DB Version

Select the version of the Vertica database being used.

Use an existing connection

Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.

ELT Vertica Map Editor

The ELT Map editor allows you to define the output schema as well as build graphically the SQL statement to be executed. The column names of the schema can be different from the column names in the database.

If you have installed the R2021-06 Studio monthly update or a later one provided by Talend, an Enable/disable column name filter button is available on the upper right corner of the input and output tables in the Map editor. You can filter schema columns in an input or output table by clicking this button in the corresponding table and entering the search keyword in the field displayed.

Style link

Select a 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: The links between the schema and the Web service parameters are in the form of curve.

• Line (fastest): The links between the schema and the Web service parameters are in the form of straight lines.

  This option slightly optimizes performance.

Either Built-In or Repository.

Built-In: No property data stored centrally.

tStatCatcher Statistics

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

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.

tELTVerticaMap is used along with tELTVerticaInput and tELTVerticaOutput. Note that the Output link to be used with these components must correspond strictly to the syntax of the table name.
