Abstract

The invention relates to the field of financial science and technology, and discloses a data sampling method and device, equipment and a storage medium, and the method comprises the steps: carrying out the statistics of the total number of data entries of a plurality of to-be-calculated nodes, and obtaining a sampling ratio according to the preset number of to-be-extracted data entries and the total number of data entries; obtaining the total number of remaining unallocated data entries of an original data block in each node to be calculated, and obtaining the number of remaining data entriesto be sampled of each node to be calculated according to the total number of remaining unallocated data entries and the sampling ratio; and extracting a target data record from the original data blockaccording to the number of the remaining data entries to be sampled, and storing the target data record in a sampling result database. According to the invention, the technical problem of inaccuratesampling results of a specified number of traditional distributed data is solved.

Description

technical field [0001] The present invention relates to the technical field of financial technology, in particular to a data sampling method, device, equipment and storage medium. Background technique [0002] With the development of computer technology, more and more technologies (big data, distributed, blockchain, artificial intelligence, etc.) The industry's security and real-time requirements also put forward higher requirements for technology. [0003] The existing financial big data analysis and mining needs to analyze and process from a huge amount of data, and the difference between the data will lead to unbalanced data distribution. The sampling results of the traditional random sampling method are likely to have a large difference from the specified value, making The accuracy is low, which will cause inaccurate extraction results when extracting a specified amount of random data, thereby reducing the accuracy of the specified amount of data extraction and affectin...
