Abstract

The invention discloses a data deduplication method and device. The method comprises the steps that service main keys of data to be processed are obtained, wherein the service main keys are fields representing data uniqueness according to service demands; the service main keys are converted into a unified preset format, and matching codes are generated; the generated matching codes are ranked according to a preset sequence so that verification codes can be generated; the verification codes after ranking are searched and compared with first verification codes arranged in front, and when the verification codes are identical with the first verification codes, distinguishing codes of the verification codes are marked as second distinguishing codes; the data marked as the second distinguishing codes in the verification codes are deleted. When multiple rows or multiple lines of data with the scale over a ten million level are processed, the data deduplication method is simple in configuration, convenient to use and high in operability, deduplication processing of multiple rows or multiple lines can be achieved at the same time, a great amount of processing time is saved, and efficiency of deuplication processing is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for deduplication of data. Background technique [0002] The current data deduplication method based on the data fusion system is to sort a column or a row of data to be deduplicated, and identify the duplicate data with a distinguishing code (1, 2), and delete the data marked as "2". Existing data deduplication methods are inefficient when deduplicating multiple rows or columns of data. Contents of the invention [0003] The object of the present invention is to provide a method and device for deduplication of data, which aims to solve the problem of low efficiency in deduplication of multiple rows or columns of data in the prior art. [0004] In order to solve the above technical problems, the present invention provides a method for deduplication of data, including: [0005] Obtaining the business primary key of the data to be processed, the busi...
