Table Name

Specify the name of the table to be written. Note that only one table can be written at a time.

Action on table

On the table defined, you can perform one of the following operations:

  • None: No operation is carried out.

  • Drop and create table: The table is removed and created again.

  • Create table: The table does not exist and gets created.

  • Create table if not exists: The table is created if it does not exist.

  • Drop table if exists and create: The table is removed if it already exists and created again.

  • Clear table: The table content is deleted. You have the possibility to rollback the operation.

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.

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.

Data file path at local

Specify the local path to the file to be generated.

Note that the file is generated on the same machine where Talend Studio is installed or where the Job using this component is deployed.

Append the local file

Select this check box to append data to the specified local file if it already exists, instead of overwriting it.

Create directory if not exists

Select this check box to create the directory specified in the Data file path at local field if it does not exist. By default, this check box is selected.

Use an existing S3 connection

Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.

Information noteNote: This component works with static credentials only. That is, it does not inherit credentials from AWS role. The component will generate an error in Job execution if any option other than Static Credentials is selected from the Credential Provider drop-down list of the tS3Connection component that creates the S3 connection.

Credential provider

Specify the way to obtain AWS security credentials: Static Credentials, which uses access key and secret key as the AWS security credentials.

Information noteNote: This component works with static credentials only. That is, it does not inherit credentials from AWS role. The component will generate an error in Job execution if you select the Inherit credentials from AWS role option.

Access Key

Specify the Access Key ID that uniquely identifies an AWS Account. For how to get your Access Key and Access Secret, visit Getting Your AWS Access Keys.

Information noteNote: This option is available when Use an existing S3 connection is not selected or Inherit credentials from AWS role is not selected from the Credentials provider drop-down list.

Secret Key

Specify the Secret Access Key, constituting the security credentials in combination with the access Key.

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

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 Use an existing S3 connection is not selected.
  • Role ARN: the Amazon Resource Name (ARN) of the role to assume. You can find this ARN name on the Summary page of the role to be used on your AWS portal, for example, this role ARN could read like am:aws:iam::[aws_account_number]:role/[role_name].

    Role session name: enter the name you want to use to uniquely identify your assumed role session. This name can contain upper- and lower-case alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@-.
  • Session duration (minutes): the duration (in minutes) for which you want the assumed role session to be active. This duration cannot exceed the maximum duration which your AWS administrator has set. The duration defaults to 3600 seconds if you give it no value.

For an example about an IAM role and its related policy types, see Create and Manage AWS IAM Roles from the AWS documentation.

Region

Specify the AWS region by selecting a region name from the list or entering a region between double quotation marks (e.g. "us-east-1") in the list. For more information about the AWS Region, see Regions and Endpoints.

Information noteNote: This field is available when Use an existing S3 connection is not selected.

Bucket

Type in the name of the Amazon S3 bucket, namely the top level folder, to which the file is uploaded.

The policies must exist in the same account as the role. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies.

For more information about session policies, see the corresponding section in Policies and Permissions

This field is available only when the S3 Assume Role check box is selected.

Policy

Enter an IAM policy in JSON format that you want to use as a session policy. Use session policies to limit the permissions of the session. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies.

For more information about session policies, see the corresponding section in Policies and Permissions

This field is available only when the S3 Assume Role check box is selected.

JDBC url
Select a way to access to an Amazon Redshift database from the JDBC url drop-down list.
  • Standard: Use the standard way to access the Redshift database.
  • SSO: Use the IAM Single Sign-ON (SSO) authentication way to access the Redshift Database. Before selecting this option, ensure that the IAM role added to your Redshift cluster has appropriate access rights and permissions to this cluster. You can ask the administrator of your AWS services for more details.

    This option is available only when Use an existing connection check box is not selected from the Basic settings.

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.

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 more information about variables, see Using contexts and variables.

Usage

Usage rule

This component is mainly used when no particular transformation is required on the data to be loaded to Amazon Redshift.

Dynamic settings

Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your database connection dynamically from multiple connections planned in your Job. This feature is useful when you need to access database tables having the same data structure but in different databases, especially when you are working in an environment where you cannot change your Job settings, for example, when your Job has to be deployed and executed independent of Talend Studio.

The Dynamic settings table is available only when the Use an existing connection check box is selected in the Basic settings view. Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable.

For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Dynamic schema and Creating a context group and define context variables in it.
