[0034] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0035] It should be noted that the collection, collection, updating, analysis, processing, use, transmission, storage and other aspects of user personal information involved in the technical solution disclosed in the present invention are in compliance with the provisions of relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. Necessary measures are taken for user personal information to prevent illegal access to user personal information data and maintain the security of user personal information, network security and national security.

[0036] In the introduction of the embodiments of the present invention, the professional terms and their definitions are as follows:

[0037] Flink: Apache Flink is an open source stream processing framework developed by the Apache Software Foundation. Its core is a distributed streaming data flow engine written in Java and Scala, i.e., the development framework in this invention.

[0038] redis: Remote Dictionary Service, an open source log-based, key-value database written in ANSI C, supporting the network, memory-based and persistent, and providing APIs in multiple languages;

[0039] Checkpoint: Checkpoint is the core function of Flink to implement fault tolerance. It can periodically generate snapshots based on the status of each Operator / task in the data stream according to the configuration, so as to store these status data regularly and persistently.

[0040] xml: refers to extensible markup language;

[0041] springboot: a Spring framework. The Spring framework is an open source J2EE application framework and a lightweight container for managing the life cycle of beans.

[0042] Bean: describes the Java software component model.

[0043] In order to solve the technical problems existing in the prior art, the present invention provides a method for developing a business system, which can achieve the following technical effects based on the configuration-based development of Flink:

[0044] 1. Configure data ETL (abbreviation of Extract-Transform-Load, which is used to describe the process of extracting, transforming, and loading data from the source to the destination) based on XML. The development process is abstracted into several parts: data source source, data processing process, data processing unit processUnit, process end unit builder actionBuilder, process end unit sink. Developers only need to understand the meaning of the corresponding XML configuration, and do not need to understand the complex principles of flink. They can focus on implementing business logic. The association between streams is uniformly replaced by databases such as redis, which reduces the state occupation and guarantees performance.

[0045] 2. Based on the XML configuration method, components can be reused in different applications, which can significantly reduce the development time. It is easy for newcomers to get started. With a simple understanding, they can develop high-performance Flink programs;

[0046] 3. Flink version upgrades are transparent to developers, and are uniformly upgraded and converted by the backend. During the update iteration, you only need to repackage and launch.

[0047] A business system development method of the present invention mainly constructs the association relationship of the processing logic of the data source, data processing unit, process end unit, etc. required to build the flink topology by configuring the bean component in XML, and obtains the specific bean component through the bean container management of springboot in the startup function, draws the entire flink network topology, and finally submits the network topology to complete the business system development.

[0048] Figure 1 FIG. 1 is a schematic diagram of the main steps of the method for developing a business system according to an embodiment of the present invention. Figure 1 As shown, the method for developing a business system according to an embodiment of the present invention mainly includes the following steps S101 to S105.

[0049] Step S101: In response to the business system development instruction, obtain the business system identifier, and obtain the development configuration file according to the business system identifier. In an embodiment of the present invention, in response to the business system development instruction, the execution of a pre-set startup function can be triggered, so that by executing the startup function, specific components are obtained through the bean container management of springboot, and the entire flink network topology is drawn. The startup function is used to draw the network topology in flink.

[0050] For each business system to be developed, a business system identifier is assigned to it, and a pre-configured development configuration file is associated with it, so as to facilitate business system development according to the development configuration file. In one embodiment of the present invention, the main processing components are shown in Table 1 below.

[0051] Table 1

[0052]

[0053]

[0054] In an embodiment of the present invention, the underlying code logic can be built, and the corresponding bean class can be output through the different bean component configurations in Table 1 above to generate the final business system development code.

[0055] In an embodiment of the present invention, the development configuration file shown is implemented based on the extensible markup language XML tag, and the default schemas such as XMLSchema-instance, beans, spring-beans-3.0 are used for XML construction. Among them, XmlSchema is a substitute for DTD (Document Type Definition, a set of grammatical rules about tags) based on XML. XML Schema can describe the structure of an XML document. XMLSchema-instance: XML schema instance name; Beans: XML schema instance name; Spring-beans-3.0: XML schema instance name. XML is a document format that configures complex development logic in XML to improve readability. When the Java application is started, it will automatically read and parse the specified XML, and then associate each XML through the startup function to form a complete flink topology construction, replacing the formal java code development. Developers can build the entire execution process like building blocks, improving development efficiency.

