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

The Standard tBigQueryOutputBulk component belongs to the Big Data 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.

Property type

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.

File name

Browse, or enter the path to the .txt or .csv file you need to generate.

Append

Select the check box to write new data at the end of the existing data. Otherwise, the existing data will be overwritten.

Advanced settings

Field Separator

Enter character, string or regular expression to separate fields for the transferred data.

Create directory if not exists

Select this check box to create the directory you defined in the File field for Google Cloud Storage, if it does not exist.

Custom the flush buffer size

Enter the number of rows to be processed before the memory is freed.

Check disk space

Select the this check box to throw an exception during execution if the disk is full.

Encoding

Select the encoding from the list or select Custom and define it manually. This field is compulsory for database data handling. The supported encodings depend on the JVM that you are using. For more information, see https://docs.oracle.com.

tStatCatcher Statistics

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

Global Variables

Global Variables

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.

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 is an output component which needs the data provided by its preceding component.

This component automatically detects and supports both multi-regional locations and regional locations. When using the regional locations, the buckets and the datasets to be used must be in the same locations.
