Embodiment Construction

[0066]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0067] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change 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 increasingly dependent on the cumulative value of the number and amount of transactions that occur within a specified period of time through multiple dimensions and scenarios to perform relevant logical operations, and through modeling, year-on-year , The chain 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 scanning interval; in the sliding window, the time window does not jump forward, but slides forward every time a unit of time passes, and the length of the sliding time is custom-set , mainly involves three parameters: position exchange range, window size and step size, these...
