[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0041] The term "comprising" and its variations as used herein are open-ended inclusions, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the description below.
[0042] It should be noted that the concepts of "first" and "second" mentioned in this application are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.
[0043] It should be noted that the terms "a" and "a plurality of" used in this application are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".
[0044] Nowadays, in the process of software development using Kafka as middleware, a Kafka cluster environment is first set up for use throughout the software development process. During the software development process, multiple topics corresponding to different environments need to be created in Kafka, which helps to distinguish different environments and thus ensure environment isolation.
[0045] For example, consider four environments: development (dev), testing (test), pre-production (unprod), and production (prod). Kafka, as a message queue software, can create many topics that satisfy these four environments after it starts running, allowing different messages to be sent to different topics. For instance, backend logs are sent to the `back_log_topic`, and frontend logs are sent to the `front_log_topic`. Corresponding to these two types of messages, Kafka can create topic names corresponding to the four environments: `back_log_topic_dev`, `front_log_topic_dev`, `back_log_topic_test`, `front_log_topic_test`, `back_log_topic_unprod`, `front_log_topic_unprod`, `back_log_topic_prod`, and `front_log_topic_prod`. These topic names are distinguished by adding an environment identifier to the end of the message's corresponding topic name.
[0046] In known technologies, the above naming process is done manually. Depending on the environment and the corresponding operations for the message topic, the code may need to be modified again, or the same code may need to be copied and pasted multiple times. The workload of naming topics is very large, resulting in low efficiency. Furthermore, since the entire naming process is done manually, there is a high probability that the topic names will not be remembered due to the large number of topics to be named, which could lead to production accidents.
[0047] To address the aforementioned issues, this application proposes a method, apparatus, and computer-readable medium for processing message topics. By using runtime environment information and topic information of each message topic, the target topic information of the target message topic corresponding to the application and matching the current runtime environment is determined. This solves the problem of low topic naming efficiency and avoids production accidents caused by forgetting topic names due to the large number of names to be named manually.
[0048] See Figure 1 As shown, the implementation flow of the message topic processing method provided in this application includes:
[0049] Step 101: Obtain the runtime environment information corresponding to the current runtime environment of the application.
[0050] See also Figure 2 The diagram illustrates the architecture of the application runtime environment for the message topic processing method. The runtime environment can include one of the following: development environment, testing environment, pre-production environment, or production environment. The development environment is primarily used during the software development phase, while the testing environment is primarily used during the software testing phase, which may involve multiple rounds of testing, resulting in multiple testing environments. Figure 2 The test environment includes Test 1, Test 2, Test N, etc. The pre-production environment is a full regression environment before the production environment, and it is a running environment that is close to the production environment. The production environment is the environment in which actual business operations are carried out.
[0051] Specifically, what is obtained here is the runtime environment identifier corresponding to the current running environment of the application. The runtime environment identifier is used to represent the environment in which the application is running. For example, the environment identifier of the development environment can be dev, the environment identifier of the test environment can be test, the environment identifier of the pre-production environment can be unprod, and the environment identifier of the production environment can be prod. In this way, the corresponding Topic names in different runtime environments can be easily distinguished.
[0052] Step 102: Determine the topic information of each message topic currently corresponding to the application.
[0053] Next, the application obtains the current theme configuration information from the configuration center or configuration file. The theme configuration information includes the theme identifiers of each configured message theme, such as the first theme identifier of the first message theme that the application needs to use or the second theme identifier of the second message theme that needs to be deleted.
[0054] For example, the first message topic that the application needs to use is the name of the topic that the application needs to use. If there are multiple topics, they are separated by commas: `kafka.topics.using = topic_a, topic_b, topic_c`. The second message topic that the application needs to delete is the name of a topic that the application has used in the past but no longer needs: `kafka.topics.delete = topic_d, topic_f`. Multiple topics are also separated by commas. These second message topics that need to be deleted are generally topics that were created incorrectly in Kafka, or topics that are only temporarily used and will not be used later. Deleting these second message topics helps to clean up unused topics in Kafka, making resource management easier and facilitating the use of remaining topics.
[0055] Step 103: Based on the runtime environment information and the topic information of each message topic, determine the target topic information of the target message topic that matches the current runtime environment for the application, so that the application can perform corresponding operations based on the target topic information in the current runtime environment.
