In this embodiment, referring to fig. 1, the data real-time stream processing method includes the following steps:
s1, developing a rule model;
s2, determining the incidence relation between the rule model and the corresponding threshold parameter;
s3, injecting the associated threshold parameters into the rule model;
s4, combining the rule models into an operation rule;
s5, acquiring service data, and matching the service data with the analyzed operation rule to generate an early warning message;
and S6, pushing the early warning message.
In the present embodiment, the data real-time stream processing method may be performed using the data real-time stream processing system as shown in fig. 2, i.e., the steps S1-S6 are performed using the data real-time stream processing system.
Referring to fig. 2, the data real-time stream processing system includes an application layer, a job management layer, a rule parsing layer, a calculation layer, early warning message middleware, and a data source. The application layer is responsible for data source management, rule model management, operation management, early warning pushing, early warning visualization and early warning tracing, and is in butt joint with the operation management layer, the rule analysis layer and early warning message middleware; the operation management layer is responsible for operation monitoring, operation log and operation submission and is in butt joint with the computing layer; the rule analysis layer is responsible for associating the rule model with the data source, injecting threshold parameters into the rule model, and combining the rule models to finally form operation; the computing layer is realized based on an open source real-time computing framework flink, is responsible for receiving the service data of the data source, matches the analyzed operation rule in real time, and generates an early warning message and writes the early warning message into an early warning message middleware when the service data is matched with the rule; the early warning message middleware is responsible for carrying out persistent cache on the early warning message written in the computing layer to avoid loss, pushing the early warning message to the application layer in real time, and carrying out visualization by the application layer or forwarding the early warning message to an external system; the data source refers to a service data storage location, and the embodiment supports multiple data sources, including a message middleware kafka, a distributed key value pair database hbase, a relational database pgsql, a relational database mysql, a relational database oracle, and a full-text search engine elastic search.
In this embodiment, step S1 may be executed by the data source, that is, the step of developing the rule model is executed; executing steps S2-S4 by the rule analysis layer, namely determining the incidence relation between the rule model and the corresponding threshold parameter, injecting the associated threshold parameter into the rule model, combining a plurality of rule models into an operation rule and the like; executing step S5 by the computing layer, that is, acquiring the service data, and matching the service data with the parsed operation rule, thereby generating an early warning message; step S6, i.e., the step of pushing the warning message, is performed by the middleware.
In this embodiment, the middleware executes step S6 to push the warning message to the application layer. The application layer receives the early warning message pushed by the middleware, can visualize the early warning message, or forwards the early warning message to the outside.
In this embodiment, the data source, the rule parsing layer, the computing layer, the middleware, the application layer, and the job management layer are isolated by setting computing resources, so that each job runs in a completely isolated computing environment, and mutual influence is avoided. The method has the advantages of isolating computing resources and running logs, and is convenient for subsequent positioning problems.
In this embodiment, step S2, namely, the step of determining the association relationship between the rule model and the corresponding threshold parameter, includes:
s201, selecting a data source of service data;
s202, associating an event date field in a data source, wherein the event date field is used as rule alarm time;
s203, compiling a judgment rule;
s204, exposing threshold parameters corresponding to the judgment rules;
s205, declaring a threshold parameter.
The principle of steps S201-S205 is shown in fig. 3. Firstly, selecting a data source of business data, associating an event date field in the data source for being used as rule alarm time subsequently, writing a judgment rule and exposing a corresponding threshold parameter, and finally declaring the rule threshold parameter for injecting an actual threshold parameter value during the generation of subsequent operation.
In this embodiment, step S3, namely the step of combining a plurality of rule models into a job rule, includes:
s301, pulling a plurality of rule models;
s302, associating the rule models in an OR mode, wherein the association result is an operation rule.
