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

The Standard tPaloOutputMulti component belongs to the Business Intelligence family.

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

Basic settings

Use an existing connection

Select this check box and in the Component List click the relevant connection component to reuse the connection details you already defined.

Note that when a Job contains the parent Job and the child Job, Component List presents only the connection components in the same Job level.

Host Name

Enter the host name or the IP address of the host server.

Server Port

Type in the listening port number of the Palo server.

Username and Password

Enter the Palo user authentication data.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Database

Type in the name of the database where the cube of interest resides.

Cube

Type in the name of the cube in which the incoming data is written.

Cube type

Select the cube type from the drop-down list for the cube of concern. This type may be:

- Normal

- Attribut

- System

- User Info

Commit size

Type in the row count of each batch to be written into the cube.

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to Repository. When you create a Spark Job, avoid the reserved word line when naming the fields.

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.

 

Built-in: The schema is created and stored locally for this component only. Related topic: see Talend Studio User Guide.

 

Repository: The schema already exists and is stored in the Repository, hence can be reused. Related topic: see Talend Studio User Guide.

Measure value

Select the column from the input stream which holds the Measure or Text values.

Splash mode

Select the splash mode used to write data into a consolidated element. The mode may be:

- Add: it writes values to the underlying elements.

- Default: it uses the default splash mode.

- Set: it simply sets or replaces the current value and make the distribution based on the other values.

- Disable: it applies no splashing.

For further information about the Palo splash modes, see Palo's user guide.

Add values

Select this check box to add new values to the current values for a sum. Otherwise these new values will overwrite the current ones.

Use eventprocessor

Select this check box to call the supervision server.

Die on error

This check box is cleared by default, meaning to skip the row on error and to complete the process for error-free rows.

Advanced settings

tStat Catcher Statistics

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

Enable parallel execution

Select this check box to perform high-speed data processing, by treating multiple data flows simultaneously. Note that this feature depends on the database or the application ability to handle multiple inserts in parallel as well as the number of CPU affected. In the Number of parallel executions field, either:
  • Enter the number of parallel executions desired.

  • Press Ctrl + Space and select the appropriate context variable from the list. For further information, see Talend Studio User Guide.

  • The Action on table field is not available with the parallelization function. Therefore, you must use a tCreateTable component if you want to create a table.

  • When parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subjob.

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 + 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

This component requires an input component.

Connections

Outgoing links (from this component to another):

Trigger: Run if; On Component Ok; On Component Error.

Incoming links (from one component to this one):

Row: Main; Reject

For further information regarding connections, see Talend Studio User Guide.

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. For details, see Installing external modules.
