tVerticaOutputBulk – Docs for ESB 7.x


Prepares a file to be used by the tVerticaBulkExec component to
feed a Vertica database.

The tVerticaOutputBulk
component and the tVerticaBulkExec component are generally used together as
parts of a two step process. In the first step, an output file is generated. In the second
step, the file is used in a bulk load operation to feed a database. These two steps are fused
together in the tVerticaOutputBulkExec component. The advantage of using
two separate components is that the data can be transformed before it is loaded into the

tVerticaOutputBulk Standard properties

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

The Standard
tVerticaOutputBulk component belongs to the Databases family.

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

Property Type

Select the way the file path and the schema will be set.

  • Built-In: The file path and the schema will be
    set locally for this component.

  • Repository: The file details stored centrally
    in Repository > Metadata will be reused by this component. You need to click
    the […] button next to it and in the pop-up
    Repository Content dialog box, select the
    file to be reused, and all related properties will be automatically
    filled in.

File Name

The path to the file to be generated.

This file is generated on the same machine where your Studio is installed or where your
Job using this component is deployed.


Select this check box to add new rows at the end of the file.

Schema and Edit schema

A schema is a row description. It defines the number of fields
(columns) to be processed and passed on to the next component. When you create a Spark
Job, avoid the reserved word line when naming the

  • Built-In: You create and store the schema locally for this component

  • Repository: You have already created the schema and stored it in the
    Repository. You can reuse it in various projects and Job designs.

When the schema to be reused has default values that are
integers or functions, ensure that these default values are not enclosed within
quotation marks. If they are, you must remove the quotation marks manually.

You can find more details about how to
verify default values in retrieved schema in Talend Help Center (https://help.talend.com).

Click Edit
to make changes to the schema.

Note: If you
make changes, the schema automatically becomes built-in.
  • View schema: choose this
    option to view the schema only.

  • Change to built-in property:
    choose this option to change the schema to Built-in for local changes.

  • Update repository connection:
    choose this option to change the schema stored in the repository and decide whether
    to propagate the changes to all the Jobs upon completion. If you just want to
    propagate the changes to the current Job, you can select No upon completion and choose this schema metadata
    again in the Repository Content

Advanced settings

Row Separator

The separator used to identify the end of a row.

Include Header

Select this check box to include the column header to the file.


Select an encoding method from the list, or select

variable and it returns a string.


Usage rule

This component is more commonly used with the tVerticaBulkExec component. Used together, they
offer gains in performance while feeding a Vertica database.

Talend Studio and the
Vertica database create very fast and affordable data warehouse and data mart applications.
