tELTVerticaMap Standard properties

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

The Standard tELTVerticaMap component belongs to the ELT family.

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

Basic settings

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. Information noteNote: When a Job contains the parent Job and the child Job, do the following if you want to share an existing connection between the parent Job and the child Job (for example, to share the connection created by the parent Job with the child Job). 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. 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 Sharing a database connection.
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. You can filter schema columns in an input or output table by clicking the Enable/disable column name filter button in the corresponding table and entering the search keyword in the field displayed. You can click on the upper left corner and in the Property Settings dialog box displayed, select the Add quotes in columns when generating query check box to add quotes for the column names in the generated SQL query. This check box is displayed as Delimited identifiers if you have not installed the 8.0 R2022-11 Talend Studio monthly update or a later one provided by Talend.
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.
Property Type	Either Built-In or Repository.
	Built-In: No property data stored centrally.
	Repository: Select the repository file in which the properties are stored. The database connection fields that follow are completed automatically using the data retrieved.
Host	Type in the IP address or hostname of the database.
Port	Type in the listening port number of the database.
Database	Type in the name of the database you want to use.
Additional JDBC Parameters	Specify additional connection properties for the database connection you are creating.
Username and Password	Type in the database user authentication data. To enter the password, click the [...] button next to the password field, enter the password in double quotes in the pop-up dialog box, and click OK to save the settings.

Advanced settings

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

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 more information about variables, see Using contexts and variables.

Usage

Usage rule	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. Information noteNote: The ELT components do not handle actual data flow but only schema information.
