tAmazonAuroraConnection Properties

Component family



This component opens a connection to an Amazon Aurora database


This component allows you to open a connection to an Amazon Aurora
database instance that can then be reused by other Amazon Aurora

Basic settings

Property Type

Either Built-In or Repository.

Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.



Built-In: No property data stored



Repository: Select the repository
file in which the properties are stored. The database connection
fields that follow are completed automatically using the data



Type in the IP address or hostname of the Amazon Aurora



Type in the listening port number of the Amazon Aurora



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, and then in the pop-up dialog box enter the password between double quotes
and click OK to save the settings.


Use or register a shared DB Connection

Select this check box
to share your connection or use a connection shared by a parent or
child Job. This allows you to share one single connection among
several connection components from different Job levels that can be
either parent or child.


This option is incompatible with the Use dynamic job
and Use an independent process to run subjob options of
the tRunJob component. Using a shared connection
together with a tRunJob component with either of these
two options enabled will cause your Job to fail.

This check box disappears when the Specify a
data source alias
check box is selected.


Shared DB Connection Name

Type in the shared connection name.

This field appears only when the Use or
register a shared DB Connection
check box is


Specify a data source alias

Select this check box and specify the alias of a data source created on the Talend Runtime side to use the shared connection pool defined in the data source configuration.
This option works only when you deploy and run your Job in Talend Runtime.

This check box disappears when the Use or
register a shared DB Connection
check box is


Data source alias

Type in the alias of the data source created on the Talend Runtime side.

This field appears only when the Specify a
data source alias
check box is selected.

Advanced settings

Auto Commit

Select this check box to commit any changes to the database automatically upon the

With this check box selected, you cannot use the corresponding commit component to commit
changes to the database; likewise, when using the corresponding commit component, this check
box has to be cleared. By default, the auto commit function is disabled and changes must be
committed explicitly using the corresponding commit component.

Note that the auto commit function commits each SQL statement as a single transaction
immediately after the statement is executed while the commit component does not commit only
until all of the statements are executed. For this reason, if you need more room to manage
your transactions in a Job, it is recommended to use the commit component.

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 +
to access the variable list and choose the variable to use from it.

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


This component is more commonly used with other Amazon Aurora
components, especially with the tAmazonAuroraCommit and tAmazonAuroraRollback components.


The activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User

For more information on the log4j logging levels, see the Apache documentation at
