Transaction record checking method and device, electronic equipment and storage medium

Abstract

The invention provides a transaction record checking method and device, electronic equipment and a storage medium, and belongs to the technical field of Internet. The method comprises the following steps: storing transaction records of two transaction parties in a first time period of a bill cycle into a memory in a hash table form, wherein the first time period comprises a first preset duration taking the end time of the previous bill period as the starting time in the bill period and a second preset duration taking the starting time of the next bill period as the end time in the bill period; generating updated hash tables and updated transaction records of the two transaction parties according to the read transaction records of the second time period and the hash table corresponding to the other transaction party; calculating hash values of the updated transaction records of the two transaction parties; and when the hash values corresponding to the two transaction parties are the same and the updated hash tables are the same, determining that the two transaction parties balance the bills in the bill period. According to the method and the device, the transaction records can be checked without fully storing the transaction records, so that the memory occupancy is reduced, and the checking time is shortened.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular to a transaction record verification method, device, electronic equipment and storage medium. Background technique [0002] During the transaction, for each transaction, the systems of both parties involved in the transaction will record the transaction records of the transaction. After the billing cycle is over, both parties to the transaction check each other's transaction records, and if the transaction records of both parties are consistent, the funds will be settled. [0003] In the related technology, when checking the transaction records of both parties A and B, the following method is mainly adopted: the transaction record files of both parties A and B are divided into buckets according to row hash, so that the transaction record files are split into n small files; Load the n small files of A into the computer memory in the form of a hash table; read the t...

Problems solved by technology

[0004] However, the above method needs to load all the transaction records of one party into the memory, which occupies a large memory space. Especially in the case of a large transaction record of one party, it may not be possible to load all the transaction records into the memory, resulting in the verification of the transaction records. process not working
