Transaction identifier processing method and device and electronic equipment

Abstract

The invention provides a transaction identifier processing method and device and electronic equipment, and relates to the technical field of computers. The method comprises the steps of receiving an acquisition request of a client for a transaction identifier; reading a transaction identifier currently pointed by a queue pointer from a preset first queue, and moving the queue pointer according toa preset step length, so that the queue pointer points to a next transaction identifier in the first queue, wherein a plurality of sequentially increasing transaction identifiers are pre-stored in thefirst queue; and returning the read transaction identifier to the client. According to the embodiment of the invention, a plurality of transaction identifiers which are sequentially increased are generated in advance and stored in the queue, and when the transaction identifier acquisition request of the client is received, the transaction identifiers are sequentially read from the queue and returned to the client, so that the transaction identifiers provided for the client are continuously increased, and the mode can meet the requirement of the client for the continuously increasing transaction identifier.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a transaction identification processing method, device and electronic equipment. Background technique [0002] The database auto-increment primary key means that the value of the id field is set to auto-increment when designing the table, so that when inserting a row of data, there is no need to specify the id, but the id value of the previous field is automatically increased by 1 for filling. For example, in a MySQL database, the sql statement AUTO_INCREMENT can be used to enable auto-increment assignment for a specific field, and the atomicity of the field can be guaranteed by using the auto-increment id as the primary key. [0003] In a distributed database system, distributed transactions need to be uniquely identified, and if each server node in the system independently obtains the transaction ID by using the database auto-increment primary key, many duplicate tran...
