DataWorks provides MaxCompute Reader and MaxCompute Writer for you to read data from and write data to MaxCompute data sources.
Background information
MaxCompute provides a comprehensive data import scheme that helps achieve fast computing of large amounts of data. If you associate a MaxCompute compute engine instance with a workspace for the first time, DataWorks generates the default data source odps_first for the workspace. Each time you associate a new MaxCompute compute engine instance with the workspace, DataWorks generates a compute engine data source named in the format of 0_Region ID_Compute engine instance name.
- You can change only the AccessKey pair of one Alibaba Cloud account to that of another Alibaba Cloud account.
- Before you change the AccessKey pair, make sure that no Data Integration or DataStudio nodes are running in DataWorks. You can use a RAM user to access the MaxCompute data sources that you add.
