Memory computing service framework and implementation system

Abstract

The invention discloses a memory computing service framework and an implementation system. The service framework takes Nats as a message bus for communication between services; the service triggers business logic processing by subscribing a specified topic, and after the processing is completed, the memory state of the service framework is published to the specified topic in a message form; the service framework uses Hazelcast to cache a service state, and provides a unified persistence and query service to perform memory state persistence and query; query and subscription conditions are uniformly expressed by using SQL, and a Q & S subscription mode is creatively introduced to ensure that messages are not lost or duplicated in consumption. Through a predefined storage model and a unified storage query service, data storage and query are decoupled from business logic, read-write separation is realized, the problems of usability and reliability of data interaction are solved by introducing SQL, Q & S and other technologies, and the memory computing service framework is mainly applied to scenes such as transaction, risk control, shipping space, real-time monitoring, real-time index calculation and the like. The memory computing service framework can be popularized as a memory computing service standard framework.

Description

technical field [0001] The invention belongs to the field of memory computing, and relates to a memory computing service framework and an implementation system. Background technique [0002] Against the background of the tide of digitalization, with the growth of data production speed and data volume, as well as the improvement of real-time data processing requirements, the traditional data processing mode of "first landing, then processing" can no longer be accepted. Data must be generated with extreme Perform analysis and processing in a short period of time, and then output the results as the input of other systems. The database is no longer at the center of real-time data processing, but retreats behind the scenes as a carrier for analysis and operation after the data lands. However, for systems that require real-time performance, it is difficult to see the shadow of the database on the critical path, and most of them are based on the architecture of memory computing, bu...

Problems solved by technology

[0012] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides an in-memory computing service framework, which not only solves the problem that interface definitions, calling methods, and storage models cannot form a unified standard, but also solves the problem that data in various business systems cannot be separated from reading and writing.
