Abstract

The invention provides a data association method and system. The method comprises the following steps: obtaining a first key value pair from a first message queue; and based on the first key of the first key value pair, querying whether a second key value pair of a second message queue with the key equal to the first key exists in a preset key value pair memory, and if yes, combining the first keyvalue pair and the second key value pair, and outputting the combined first key value pair and second key value pair, and if not, storing the first key value pair in a key value pair memory. In the scheme, a first key value pair is obtained from a first message queue needing to be subjected to data association, and whether a second key value pair with the key equal to the first key exists or notis inquired from a key value pair memory. And if yes, the first key value pair and the second key value pair are combined and output. And if not, the first key value pair is stored into a key value pair memory for querying a message queue needing to be associated with the first message queue. Real-time association among a plurality of message queues is realized, the association accuracy is high, and the association cost is low.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data association method and system. Background technique [0002] With the rapid development of the field of big data, more and more enterprises are applying technologies related to big data to their own business. Among them, the more common technical products related to big data are data warehouses. [0003] Before applying the data warehouse to implement functions such as data storage and data analysis, the data needs to be extracted, transformed and loaded (Extract, Transform and Load, ETL). In the process of ETL, it is usually necessary to merge multiple data sources into one data source. At present, the more common data source merging method is to realize the merging of data sources based on the key-value pairs (key:value) of the compared data sources. The specific implementation method is: for example, for the first data source and the second data source with mu...
