Embodiment Construction
[0061] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0062] The consistent hashing algorithm was proposed by MIT in 1997 (see extended reading [1]). The design goal is to solve the hot spot problem in the Internet. The original intention is very similar to CARP. Consistent hashing corrects the problems caused by the simple hashing algorithm used by CARP, so that DHT can be truly applied in the P2P environment.
[0063] In the transaction distribution system, a consistent hash ring is also us...

The present invention provides a method and device for determining the number of virtual nodes in a transaction system. The method includes: obtaining configuration parameters of transaction network entry institutions, the configuration parameters including the total number of virtual nodes of transaction network entry institutions, the number of institution centers of transaction network entry institutions, and the number of institutions. The transaction flow ratio of the center and the number of transaction processing systems of each institution center; according to the total number of virtual nodes of transaction network institutions, the number of institution centers of transaction network institutions, the transaction flow ratio of each institution center, and the number of transaction processing systems of each institution center Determine the number of virtual nodes for each transaction processing system, where the virtual nodes are associated with a real node corresponding to a transaction processing system in the consistent hash ring. It is used to solve the problems in the prior art that the ring building time is too long when the process starts, and the distribution ring of the adjustment mechanism takes a long time when the system resource changes or the system is abnormal, which affects real-time transactions.
Description
technical field [0001] The invention relates to the financial field, in particular to a method and device for determining the number of virtual nodes in a transaction system. Background technique [0002] E-commerce is a system that uses Internet technology to conduct business transactions. With the continuous development of e-commerce, e-commerce has increasingly become a powerful weapon in traditional industries. Electronic transaction system is an e-commerce platform and the core technology of e-commerce. Electronic transaction system It mainly includes transaction centralized processing system, transaction trigger processing system, transaction information distribution system and transaction settlement system. When a transaction is sent through the traffic portal, the transaction distribution system will analyze the transaction, and then send it to a specific transaction processing system for processing. [0003] In an actual production environment, multiple sets of tra...
