tIngresOutputBulk – Docs for ESB 7.x

tIngresOutputBulk

Prepares the file whose data is inserted in bulk to the Ingres
DBMS for performance gain.

tIngresOutputBulk and tIngresBulkExec
are generally used together in a two step process. In the first step, an output file is
generated. In the second step, this file is used in the INSERT operation used to feed a
database. These two steps are fused together in the
tIngresOutputBulkExec component.

tIngresOutputBulk prepares a file with the schema
defined and the data coming from the preceding component.

tIngresOutputBulk Standard properties

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

The Standard
tIngresOutputBulk component belongs to the Databases family.

The component in this framework is available in all Talend
products
.

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

Database

Select a type of database from the list and click
Apply.

Property Type

Either Built-in or
Repository
.

 

Built-in: No property data stored
centrally.

 

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

File Name

Name of the file to be generated.

Warning:

This file is generated on the local machine or a shared folder
on the LAN.

Append the File

Select this check box to add the 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
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.

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

 

Click Edit
schema
to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • 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.

Advanced settings

Field Separator

Character, string or regular expression to separate fields.

Row Separator

String (ex: ”
“on Unix) to separate rows.

Include Header

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

Encoding

List of encoding schemes.

tStatCatcher Statistics

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

Global Variables

Global Variables 

NB_LINE: the number of rows processed. This is an After
variable and it returns an integer.

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

For further information about variables, see
Talend Studio

User Guide.

Usage

Usage rule

Deployed along with tIngresBulkExec, tIngresOutputBulk is intended to save the incoming
data to a file, whose data is then inserted in bulk to an Ingres
database by tIngresBulkExec for
performance gain.

Limitation

Due to license incompatibility, one or more JARs required to use
this component are not provided. You can install the missing JARs for this particular
component by clicking the Install button
on the Component tab view. You can also
find out and add all missing JARs easily on the Modules tab in the
Integration
perspective of your studio. You can find more details about how to install external modules in
Talend Help Center (https://help.talend.com)