The principle of steps S301-S302 is as shown in fig. 4, first, a developed rule model is injected with specific parameter values according to its registered threshold parameters; and then judging whether other rule models need to be added according to business needs, if so, pulling other rule models and associating with the existing rule models, wherein the association mode comprises a sum and/or, and means that the two rule models are only established when both the two rule models meet the condition, or means that the two rule models are established as long as one of the two rule models meets the condition. And finally, configuring the operation, wherein the operation comprises the resource quota (such as CPU core number, memory number and the like) of the operation and an early warning pushing end, and the early warning pushing end is used for pushing early warning information to a corresponding external system when the subsequent operation is performed.
In this embodiment, step S5, namely, acquiring the service data, and matching the service data with the parsed operation rule, so as to generate the warning message, includes:
s501, generating a computing node set according to the computing environment configuration of the operation rule;
s502, performing data source registration and user-defined function registration;
s503, executing computing resource docking, and distributing the operation rule to the computing nodes in the computing node set for computing;
s504, acquiring service data from a data source;
s505, matching the service data with the operation rule in real time;
s506, if the business data and the operation rule accord with the matching rule, the business data is packaged into early warning information.
When the data real-time stream processing method is executed using the data real-time stream processing system, the principle of steps S501 to S506 is as shown in fig. 5. Referring to fig. 5, a job management layer generates a corresponding computing node set according to the computing environment configuration of a job, then calls a job submission module, and the job submission module performs data source registration, user-defined function registration, and final and actual computing resource docking and distribution of the job to the corresponding node for computing. The operation receives the data of the service data source, matches the data with the rule in real time, and encapsulates the data according with the matching rule into an early warning message which is sent to an early warning push end in real time.
In this embodiment, the principles of the data real-time stream processing method and the data real-time stream processing system are described with reference to specific examples. Referring to fig. 6, in the present embodiment, two regular models are selected, where a first model is a water immersion point early warning model, a parameter value of the first model is that a water level is greater than or equal to 10 centimeters, and a water immersion point is a xxx tunnel; the second model is a traffic jam model, the parameter value of the traffic jam model is that the jam index is greater than or equal to 3, and the jammed road section is a xxx tunnel. The combination relationship of the two models is yes. The whole operation shows that when rainfall high water level occurs in the xxx tunnel and road congestion is found, the information is pushed to an emergency department to process related problems.
In this embodiment, the real-time stream processing method and the real-time stream processing system can implement an atomic rule model, a custom rule model, a model combination, a model multiplexing, an operation alarm pushing, a real-time calculation, a state retention, a fault-tolerant processing, a concurrent calculation, and the like. The atomic rule model is an atomic model which provides various established service domain atomic models, such as waterlogging-prone point early warning in an emergency scene, safety helmet AI early warning in a building scene, atmospheric site early warning in an ecological scene and the like, and can be directly injected into a threshold value for use; the self-defined rule model is an atomic rule model which is already defined and also supports the user to define the rule model. Selecting a data source, configuring a judgment rule and exposing a threshold parameter, and flexibly compiling a service rule by simply combining and defining condition factors; the model combination refers to that if there are associable general attributes such as people, events, places, objects, organizations and the like in a plurality of different models, the models are combined with each other to form a new special model; the model multiplexing refers to that the created model supports parallel execution of a plurality of jobs with different parameters, and the jobs are completely isolated and do not influence each other; the operation alarm pushing refers to supporting an operation alarm subscription pushing function, judging alarms in real time and pushing the alarms to a subscription end in real time. One job supports a plurality of subscribers, and the same alarm data is issued to different subscribers at the same time.
The real-time stream processing method and the real-time stream processing system in the embodiment can realize the abstraction of the rules and combine the real-time stream processing and the rule engine. The abstraction of the rule means that the rule is divided into a rule model and a rule operation, wherein the rule model is used for declaring a threshold parameter, and the rule operation is used for injecting a specific threshold parameter and realizing the combination of a plurality of models. Based on the description, the rules and the parameters can be effectively decoupled, the rules can be multiplexed and recombined according to the service requirements, and the repeated work is reduced. In addition, the isolation of computing resources can effectively divide different operations, avoid mutual influence and effectively help the service staff to separate the service rules from the application program codes.
