Layered flow type processing framework system and processing method

Abstract

The hierarchical streaming processing framework system comprises a database, a data access layer, a business logic layer and a presentation layer which are of a hierarchical structure from bottom to top, the data access layer accesses and operates the database, the business logic layer is responsible for operating the data layer and performing logic processing on data businesses, and the presentation layer is responsible for presenting the data businesses. The presentation layer is responsible for content presentation; wherein the business logic layer is divided into a main service and a plurality of sub-services, the main service is an assembly line for showing the processing flow of the sub-services, and each sub-service is a site on the assembly line and is used for processing specific business. The invention provides a service layering and streaming processing framework and method, which can improve service performance, reduce time consumption and effectively manage thread-level shared data and distributed shared data.

Description

technical field [0001] The invention belongs to the field of service processing, and in particular relates to a layered stream processing framework system and a processing method. Background technique [0002] Nowadays, the daily transaction volume of the financial system generally reaches one million, and the service call volume is usually one million. Many services, such as credit granting, are usually processed asynchronously due to their complex and time-consuming business. They are accepted first, processed through asynchronous tasks, and then called back or waited for the result query. In the process of task processing, there may be timeout or abnormal situations such as network communication timeout, long service time, manual review, network jitter, etc. In this case, the task needs to be rerun, that is, it is rescheduled. [0003] However, when a task is scheduled repeatedly, the following problems may occur: [0004] 1) The asynchronous task code is complex and ti...

AI Technical Summary

Problems solved by technology

When a certain piece of code that does not need to be executed is repeatedly executed, the following problems may be caused: business time-consuming lengthening; performance loss such as network communication and DB; if a system requests the same serial number again, it should support idempotence, but If the setting fails, the entire link fails

If the setting is too small, the task may fail when it is re-run; if the setting is too large, it will take up resources, and it is difficult to know how long the business will take. , it becomes permanent garbage, which is also inappropriate
