tAmazonMysqlCommit – Docs for ESB 7.x


Commits in one go a global transaction instead of doing that on every row or
every batch, and provides gain in performance, using a unique connection.

tAmazonMysqlCommit validates the data processed through
the Job into the connected database.

tAmazonMysqlCommit Standard properties

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

The Standard
tAmazonMysqlCommit component belongs to the Cloud and the Databases families.

The component in this framework is available in all Talend

Note: This component is a specific version of a dynamic database
connector. The properties related to database settings vary depending on your database
type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings


Select a type of database from the list and click

Component list

Select the tAmazonMysqlConnection
component in the list if more than one connection are planned for
the current job.

Close Connection

This check box is selected by default. It allows you to close the
database connection once the commit is done. Clear this check box to
continue to use the selected connection once the component has
performed its task.


If you want to use a Row > Main connection to link tAmazonMysqlCommit to your Job,
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 your first row commit.

Advanced settings

tStatCatcher Statistics

Select this check box to collect log data at the component

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

For further information about variables, see
Talend Studio

User Guide.


Usage rule

This component is more commonly used with other tAmazonMysql*
components, especially with the tAmazonMysqlConnection and tAmazonMysqlRollback components.

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
view becomes unusable.

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