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

The Standard tNormalize component belongs to the Processing family.

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

Basic settings

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.

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: 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.

Column to normalize

Select the column from the input flow which the normalization is based on.

Item separator

Enter the separator which will delimit data in the input flow.

Note:

The item separator is based on regular expressions, so the character "." (a special character for regular expression) should be avoided or used carefully here.

Advanced settings

Get rid of duplicated rows from output

Select this check box to deduplicate rows in the data of the output flow.

Use CSV parameters

Select this check box to include CSV specific parameters such as escape mode and enclosure character.

Discard the trailing empty strings

Select this check box to discard the trailing empty strings.

Trim resulting values

Select this check box to trim leading and trailing whitespace from the resulting data.

Note:

When both Discard the trailing empty string and Trim resulting values check boxes are selected, the former works first.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level as well as at each component level.

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.

NB_LINE: the number of rows read by an input component or transferred to an output component. This is an After variable and it returns an integer.

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.
