tSnowflakeOutputBulk Standard properties

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

The Standard tSnowflakeOutputBulk component belongs to the Cloud family.

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

This field is available only when you select Use this Component from the Connection Component drop-down list and select Internal from the Storage drop-down list in the Basic settings view.

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.

If the Snowflake data type to be handled is VARIANT, OBJECT or ARRAY, while defining the schema in the component, select String for the corresponding data in the Type column of the schema editor wizard.

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.

Note that if the input value of any non-nullable primitive field is null, the row of data including that field will be rejected.

This component offers the advantage of the dynamic schema feature. This allows you to retrieve unknown columns from source files or to copy batches of columns from a source without mapping each column individually. For further information about dynamic schemas, see Talend Studio User Guide.

This dynamic schema feature is designed for the purpose of retrieving unknown columns of a table and is recommended to be used for this purpose only; it is not recommended for the use of creating tables.

S3 assume role

If you temporarily need some access permissions associated to an AWS IAM role that is not granted to your user account, select this check box to assume that role. Then specify the values for the following parameters to create a new assumed role session.

Ensure that access to this role has been granted to your user account by the trust policy associated to this role. If you are not certain about this, ask the owner of this role or your AWS administrator.

Information noteNote:
  • This option is available when S3 is selected from the Storage drop-down list in the Basic settings view.
  • This option is available only when you have installed the R2021-10 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.

Non-empty Storage Folder Action Specify the action to be performed when the storage folder specified for uploading data is not empty.
  • Add New Files: continues to process the Job and adds new files to the folder.
  • Cancel Upload: stops the operation.
  • Replace Existing Files: cleans the storage folder before adding new files.
Chunk Size (bytes) Specify the size for the files generated, which defaults to 52428800 bytes.

With this option specified, the incoming data may be stored in multiple files. Since data is stored in files on a record base, the actual size of each file generated can be larger or smaller than the specified value, but no more than the size of the last record stored in the file.

This option can significantly affect the performance. So set it carefully. See File Sizing Best Practices and Limitations for related information.
Use Custom Local Folder Specify a local folder as a temporary folder for holding the files generated. With this option selected, files for storing the incoming data are first generated in the specified local folder and are then moved to the specified storage after all the incoming data is uploaded.