[0056] In one embodiment of the present invention, the configured XML tags are shown in Table 2 below, and the tag attribute information is shown in Table 3 below.

[0061] The main component beans involved in the present invention include data source components, data processing components and process end components. The specific configuration file content is not described in detail here. Based on the characteristics of XML, basically an XML file represents a data source, and all corresponding data source processing can be configured through XML tags.

[0062] Step S102: Obtain the included components from the development configuration file, wherein the components include no less than one data processing component, wherein a component identifier associated with the component is defined in each component, and the connection mode between operators is defined in the attributes of the data processing component. In an embodiment of the present invention, in order to describe the association relationship between components, a component identifier associated with the component may be defined in each component, so that the next component associated with the current component may be obtained based on the current component. Generally, a business system may involve multiple data sources, and accordingly multiple development configuration files may be obtained, and then the included components may be obtained from each development configuration file to be used to construct a network topology corresponding to the business system.

[0063] According to one embodiment of the present invention, before obtaining the included components from the development configuration file, it may also include: configuring the operating environment of the development framework of the business system according to the operating environment parameter configuration information in the development configuration file. In an embodiment of the present invention, the development configuration file can be obtained through the WebApplicationUtils tool class embedded in the application framework, and flinkxmlbean can be obtained from the development configuration file to configure the operating environment StreamExecutionEnvironment of the business system development framework flink. The development framework flink requires a series of parameters to start, such as checkpoint timeout, checkpoint interval, number of checkpoints running at the same time, etc. After reading these parameter configurations from the XML development configuration file, the flink operating environment is initialized to complete the configuration of the operating environment.

[0064] Step S103: Determine the association relationship between components according to the component identifiers associated with the components defined in the components, and determine the connection relationship between data processing components according to the connection mode between the operators. In an embodiment of the present invention, the components also include a data source component and a process end component. Starting from the data source component, the associated components are obtained in turn according to the component identifiers associated with the components defined in the components, so as to obtain the association relationship between the components.

[0065] According to one embodiment of the present invention, the data processing component includes no less than one operator. The operator describes how to process data, and each data processing component may include one or more operators, which work together to complete data processing. Determining the connection relationship between the data processing components according to the connection mode between the operators may specifically include: obtaining the previous data processing component of the current data processing component according to the association relationship between the components; determining the connection relationship between the current data processing component and the previous data processing component according to the connection relationship between the first operator of the current data processing component and the last operator of the previous data processing component, so as to obtain the connection relationship between the data processing components. In the case where a data processing component includes multiple operators, the connection relationship between the current data processing component and the previous data processing component may be determined according to the connection relationship between the first operator of the current data processing component and the last operator of the previous data processing component.

[0066] In an embodiment of the present invention, the business system development framework is flink, and the connection modes between flink operators include forward, rebalance, keyby, etc. For example, there are two development configuration files xml, named A and B, each of which is configured with some properties, such as parallelism, connection mode, etc. After being parsed by the application framework springboot, two java instances are formed, and the flink topology is drawn according to the properties configured in the java instance. Taking the parallelism setParallelism as an example, if the connection mode of rebalance is set, .rebalance is added at the end, indicating that the data will be scattered and rebalanced when it is sent downward; taking keyby as an example, it means that hashing will be performed when sending data, and the same hash value will be sent to the same operator downstream, which requires adding .keyby (KeySelector construction class (incoming hash field)) after the instance.

[0067] Step S104: Construct the network topology corresponding to the business system according to the association relationship between the components and the connection relationship between the data processing components. In an embodiment of the present invention, the components obtained include a data source component, a data processing component and a process end component, wherein the number of each component is not less than one. When constructing the network topology corresponding to the business system according to the association relationship between the components and the connection relationship between the data processing components, specifically, it can include: taking the data source component as the starting component and the process end component as the ending component, and constructing the network topology corresponding to the business system according to the association relationship between the components and the connection relationship between the data processing components. According to the association relationship between the components, the sequence between the components and the flow direction of the data between these components can be obtained; according to the connection relationship between the data processing components, the connection mode between the data processing components can be obtained.

