Abstract

The invention discloses a multi-data-stream processing method and device, a terminal and a storage medium, and the method comprises the steps: receiving a plurality of data streams transmitted by message middleware, and obtaining the type of each data stream; extracting a first data stream of which the type is insertion in the plurality of data streams, and inserting the first data stream into a pre-constructed final result table by utilizing an Flink window function; extracting a second data stream of which the type is not inserted in the plurality of data streams, constructing a synchronization table, and inserting the second data stream into the synchronization table by utilizing an Flink window function; and combining the synchronization table with a pre-constructed final result tableto update corresponding fields in the final result table to obtain a new final result table. By means of the mode, under the condition that data integrity and accuracy are guaranteed, the Flink is used for processing multiple inserted or updated data volumes sent by the message-oriented middleware.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a multi-data stream processing method, device, terminal and storage medium. Background technique [0002] In the field of data processing, data processing methods can be divided into batch processing and stream processing in a certain way. Batch processing is about packaging a certain amount of data for unified processing. The calculation time is measurable and bounded, while stream processing is It is non-stop calculation, once the program is started, it will not stop, and the amount of data and time-consuming processing tasks will increase infinitely. [0003] The Flink framework is widely used in the field of streaming data and batch data processing, because Flink can be executed on a large scale, has very high throughput, and can provide correct results even in the case of out-of-order or data delays. Benefiting from Flink's excellent performance and exactl...
