when the enterprise is registered and managed, the enterprise management micro-service of the service center processes the data and stores the data in a relational database, specifically a MySQL cluster.
Before sending the code, the enterprise sets the corresponding rule of the identification code, and the rule micro-service of the business center stores the rule into the Redis cache for quick calling when sending the code.
When the identification codes are sent, the identification data and the identification attribute data are processed by the identification micro-service of the service center and are stored in the MongoDB cluster. In particular, if a code-sending template is set, the template is also stored in the Redis cache.
And pushing the corresponding code sending data to the Kafka cluster while identifying the completion of code sending. The read is polled by the interface service of the resolution center, typically every 500 milliseconds. After acquiring the code sending data, the analysis center processes the code sending data according to a preset word segmentation rule and an analysis template, and stores the code sending data in an Elasticissearch cluster.
Particularly, the cache management micro-service of the analysis center records and analyzes the analysis log in real time, and refreshes the analysis hot words stored in the Redis cache in real time by combining historical data.
When the identification is analyzed, the analysis micro-service firstly queries a Redis cache, and if a result is obtained, the result is returned; and if no result exists, performing query in the Elasticissearch cluster.
When the identification relationship is retrieved, for example, when all the devices of one ship and the dependency relationship of the devices are retrieved, a specific index template is read from Redis, and the obtained result is retrieved in the Elasticissearch cluster according to the index.
