Component List

Select the component in which the relevant reused database connection is
configured.

Close Connection

Select this check box to close the database connection once the component has performed
its task.

Clear this check box to continue to use the selected connection once the component has
performed its task.

If this component is linked to your Job via a Row > Main connection, your data will be committed row by row. In this case, do not
select the Close connection check box or your
connection will be closed before the end of the first row commit.

tStatCatcher Statistics

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

Usage rule

This component is more commonly used with other tVertica*
components, especially with the tVerticaConnection and tVerticaRollback components.

Talend Studio and the
Vertica database create very fast and affordable data warehouse and data mart applications.
For more information about how to configure
Talend Studio
to connect to Vertica, see Talend and HP Vertica Tips and
Techniques.

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
.

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.
