Abstract

The invention discloses a data processing method and device. The data processing method comprises the steps: cleaning target data from the data, wherein the target data comprise fields and values of data in the form of messages; performing de-duplication processing on the plurality of pieces of target data; and storing the multiple pieces of duplicate-removed target data in storage files of multiple tables in a landing mode at the same time, and guaranteeing that the number of the storage files is controllable and the size is balanced. The data processing method can solve the technical problems that in the prior art, only the data of a single table can be landed, and efficiency is low.

Description

technical field

[0001] The present invention relates to the field of data processing, in particular to a data processing method and device. Background technique

[0002] The anti-fraud technology in risk control needs to analyze multi-dimensional data. Through the collection and analysis of effective data, most of the massive data in related technologies are based on Hive storage and offline calculation. The traditional HiveSQL writing method and MapReduce MR framework. However, the current MapReduce landing algorithm is limited to the landing of a single table, and there is no general plan for batch landing of massive data, resulting in low data landing efficiency and less flexibility.

[0003] For the above problems, no effective solution has been proposed yet. Contents of the invention

[0004] Embodiments of the present invention provide a data processing method and device to at least solve the technical problem of low efficiency in the related art that only data in ...
