[0091] min-idle:10

[0092] tenant-mapping:

[0093] tenant1:node1

[0094] tenant2:node2

[0095] Specifically, S100: Monitors updates to configuration parameters of any Redis node in Nacos and updates to the user-Redis mapping relationship, including:

[0096] S110: Trigger a callback function when configuration parameters and / or mapping relationships are updated;

[0097] S120: Parse the updated configuration parameters and / or updated mapping relationships through callback functions;

[0098] S130: Extract the Redis node corresponding to the updated configuration parameters and / or the updated mapping relationship.

[0099] By listening, the server can obtain Nacos configuration change events and update the connection pool parameters independently for each Redis node.

[0100] To illustrate, the listening mechanism is implemented as follows:

[0101] @NacosConfigListener(dataId="redis-config",groupId="DEFAULT_GROUP",

[0102] timeout=3000)

[0103] public void onConfigChange(String configContent){

[0104] / / Parse configuration content

[0105] RedisConfig redisConfig=parseConfig(configContent);

[0106] / / Update the connection pool configuration for each Redis node

[0107] for(RedisNode node:redisConfig.getNodes()){

[0108] RedisConnectionPool pool =

[0109] redisConnectionManager.getPool(node.getName());

[0110] pool.setMaxActive(node.getPool().getMaxActive());

[0111] pool.setMaxIdle(node.getPool().getMaxIdle());

[0112] pool.setMinIdle(node.getPool().getMinIdle());

[0113] }

[0114] / / Update the mapping between tenants and Redis nodes

[0115] updateTenantMapping(redisConfig.getTenantMapping());

[0116] }

[0117] Specifically, S300: After broadcasting the update information to any Redis node so that the configuration center can receive the update information, it also includes:

[0118] S310: The configuration center parses the update information to obtain the updated configuration parameters and the updated mapping relationships.

[0119] Specifically, S400: The configuration center updates the settings of the corresponding Redis nodes based on the updated information, including:

[0120] S410: Initializes Redis configuration parameters with the updated configuration parameters, making the Redis configuration parameters effective;

[0121] S420: Replaces the original mapping in Redis with the updated mapping, making the Redis mapping effective.

[0122] Specifically, the configuration parameters include at least one of the following: URL address, maximum number of connections, minimum number of connections, and operation time;

[0123] S410: Initializes Redis configuration parameters with the updated configuration parameters, making the Redis configuration parameters effective, including:

[0124] S411: Update the URL address of the Redis node;

[0125] S412: Update the maximum and minimum number of connections for a Redis node;

[0126] S413: Initialize the Redis node configuration with the updated URL address, updated maximum number of connections, and minimum number of connections, and make the configuration parameters of the Redis node effective.

[0127] The connection pool parameters for each Redis node are managed through the Nacos configuration center. The server dynamically adjusts the corresponding connection pool configuration based on detected changes. For example, if the workload of a node increases, its `maxactive` parameter can be adjusted from 50 to 100 in Nacos, and the change will take effect immediately on the server. If a node needs to reduce resource consumption, its `max-idle` and `min-idle` parameters can be adjusted, and the server will update them synchronously.

[0128] Specifically, S400: The configuration center performs Redis settings based on the updated configuration parameters and the updated mapping relationships, and also includes:

[0129] S451: Update the user corresponding to the Redis node in the connection pool corresponding to the Redis node, so as to update the user-Redis mapping relationship;

[0130] S452: Based on the updated user-Redis mapping, route new users to this Redis node.

[0131] If you need to adjust the Redis node corresponding to a tenant, simply update the `tenantmapping` field in the Nacos configuration center. The server will then detect the update and modify the mapping relationship between the tenant and the Redis node in real time. For example:

[0132] tenant-mapping:

[0133] tenant1:node3# This sets the Redis node of tenant1 to node3.

[0134] In Nacos, modifications to connection pool parameters (such as maximum number of connections, idle time, etc.) are automatically applied by the server upon detecting the changes. The automatic application process is illustrated below:

[0135] private void updateConnectionPool(PoolConfig poolConfig){

[0136] redisConnectionPool.setMaxActive(poolConfig.getMaxActive());

[0137] redisConnectionPool.setMaxIdle(poolConfig.getMaxIdle());

[0138] redisConnectionPool.setMinIdle(poolConfig.getMinIdle());

[0139] }

[0140] It should be understood that, although Figure 1 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0141] In other embodiments, such as Figure 2 As shown, a Redis dynamic configuration device includes:

[0142] The monitoring module is used to monitor updates to the configuration parameters of any Redis node in Nacos and updates to the user-Redis mapping relationship. The configuration parameters are used to adjust the performance of Redis, and the mapping relationship is used to configure the correspondence between users and Redis.

[0143] The information generation module is used to determine the update information corresponding to the Redis node based on the updates to configuration parameters and mapping relationships.

[0144] The broadcast module is used to broadcast update information to any Redis node so that the configuration center can receive the update information;

[0145] The update module is used to update the settings of the corresponding Redis nodes in the configuration center based on the update information.

[0146] For specific limitations regarding the Redis dynamic configuration device described above, please refer to the limitations of the Redis dynamic configuration method above, which will not be repeated here. Each module in the aforementioned Redis dynamic configuration device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device in hardware form, or stored in the memory of a computer device in software form, so that the processor can call and execute the operations corresponding to each module.

[0147] In other embodiments, such as Figure 3As shown, a computer device includes a memory, a processor, and a Redis dynamic configuration program stored in the memory and executable on the processor.