[0056] Next, the runtime environment identifier corresponding to the application's current runtime environment is assembled with the topic information of each corresponding message topic to obtain the target topic information of the target message topic. This target topic information may include a first target topic identifier and a second target topic identifier. The application's current runtime environment identifier is assembled with the first topic identifier of the first message topic currently corresponding to the application to obtain the first target topic identifier of the first target message topic that the application needs to use in the current runtime environment. The application's current runtime environment identifier is assembled with the second topic identifier of the second message topic currently corresponding to the application to obtain the second target topic identifier of the second target message topic that needs to be used in the current runtime environment.
[0057] Taking a Spring Boot application as an example, the configuration information is as follows:
[0058] The application will use topic names kafka.topics.using = topic_a, topic_b, topic_c. Topics that have been used in the past but are no longer needed and need to be deleted include kafka.topics.delete = topic_d. The environment identifier is spring.profile.active = dev. When configuring the code, developers only need to remember topic_a, topic_b, topic_c, topic_d. During the actual execution of the application, the reassembled topic_a_dev, topic_b_dev, topic_c_dev, and topic_d_dev will be used, based on the runtime environment and the corresponding target topic.
[0059] It should be noted that the application performs corresponding operations based on the target topic information in the current runtime environment in two phases: the application startup phase and the application runtime phase.
[0060] During the application startup phase, see Figure 3 The flowchart of the application startup phase of the message topic processing method provided in this application is shown in the figure:
[0061] Upon application startup, the system first retrieves the application's runtime environment information. It loads the topics the application will use and the topics to be deleted from the configuration file. Then, it obtains the topic names corresponding to the runtime environment. Here, the runtime environment identifier is assembled with the topic information used by the application or the topic information to be deleted to obtain the first target message topic to be used and the second target message topic to be deleted, as mentioned above. Next, it checks if the required first target message topic is missing in the preset middleware system (Kafka). If it is missing, it creates the required topic for the corresponding environment in Kafka and establishes a connection to that Kafka topic in memory. After successful connection establishment, it checks if the corresponding topic for the application's environment to be deleted exists in the preset middleware system (Kafka). If it does, it deletes the corresponding topic in Kafka and removes the connection to that Kafka topic in memory. Once the Kafka topic connection is successfully deleted, the application starts successfully. If the Kafka topic connection creation fails during topic creation or deletion, the application startup fails.
[0062] During the application runtime phase, see Figure 4 This application provides a flowchart illustrating the application runtime phase of the message topic processing method.
[0063] The application demonstrates two operations: producing messages and consuming messages. These operations can occur in various environments mentioned above, such as pre-production, production, and testing environments, and each environment has its corresponding Topic name, such as... Figure 2 As shown, Development Environment 1 corresponds to Development Environment 1 topics, Development Environment 2 corresponds to Development Environment 2 topics, Test Environment 1 corresponds to Test Environment 1 topics, Pre-production Environment corresponds to Pre-production Environment topics, and Production Environment corresponds to Production Environment topics. Based on the message topics in the middleware system that match the current running environment, the application produces messages to the middleware system and / or consumes messages from the middleware system.
[0064] When producing a message, the topic name A corresponding to the application's runtime environment is obtained, which is the production message topic corresponding to the first message produced by the application. The runtime environment identifier of the current runtime environment is assembled with the production message topic to obtain the target production message topic corresponding to the first message in the current runtime environment. Then, the message is sent to the target topic A, which means that the first message is delivered to the target production message topic of the middleware system, and the message delivery is completed.
[0065] When consuming a message, the application obtains the topic name A corresponding to its runtime environment, which is the consumption message topic corresponding to the second message to be consumed by the application. The runtime environment identifier of the current runtime environment is assembled with the consumption message topic to obtain the target consumption message topic of the second message in the current runtime environment. Then, the message is read from the target topic A, which is the second message is read from the target consumption message topic of the middleware system, and the message consumption is completed.
[0066] In summary, the message topic processing method disclosed in this application obtains the runtime environment information corresponding to the current runtime environment of the application, determines the topic information of each message topic corresponding to the application, and determines the target topic information of the target message topic matching the current runtime environment based on the runtime environment information and the topic information of each message topic, so that the application can perform corresponding operations based on the target topic information in the current runtime environment. This application determines the target topic information of the target message topic matching the current runtime environment of the application by using runtime environment information and the topic information of each message topic, solving the problem of low topic naming efficiency and avoiding production accidents caused by forgetting topic names due to the large number of names to be named manually.
