Read MaxCompute Table

Last Updated: Aug 16, 2021

The Read MaxCompute Table component reads data from MaxCompute tables. By default, it reads the table data of the current project. To read data from tables across projects, you must prefix the table names with the related project names.

Machine Learning Studio allows you to configure the Read MaxCompute Table component only in the Machine Learning Platform for AI (PAI) console. The following table describes the parameters that are used to configure the component.

Tab

Parameter

Description

Table Selection

Table Name

The name of the MaxCompute table from which you want to read data. If you want to read data from a MaxCompute table in another project, set this parameter in the Project name.Table name format, such as tianchi_project.weibo_data.

Notice

If the fields in the MaxCompute table are modified, the modifications cannot be synchronized to Machine Learning Studio. You must manually configure the MaxCompute data source again.

Partition

If the input table is a partitioned table, the system automatically selects Partition.

Parameter

The specific partition. You can specify only one partition. Set this parameter in the dt=@@{yyyyMMdd} or dt=@@{yyyyMMdd-1d} format. @@{yyyyMMdd} indicates the current date and @@{yyyyMMdd-1d} indicates the day before the current date. If you do not specify a value for this parameter, the full table is specified.

Source Table Columns

After you set the Table Name parameter, the system automatically reads the table schema.
