Abstract

The invention provides an identifier generation method, system and device based on a distributed system and a medium, and the method comprises the steps: obtaining one or more identifier generation requests, and enabling the identifier generation requests to comprise a business KEY value; detecting whether the number of the remaining identifiers in the current cache meets the requirements of the identifier generation request or not; when the number of the remaining identifiers in the cache meets the requirement of an identifier generation request, returning the identifiers to a requester; whenthe number of the remaining identifiers in the cache does not meet the requirement of an identifier generation request, calling a Redis INCR instruction to generate an identifier, and returning the identifier to the cache to meet the identifier generation request; and obtaining the maximum value of the sequence by utilizing the Redis INCR, reversely calculating the initial values to be sequentially increased or decreased to generate identifiers, and determining the generation quantity of the identifiers according to the quantity of the remaining identifiers in the cache and the requirements of identifier generation requests. According to the invention, the identifier generation efficiency is improved; the ID repetition phenomenon is avoided through the sequence IDs generated in sequence,and subsequent capacity expansion is facilitated.

Description

technical field [0001] The present application relates to the computer field, and in particular to a method, system, device and medium for generating an identifier based on a distributed system. Background technique [0002] In some scenarios of Internet and software development, all data objects need a unique identification (Identification, ID), and the service used to generate the ID is called an ID generator (or ID generator). The ID generator includes issuing globally unique IDs for data objects or other services. Data objects can only be stored and used after being assigned an ID. [0003] Existing ID generators ensure the uniqueness of data based on the self-incrementing sequence of the database or UUID (Universal Unique Identification Code). However, when the data reaches a certain level, the system will be upgraded to a distributed cluster architecture. On the one hand, if you continue to use the auto-increment sequence, it will limit the expansion of the database ...
