Embodiment Construction

[0061] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

[0062] It should be noted that the "multiple or several" mentioned herein refers to two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

Abstract

The invention relates to an online transaction message deduplication method and device, a medium, a product and equipment. And caching a message de-reconfiguration list in a key value pair database, and storing a hash value corresponding to a specified primary key value of the received online transaction message by using a first bit vector table in a first vector table filter. When an online transaction message is newly received, the message deduplication configuration list is obtained from the key value pair database, and a corresponding message deduplication index primary key is determined. And determining whether the first hash value corresponding to the primary key value is stored or not, and if the first hash value is determined to be stored, indicating not to process the new online transaction message so as to realize message de-duplication. Due to the fact that the key value pair database can provide the message deduplication configuration list with low delay and high response speed, and the vector table filter can achieve quick search of the bit vector table, the timeliness of message deduplication can be effectively guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a method, device, medium, product and equipment for deduplication of online transaction messages. Background technique [0002] This section is intended to provide a background or context for implementations of the disclosure that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the development of information systems, the way of message interaction between online trading systems is becoming more and more sourced. With the intervention of technologies such as blockchain and Kafka distributed message publishing, it provides great convenience for the establishment of online trading systems, but at the same time it also brings the problem of message duplication. For example, suppose there are two nodes in the blockchain, A and B, and an online transaction message is sent to node A in...
