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

The Standard tELTGreenplumMap component belongs to the ELT 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: When a Job contains the parent Job and the child Job, if you need to share an existing connection between the two levels, for example, to share the connection created by the parent Job with the child Job, you have to:
  1. In the parent level, register the database connection to be shared in the Basic settings view of the connection component which creates that very database connection.

  2. In the child level, use a dedicated connection component to read that registered database connection.

For an example about how to share a database connection across Job levels, see Talend Studio User Guide.

ELT Greenplum Map Editor

The ELT Map editor allows you to define the output schema and make a graphical build of the SQL statement to be executed. The column names of schema can be different from the column names in the database.

Style link

Select the way in which links are displayed.

Auto: By default, the links between the input and output schemas and the Web service parameters are in the form of curves.

Bezier curve: Links between the schema and the Web service parameters are in the form of curve.

Line: Links between the schema and the Web service parameters are in the form of straight lines.

This option slightly optimizes performance.

Property type

Either Built-in or Repository.

 

Built-in: No property data stored centrally.

 

Repository: Select the Repository file where Properties are stored. The following fields are pre-filled in using fetched data.

Host

Database server IP address.

Port

Listening port number of DB server.

Database

Name of the database.

Username and Password

DB 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.

Advanced settings

Additional JDBC parameters

Specify additional connection properties for the DB connection you are creating. This option is not available if you have selected the Use an existing connection check box in the Basic settings.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a Job level as well as at each component level.

Global Variables

Global Variables

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.

Usage

Usage rule

tELTGreenplumMap is used along with tELTGreenplumInput and tELTGreenplumOutput. Note that the Output link to be used with these components must correspond strictly to the syntax of the table name.

Note:

Note that the ELT components do not handle actual data flow but only schema information.

Dynamic settings

Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your database connection dynamically from multiple connections planned in your Job. This feature is useful when you need to access database tables having the same data structure but in different databases, especially when you are working in an environment where you cannot change your Job settings, for example, when your Job has to be deployed and executed independent of Talend Studio .

The Dynamic settings table is available only when the Use an existing connection check box is selected in the Basic settings view. Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable.

For examples on using dynamic parameters, see Scenario: Reading data from databases through context-based dynamic connections and Scenario: Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Talend Studio User Guide.
