Problems solved by technology

[0003] In the prior art, the front node is used to read and forward the data to each processing node, and then each processing node performs ETL processing on the data read by the front node. However, in this method, the front node is used as the entrance Nodes have I / O performance bottlenecks, cannot process massive data or have difficulties in processing massive data

Abstract

The embodiment of the invention provides a data processing method, a node and an ETL (extract transform and load) system. The method comprises the steps of: a preposed node obtains file names and storage paths of multiple files corresponding to data to be processed from a source data source; the advanced node evenly distributes the file names and the storage paths of multiple files to each ETL processing node in a plurality of ETL processing nodes; and therefore each ETL processing node obtains data to be processed in a file corresponding to the received filename from the source data source according to the received storage path. According to the data processing method, the node and the ETL (extract transform and load) system, the capability of the ETL system on processing mass data is improved.

Description

technical field [0001] The invention relates to information technology, in particular to a data processing method, a node and an extraction, conversion and loading ETL system. Background technique [0002] In information and communication systems, it is often necessary to dump data into the file system, text transfer protocol (File Transfer Protocol, FTP) or network file system (Network File System, NFS), and each node in the network performs data extraction, loading and processing. Conversion (Extract Load Transform, ETL) processing. [0003] In the prior art, the front node is used to read and forward the data to each processing node, and then each processing node performs ETL processing on the data read by the front node. However, in this method, the front node is used as the entrance Nodes have I / O performance bottlenecks, cannot process massive data or have difficulties in processing massive data. Contents of the invention [0004] The embodiment of the present inve...
