Abstract

The invention provides a method, a device, a system and a medium for generating an identifier. The method for generating the identifier comprises the following steps of obtaining first time information representing generation time of a first identifier, obtaining identification information used for generating an instance of the first identifier, obtaining a serial number of the first identifier, and generating the first identifier based on the first time information, the identification information of the instance and the serial number of the first identifier. The invention further provides a method, a device, a system and a medium for generating the identifier. The method for generating an identifier includes that a request is received to generate an identifier for a specific service, in response to the request, one or more instances for providing an identifier generation service for the particular service are determined, and an identifier is generated by one of the one or more instances according to the identifier generation method provided by the present disclosure.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and more specifically, to a method, device, system and medium for generating an identifier, and a method, device, system and medium for generating an identifier. Background technique [0002] Almost all systems need to uniquely identify a large amount of data and messages. UUID (Universally Unique Identifier, Universally Unique Identifier) ​​or the self-growth identification mechanism of the MySQL database are commonly used in existing identifier generation schemes. [0003] In the process of realizing the concept of the present disclosure, the inventor found at least the following problems in the prior art: UUID is a hexadecimal string, not an integer, the field is relatively long, it is not easy to be an index field of the database, and the string cannot be sorted , and the incremental trend of generated identifiers cannot be guaranteed; the performance of generating identifiers ...
