Embodiment Construction

[0066]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0067] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly.

Abstract

The invention discloses an implementation method for time window accumulation. The method comprises the steps that statistical analysis is conducted to transaction data information through a time window slide accumulation algorithm at first; then, a position changing scope, and the size of a window body or step length are judged so as to select an applicable addition engine algorithm or a subtraction engine algorithm; and finally, statistical analysis and rapid query are conducted to a transaction data accumulation value and an acquisition value in a Redis Cluster database or an Hbase database. The method disclosed by the invention has the advantages that the problems that an SQL query algorithm is not flexible, a query throughput capacity is not high and query granularity is inaccurate under a multi-dimensional multi-scenario combinations can be solved; a rapid response can be made to acquisition of the time window accumulation value; and accuracy is increased.

Description

technical field [0001] The invention relates to the technical field of Internet information monitoring, in particular to a method for realizing time window accumulation. Background technique [0002] In the payment business, with the development of the business, risk control is more and more dependent on performing related logical operations through various cumulative values ​​such as the number of transactions occurred in multiple dimensions and scenarios within a specified time period, and through modeling, year-on-year , and the chain ratio method to determine the specific transaction risk. [0003] The cumulative value is calculated in the time window dimension, including the timing interval and the sliding scan interval; in the sliding window, the time window does not jump forward, but slides forward every unit time, and the sliding time length is set by yourself. , mainly involves three parameters: position exchange range, window size and step size, these three parame...
