Self-adaptive global sequence number generation method and device

Abstract

The invention provides a self-adaptive global sequence number generation method and device, and belongs to the distributed technology, and the method comprises the steps: enabling a request response subprogram to receive a global sequence number obtaining request sent by an external system; calling a global serial number cache management subprogram by a global serial number management subprogram to obtain a global unique serial number and the number of current remaining available serial numbers from the distributed cache; processing the global unique sequence number, and returning the processed global unique sequence number to a requested external system by a request response subprogram; enabling the global serial number management subprogram to asynchronously call a request statistical analysis subprogram to perform statistical analysis on the global serial number acquisition request, and determining a request quantity statistical analysis result; adjusting a cache capacity and a cache threshold value through a cache capacity control subprogram and a global serial number cache management subprogram; according to the number of the current remaining available serial numbers and the cache capacity and the cache threshold value of the distributed cache, loading the global unique serial numbers asynchronously and dynamically to the distributed cache in batches from the database through the global serial number batch management subprogram.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a method and device for generating an adaptive global sequence number. Background technique [0002] This section is intended to provide a background or context for the embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In a distributed system, there are typical scenarios where a globally unique serial number needs to be generated during a transaction to uniquely identify key objects. Generally speaking, the generation of the globally unique serial number is realized by means of storage such as database and distributed cache during the construction of the system. The uniqueness of the globally unique serial number and the efficiency of generation are two important aspects to measure the quality of the generation method. [0004] At present, the common glob...
