Distributed digital ID generation algorithm

Abstract

The invention discloses a distributed digital ID generation algorithm. The algorithm comprises the following steps: a program is started; an instance number of the ID generator is read from a database; if the instance number of the read ID generator does not exist, a new number is generated from the instance number which does not exist; a new number is generated and written into a database; if the instance number of the read ID generator exists, the starting is ended; a request of a user firstly arrives at the request dispatcher; the request dispatcher guides the request to a certain node in the ID generator cluster according to a distribution algorithm; the ID generator instance generates an ID and then returns a result to the request distributor; and the request distributor returns the result to the user. The method has the advantages that 1, ID generation can be used for distributed deployment by using a distributed algorithm, the ID generation speed can be increased and the ID generation quantity can be increased by increasing the quantity of deployed servers, and meanwhile, the quantity of calling customer service sides can also be increased; and 2, the ID generation algorithm is deployed on a plurality of servers, so that the availability of ID generation and the number of generated IDs can be enhanced.

Description

technical field [0001] The invention relates to a distributed digital ID generation algorithm, which belongs to the technical field of data storage systems. Background technique [0002] In a distributed system, it is necessary to ensure that certain business data identification fields uniquely exist in the entire distributed system. For example, a user executes an action on a function module on the system and generates an event. This event is subscribed by other modules of the system. In order to identify a specific event, an ID field needs to be added to the event field, and the value generated by the ID generation algorithm should be assigned. In the existing technology, the digital ID generation algorithm cannot guarantee that some business data identification fields uniquely exist in the entire distributed system, for example, a user performs an action on a functional module on the system to generate an event. This event is subscribed by other modules of the system. I...

In the existing technology, the digital ID generation algorithm cannot guarantee the unique existence of certain business data identification fields in the entire distributed system. For example, when a user performs an action on a functional module in the system, an event is generated

This event is subscribed by other modules of the system. In order to identify the specific event, it is necessary to add an ID field to the event field and assign the value generated by the ID generation algorithm, which will not achieve a good use effect, and the ID generation algorithm generates There is a situation where the ID exceeds the maximum value of the Number data type of the JavaScript programming language
