Abstract

The invention relates to a data identifier generation method and device, equipment and a storage medium, and relates to the field of data processing. The data identifier generation method comprises the following steps: receiving an identifier generation request sent by a client, wherein the identifier generation request carries an acquisition moment of current data and a user identifier to which the current data belongs; acquiring the acquisition moment and the user identifier from the identifier generation request; and generating a data identifier of the current data based on the acquisition moment and the user identifier. The method and the device are used for solving the problem that different identifiers are generated by the same piece of data in data processing.

Description

technical field [0001] The present application relates to the field of data processing, and in particular, to a method, apparatus, device and storage medium for generating a data identifier. Background technique [0002] In real-time streaming data processing, if it is based on Flink for real-time data processing, in the event of a failure, the Flink program with checkpointing enabled will resume processing from the last completed checkpoint during recovery. [0003] The existing identification (ID) generation method is to use self-incrementing sequence or timestamp. If the ID of the data is generated just before the checkpoint is restored, and the generated ID has also been stored in the database, it will be changed after the checkpoint is restored. The data regenerates the ID, and the regenerated ID must be inconsistent with the existing ID, which will cause the same data to have different IDs in the database, resulting in data redundancy and even data confusion.