[0068] In one embodiment of the present invention, each acquired data source component is traversed, and one or more data processing components associated with the data source component can be acquired according to the component identifier associated with each data source component defined therein. Since, in general, data acquired from the data source needs to be processed by ETL or other data processing, the component associated with the data source component should be a data processing component. After acquiring the data processing component, the data processing component or the process end component associated with the data processing component is acquired according to the component identifier associated with the data processing component defined therein. At the same time, the connection relationship between the data processing component and its previous data processing component is determined according to the connection mode between the operators defined in the attributes of the data processing component. If the data processing component does not have the previous data processing component, the connection relationship between the data processing components cannot be acquired. If the data processing component has the previous data processing component, the connection relationship between the data processing component and the previous data processing component is acquired according to the connection mode between the first operator of the data processing component and the last operator of the previous data processing component. If the component associated with the data processing component is a process end component, then the data source component is taken as the starting component and the process end component is taken as the ending component. According to the association relationship between components and the connection relationship between data processing components, the network topology corresponding to the business system can be constructed. If the component associated with the data processing component is a data processing component, then continue to obtain the associated components of the associated data processing component until the process end component is obtained, and then the network topology corresponding to the business system can be constructed.

[0069] Step S105: Generate business system code according to the network topology to develop the business system. According to the network topology generated in the above steps, the corresponding business system code can be generated to complete the business system development.

[0070] According to one embodiment of the present invention, the method for developing a business system further includes: saving the intermediate result data generated by the data processing component into a database to share the intermediate result data. In the development of flink, state processing is an important feature of flink. The state here refers to the intermediate result data generated during the data processing process.

[0071] In the original data stream, the association between streams may be applied to the state to process the intermediate result data, but the use of the state should be kept cautious enough. Improper use will cause many problems in the entire Flink cluster, which is a great test of the developer's ability. In order to circumvent this problem and not affect the performance of Flink, the technical solution of the embodiment of the present invention introduces the redis database as a global state replacement, and the intermediate data is stored in redis. Those skilled in the art should know that other databases are also possible, such as MySQL.

[0072] A processUnit component is a data processing unit. When performing specific business logic processing, if the result data processed by other processUnits is needed, it can be obtained from redis. If it does not exist in redis, the parameters related to the logic itself will be saved in redis. When other processUnits process the same business logic, they also obtain the data stored by the previous processUnit from redis. In this way, with the help of redis, as long as two processUnits process the same business logic, no matter which one comes first or later, it can be guaranteed that the business logic is processed at least once.

[0073] In the embodiment of the present invention, the association of tables is completed based on redis, and redis is a pure memory storage, which can also ensure that the performance is on par with the state of dataStream, while avoiding a series of problems caused by the abuse of state (such as back pressure, tilt, etc.). The global characteristics of redis are used to replace the state of flink, which reduces the difficulty of flink in maintaining the state and improves the effectiveness of checkpoint.

[0074] At this point, a complete set of XML-based configurations has transformed complex Flink network topology development into configurable, easy-to-use development, and has a very positive effect on standardized development and improving system performance. Moreover, standardized configuration can also reduce many problems caused by project handover. In addition, XML configurations can also be visualized, so that business system development can be completed by dragging and dropping on the interface, simplifying the development process.

[0075] Figure 2FIG. 1 is a schematic diagram of the process of constructing a network topology according to an embodiment of the present invention. Figure 2 As shown, in one embodiment of the present invention, the process of building a network topology is as follows: first, obtain a development configuration file; then, configure the operating environment of the development framework according to the operating environment parameter configuration information in the development configuration file; thereafter, obtain all data source components, data processing components, and process end components from the development configuration file; loop through the data source components to obtain associated data processing components and process end components, and establish associations between components, and at the same time, obtain the connection relationship between data processing components according to the connection method between operators defined in the properties of the data processing components; and build a network topology based on the associations between components and the connection relationships between data processing components.
