Abstract

The invention discloses a distributed global serial number implementation method and a sequence dispatcher. The method is applied to at least one sequence dispatcher in a distributed system, the distributed system further comprises a database and a sequence client, and the sequence dispatcher is connected with the database and the sequence client. The method comprises the steps that when the sequence dispatcher does not obtain a sequence from the database for the first time, sequence attributes and current sequence values of the sequence with the same ID are obtained from the database according to the ID of the sequence which is dispatched for the last time, wherein the sequence attributes comprise the sequence maximum value, the sequence minimum value, the step length, the cache number and whether circulation is supported or not; a sequence number is generated according to the sequence attribute and the sequence current value; and when a serial number distribution request of the sequence client is received, the generated serial numbers are distributed to the sequence client. The invention can provide a global serial number implementation scheme with low coding and configuration workload.

Description

technical field [0001] The invention relates to the technical field of distributed architecture, in particular to a method for realizing a distributed global serial number and a serial distributor. Background technique [0002] This section is intended to provide a background or context to 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] Under the distributed architecture, the problem of how to generate the unique serial number is a problem that is often encountered when designing various applications in a system, especially when the database uses sub-databases and sub-tables. When the database is divided into several sub-tables, how to quickly obtain a unique serial number for each table data in each sub-table is a problem that needs to be considered. [0004] The current mainstream solutions include Snowflake Algorithm, Redis Global Cache, etc. Snowflake Algorithm ...
