Distributed data processing system and method

Abstract

The embodiment of the invention provides a distributed data processing system and method. The system comprises a load balancing device, routing devices and grading devices, wherein the load balancing device receives transaction data sent by a terminal and forwards the transaction data to the routing device with the minimum linking number among the multiple routing devices; each routing device receives the transaction data and forwards the transaction data to one of the multiple grading devices according to the Hash algorithm; each grading device receives the transaction data and stores the transaction data to a local memory in a distributed mode; each grading device carries out transaction exposure evaluation on the received transaction data and forwards a transaction exposure evaluation result to the routing device which sends the transaction data to the grading device; the routing devices forward the transaction exposure evaluation results to the load balancing device; the load balancing device forwards the transaction exposure evaluation results to the terminal. By means of the scheme, the data storage efficiency can be improved, and low-time-delay transaction data storage is achieved; high-concurrency trading volume can be supported, and the volume of data needing to be migrated during system volume expansion can be reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a distributed data processing system and method. Background technique [0002] With the advancement of informatization construction, electronic banking services such as personal online banking, mobile banking, telephone banking, and SMS banking have entered the stage of history one after another, and have won the favor of bank users by virtue of their convenient, fast and 7×24 hours of uninterrupted service. Changed people's lifestyles and consumption patterns. But at the same time, electronic banking also faces security risks that cannot be ignored. Criminal gangs use high-tech means to conduct real-time fraud and quickly transfer or withdraw funds, making it difficult for traditional T+1 post-event monitoring methods to meet the timeliness requirements. Therefore, the monitoring link must be moved from the back to the front, that is, the electronic banking system will ...
