Abstract

The present application discloses a method, device, device, and storage medium for generating a globally unique identifier. The method includes: presetting multiple timelines including one current timeline and at least one rollback timeline, and the time of the current timeline The progress advances with the time of the local clock, and the time progress of the rollback timeline is later than the time progress of the current timeline; when the request for generating the globally unique identifier of the target node is received, the clock state of the local clock is determined, and when the clock state is When the clock rolls back, determine the clock rollback time; when the clock rollback time is greater than or equal to the preset threshold, determine the target rollback timeline; determine the timestamp of the target node according to the time point after the clock rollback; determine the target rollback The identification information of the regression timeline, the node identification and serial number of the target node; the globally unique identifier is generated based on the node identification, serial number, time stamp of the target node and the identification information of the target regression timeline.

Description

technical field [0001] The present application relates to the technical field of Internet communication, and in particular to a method, device, device and storage medium for generating a globally unique identifier. Background technique [0002] A globally unique identifier is a relatively unique code in a certain system. The global consistency of distributed databases, the serialization of parallel operations, and the global recoverability of the system are all inseparable from globally unique identifiers. [0003] In the prior art, the snowflake (snowflake) algorithm is often used to generate a globally unique identifier. The snowflake algorithm uses a 64-bit integer to represent a globally unique identifier, which is divided into symbol bits, timestamps, node identifiers, and serial numbers. Specifically, such as figure 1 As shown, the first bit: 1bit (bit), sign bit, fixed to zero (because there is no unsigned number in some languages ​​or some databases, in order to en...
