Abstract

The present application relates to a multi-threaded data processing method, device and storage medium based on a streaming computing framework. The first processing result is obtained by triggering the target window to process data slices based on the preset first water level; if the unprocessed data If there is a lag data slice whose event timestamp is less than the end timestamp of the target window in the slice, record the system timestamp of the streaming computing framework receiving the lag data slice; set the second watermark, where the delay time of the second watermark is not less than The difference between the system timestamp of the hysteresis data slice and the end timestamp of the target window; retrigger the target window to process the data slice based on the second watermark, obtain the second processing result, and correct the first processing result according to the second processing result, solving the problem Based on the inaccurate calculation results of the streaming computing framework, the accuracy of the calculation results is improved while ensuring a certain timeliness of data processing.

Description

technical field [0001] The present application relates to the technical field of big data processing, in particular to a multi-threaded data processing method based on a streaming computing framework, an electronic device and a storage medium. Background technique [0002] Usually in a big data system, using Flink to process real-time data is a better choice. Flink is a streaming computing framework for stateful computing on unbounded and bounded data streams. It can run in a cluster environment and perform computations on real-time data at memory execution speed and at any scale. There are three time concepts in Flink, namely event time stamp (Event Time), intake time stamp (Ingestion Time) and system time stamp (Processing Time). The event timestamp represents the time generated in the objective world. For example, a log is generated when a user clicks on a web page; the ingestion timestamp represents the time when the log reaches Flink; the system timestamp represents th...
