tVectorWiseCommit – Docs for ESB 5.x

Component family

Databases/VectorWise

Function

tVectorWiseCommit validates the data processed in a Job
into the connected DB.

Purpose

Using a single connection, this component commits a global
transaction in one go instead of doing so on every row or every
batch. This provides a gain in performance

Note that if you need to commit each statement as an individual transaction, you have to use
the Auto Commit function available in the connection
component.

Basic settings

Component list

Select the tVectorWiseConnection
component from the list if more than one connection is 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.

Advanced settings

tStatCatcher Statistics

Select this check box to collect log data at the component
level.

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.

Once a dynamic parameter is defined, the Component List
box in the Basic settings view becomes unusable.

For more information on Dynamic settings and context
variables, see Talend Studio User Guide.

Usage

This component is more commonly used with other tVectorWise*
components, especially with the tVectorWiseConnection and tVectorWiseRollback components.
