A method and apparatus for allocate service identifiers

Abstract

A method and apparatus for allocate service identifiers are provided in embodiments of that present application, A service identifier satisfying a preset condition is selected from a plurality of service identifiers according to a preset modulo operation in advance and stored in a local queue, and the preset conditions for different distributed service nodes are different, such that for a plurality of service identifiers obtained from different distributed service nodes, A service identifier selected by the service system for storing in a local queue is different from each other, after receiving the caller's assignment request, the service ID is directly selected from the local queue and assigned to the caller, and when the service identifiers in the local queue are assigned, The service identifier joining operation is executed again, so that even if the service system obtains the same service identifier from multiple distributed service nodes at the same time, the service identifier duplicate assignment can be avoided due to the introduction of the module selection mechanism, the high concurrency capability and the high availability of the system can be improved, and the effect ofglobal uniqueness and trend self-increasing can be achieved.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a method and device for allocating service identifiers. Background technique [0002] At present, with the rapid development of Internet technology, the growth rate of business data generated in the process of business processing is getting faster and faster. In order to facilitate the efficient management of business data, a unique identifier needs to be used for any business processing process Uniquely mark the generated business data. Specifically, when the business processing server processes the business request of the client, it needs to use a unique identifier to mark the generated business data. [0003] For example, in the case where the business processing server is an order system, after the shopping is completed, the order system generates the order data for this purchase. Before generating the order data, the order system requests the business system to assign...

Problems solved by technology

[0004] Wherein, for the service ID allocation process provided in the prior art, after the service system receives the caller's service ID allocation request, it obtains the service ID from the distributed service node, and then assigns the acquired service ID to the corresponding caller , in the case of a relatively large amount of requests, it is more difficult for multiple distributed service nodes to generate a distributed global unique self-incrementing business identifier, and it may happen that the business identifiers obtained by the business system from multiple distributed service nodes are the same , leading to the situation that the same business ID is assigned to multiple callers, resulting in the inability to guarantee the uniqueness of the business ID corresponding to the business data, and thus unable to meet the high concurrency and global uniqueness of the system
