Problems solved by technology

However, when generating embedded IDs in a distributed system environment, if you do not rely on the central service, there will be situations where duplicate IDs will be generated. When assigning table IDs, you need to manually assign values, without deep integration, and at the same time lack necessary APIs, such as reverse Interpretation, translation time, etc., cannot meet business needs

Abstract

The invention discloses a globally unique distributed ID (Identity) generation method, which comprises the following steps of: pre-configuring an embedded publishing mode, and acquiring a local IP (Internet Protocol) when a service instance is started; an instance list file is generated in a local machine, and a machine serial number is returned after service instances are registered; performing bit operation on the IP and the machine serial number to obtain a globally unique machine bit; the method comprises the following steps: defining displacement digit information of each item and a maximum limit sequence of the digit when an ID is generated through idMeta, performing rightward digit operation on the generated ID, and performing AND operation on the generated ID and the maximum limit sequence of the digit to obtain a numerical value of the ID when the ID is generated; and performing leftward operation on the machine bit and the version number, the time type, the current time and the current machine serial number defined by the IdMeta to obtain a unique distributed ID. According to the method disclosed by the invention, the global uniqueness ID can be generated without relying on a central service during embedded use, the problem of ID repetition is solved, the storage space is saved, the performance is improved, and the requirement when the business growth speed is relatively high is met.

Description

technical field [0001] The content of the present invention relates to the technical field of data processing, in particular to a globally unique distributed ID generation method. Background technique [0002] As the information system becomes more and more complex, the system needs more and more services and middleware. It is necessary to uniquely identify a large amount of data and messages. When the amount of business data is not large, business can be generated in various ways. ID is mainly realized by auto-incrementing ID. The ID of the current business system uses the self-incrementing field of the database completely dependent on the database. However, in a large complex system, orders, products, and after-sales may be divided into databases and tables, and will be distributed in multiple tables and multiple databases, resulting in a large number of Duplicate IDs make business problematic. That is, for large-scale complex business and distributed high-concurrency ap...
