High-availability bill system and bill generating and processing method

Abstract

The invention discloses a high-availability bill system and a bill generating and processing method. The method comprises the following steps that: the instant generation of a bill: before bills are generated on batch, calling an API (Application Program Interface) instant generation bill in a BillGenSDK (Software Development Kit), pushing a bill instant generation message to a message queue, andcaching the instant generation bill in a Redis database; the mass generation of bills: calling an API mass generation bills in the BillGenSDK, and storing in a Mqsql database; and for the instant generation bill cached in the Redis database, through a way of information consumption, persistently storing in the MySQL database. By use of the method, strong dependency for the bill generation module is reduced, and bill display availability is improved. Meanwhile, the caching and the persistence of the instant generation bill are realized, the bill can be prevented from being repeatedly generated,generation efficiency is improved, query response time is shortened, the normal display of the bill is guaranteed, the availability of the bill system is improved, and user experience is improved.

Description

technical field [0001] The invention relates to the field of financial transaction control, in particular to a highly available bill system and a method for generating and processing bills. Background technique [0002] At present, the main function of the billing system is the display of user bills, which is usually highly dependent on user transaction summary data. The existing solution is: the scheduled task module generates monthly bills and personal bills regularly on the user's bill day through scheduled tasks, and persists them To the mySQL database, the billing system can query the user and billing year and month. The implementation of this solution is relatively intuitive and simple, and the coupling between the bill generation system, the transaction system, and the billing system is low. [0003] However, with the rapid growth of the number of users, the generation time of bills will continue to increase, which will lead to the continuous extension of the time req...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing billing system has a high probability of abnormal bills and transactions, poor usability, and seriously affects the user experience.
