Abstract

The embodiment of the invention provides a serial number generation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a serial number generation request initiated by a target business, wherein the serial number generation request comprises a node identification corresponding to the target business; generating a current counting serial number according to a historical counting serial number which is a counting serial number generated in response to the last serial number generation request; and generating a target serial number accordingto the current timestamp, the current counting serial number and the node identifier, wherein the target serial number is used for uniquely identifying the target service. In the scheme, the countingserial number is irrelevant to the timestamp, namely, when the time rolls back, the counting serial number is continuously increased and is not reset to the minimum value, so that the serial number generated by the method can tolerate certain time roll-back.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a serial number generation method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid development of computer technology, more and more technologies are applied in the financial field, and the traditional financial industry is gradually transforming into financial technology (Fintech). However, due to the security and real-time requirements of the financial industry, more and more technical requirements high demands. [0003] For the distributed computer system used to support various financial services, it is necessary to generate a globally unique serial number to uniquely identify a large amount of transaction information in the distributed computer system. Among them, the common serial number generation method includes the Snowflake (Snowflake) algorithm. [0004] However, when the existing snowfl...
