Problems solved by technology

[0004] When the following two scenarios exist (1. The network environment where the data exchange system and the destination database are located is poor or the network is abnormal, such as network jitter or packet loss, the data exchange system submits data to the destination database, and the destination database loads data successfully, but the destination database returns 2. When the performance of the destination database itself is poor or the resource utilization rate is very high, if the data is not successfully written for a long time), it will cause the data exchange system to wait for a long time, waste resources, and finally submit the data It will fail, and the data needs to be submitted again, resulting in low exchange efficiency

Abstract

The embodiment of the invention provides a data exchange control method and device. According to the embodiment of the invention, after the first information is received, the received data volume corresponding to the current data exchange operation of the working node is obtained from a destination database, and the data submission of the current data exchange operation is controlled according tothe received data volume and the submitted data volume corresponding to the current data exchange operation, therefore, the restart frequency of a data submission task is reduced, the exchange time ofthe whole data exchange is reduced, and the exchange efficiency of a data exchange system is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data exchange control method and device. Background technique [0002] The ETL (Extract-Transform-Load, Extract-Transform-Load) system, also known as the data exchange system, is used to extract, transform, and load data from the source to the destination. In order to improve the ability of ETL exchange and support more data source access, ETL tools will be deployed in the form of clusters, and the control node will manage multiple work nodes in a unified manner, and assign data exchange jobs to one or more work nodes for data processing. exchange. [0003] According to the data exchange job issued by the control node and its parameter settings, the working node extracts data from the source database, and submits the data to the destination database after its own processing. [0004] When the following two scenarios exist (1. The network environment where the data exc...
