These properties are used to configure tPaloDimensionList running in the Standard Job framework.

The Standard tPaloDimensionList component belongs to the Business Intelligence family.

The component in this framework is available in all Talend products.

Basic settings

Use an existing connection

Select this check box and in the Component List click the relevant connection component to reuse the connection details you already defined.

Note that when a Job contains the parent Job and the child Job, Component List presents only the connection components in the same Job level.

Host Name

Enter the host name or the IP address of the host server.

Server Port

Type in the listening port number of the Palo server.

Username and Password

Enter the Palo user authentication data.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Database

The name of the database where the dimensions of interest reside.

Retrieve cube dimensions

Select this check box to retrieve dimension information from an existing cube.

Cube

Note:

Available when you select the Retrieve cube dimensions check box.

Type in the name of the cube from which dimension information is retrieved.

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to Repository. When you create a Spark Job, avoid the reserved word line when naming the fields.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this option to view the schema only.

  • Change to built-in property: choose this option to change the schema to Built-in for local changes.

  • Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the [Repository Content] window.

 

Built-in: The schema is created and stored locally for this component only. Related topic: see Talend Studio User Guide.

 

Repository: The schema already exists and is stored in the Repository, hence can be reused. Related topic: see Talend Studio User Guide.

Advanced settings

tStat Catcher Statistics

Select this check box to collect log data at the component level.

Global Variables

Global Variables

DIMENSIONNAME: the name of the dimension. This is a Flow variable and it returns a string.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.
