Select the desired database type from the list and click Apply.

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 Talend Studio is installed or where your Job using this component is deployed.

Append

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

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 fields.

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

• 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.

For more information, see Retrieving table schemas.

Click Edit schema to make changes to the schema. 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 window.

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.

Encoding

Select an encoding method from the list, or select CUSTOM and define it manually. This field is compulsory for database data handling.

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. For more information about how to configure Talend Studio to connect to Vertica, see Talend and HP Vertica Tips and Techniques.
