Embodiment Construction

[0066] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0067] Currently, the producer device can send the produced data to the Kafka message queue to cache the data through the Kafka message queue. In addition, consumer devices can obtain data from the Kafka consumption queue for consumption. Among them, the Kafka message queue is a high-throughput distributed publish / subscribe message queue.

[0068] In addition, the consumer device can be configured: after successfully writing the read data, submit the offset (...

Abstract

The embodiment of the invention provides a data processing method, device and system, electronic equipment and a storage medium. The method comprises the steps: reading to-be-processed data in a preset data consumption queue, and executing a first preprocessing operation used for preprocessing the to-be-processed data, a second preprocessing operation used for pre-storing the to-be-processed dataand a third preprocessing operation used for pre-reporting offset, and when execution of at least one of the first preprocessing operation, the second preprocessing operation and the third preprocessing operation fails, recovering the data state to a state before the to-be-processed data are read from the preset data consumption queue. According to the embodiment of the invention, when the execution of at least one of the first, second and third preprocessing operations fails, the whole first, second and third preprocessing operations fail, so that the data consumption process meets the atomicity, and the problems of data loss and repeated data consumption caused by an automatic offset submitting mode are solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method, device, system, electronic equipment and storage medium. Background technique [0002] Currently, the producer device can send the produced data to the Kafka message queue to store the data through the Kafka message queue. In addition, consumer devices can obtain data from the Kafka consumption queue for consumption. Among them, the Kafka message queue is a high-throughput distributed publish / subscribe message queue. [0003] In addition, the consumer device can be configured: after successfully writing the read data, submit the offset (offset) corresponding to the read data to the Kafka consumption queue, that is, manually submit the offset to inform Kafka consumption Queue where this consumer device has read data. [0004] In the process of implementing the present invention, the inventor found that the consumer device may have the followi...
