User data dynamic migration method and device

Abstract

The invention discloses a user data dynamic migration method and device, and relates to the technical field of distribution. The method comprises the steps of: collecting transaction behavior data of a target user, and storing the user data of the target user in a first data center; according to the transaction behavior data of the target user, determining whether a transaction place where the target user executes the business transaction is changed or not; and when the transaction place where the target user executes the business transaction changes, migrating user data of the target user from the first data center to a second data center, wherein the second data center is the data center closest to the transaction place after the change, and the first data center is the data center closest to the transaction place before the change. According to the invention, the user data is stored in the data center closest to the transaction site, so that the user data can be acquired from the closest data center, network transmission time delay can be greatly reduced, transaction time delay is reduced, and transaction performance is improved.

Description

technical field [0001] The invention relates to the field of distributed technology, in particular to a method and device for dynamic migration of user data. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The data centers of some large banking systems (especially multinational banking systems) are often established in multiple different cities, or even multiple different countries, and users may appear in any corner of the world, for example, a certain location in Hainan When a user accesses the data center in Beijing, it will increase the network delay much more than when a customer in Beijing accesses the data center in Beijing. When the transaction volume increases, if there is a large amount of transaction delay, it will occupy a large amount of system resources, making...

Problems solved by technology

[0005] An embodiment of the present invention provides a dynamic migration method for user data, which is used to solve the technical problem of long network transmission delay due to changes in user transaction locations in existing banking systems based on multi-active data centers. The method includes: Collect the transaction behavior data of the target user, wherein the user data of the target user is stored in the first data center; according to the transaction behavior data of the target user, determine whether the transaction location where the target user executes the business transaction changes; when the target user executes the business transaction When the transaction location changes, the user data of the target user is migrated from the first data center to the second data center, where the second data center is the data center closest to the transaction location after the change, and the first data center is the distance change The closest data center to the former trading location

[0006] The embodiment of the present invention also provides a user data dynamic migration device, which is used to solve the technical problem of long network transmission delay caused by the change of the user's transaction location in the existing banking system based on the multi-active data center. The device includes : The user transa
