tRedshiftOutputBulk Standard properties

Select the desired database type from the list and click Apply.

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.

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.

Compress the data file

Select this check box and select a compression type from the list displayed to compress the data file.

This check box disappears when the Append the local file check box is selected.

Encrypt

Select this check box to generate and upload the data file to Amazon S3 using client-side encryption. In the Encryption key field displayed, enter the encryption key used to encrypt the file.

By default, this check box is cleared and the data file will be uploaded to Amazon S3 using server-side encryption.

For more information about the client-side and server-side encryption, see Protecting Data Using Encryption.

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.

Credential provider

Specify the way to obtain AWS security credentials: Static Credentials or Inherit credentials from AWS role.

• Static Credentials: Use access key and secret key as the AWS security credentials.
• Inherit credentials from AWS role: Obtain AWS security credentials from your EMR instance metadata. To use this option, the Amazon EMR cluster must be started and your Job must be running on this cluster. For more information, see Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances. This option enables you to develop your Job without having to put any AWS keys in the Job, thus easily comply with the security policy of your organization.

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.

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.

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.

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.

Bucket

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

The bucket and the Redshift database to be used must be in the same region on Amazon. This could avoid the S3ServiceException errors known to Amazon. For further information about these errors, see S3ServiceException Errors.

Key

Type in an object key to assign to the file uploaded to Amazon S3.

Field Separator

Enter the character used to separate fields.

Text enclosure

Select the character in a pair of which the fields are enclosed.

Delete local file after putting it to s3

Select this check box to delete the local file after being uploaded to Amazon S3. By default, this check box is selected.

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.

Encoding

Select an encoding type for the data in the file to be generated.

Config client

Select this check box to configure client parameters for Amazon S3. Click the [+] button below the table displayed to add as many rows as needed, each row for a client parameter, and set the following attributes for each parameter:

• Client Parameter: Click the cell and select a parameter from the drop-down list.

• Value: Enter the value for the corresponding client parameter.

For information about S3 client parameters, go to Client Configuration.

STS Endpoint

Select this check box to specify the AWS Security Token Service (STS) endpoint from which to retrieve the session credentials. For example, enter sts.amazonaws.com.

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

Select the AWS region of the STS service. If the region is not in the list, you can enter its name between double quotation marks. The default value is us-east-1.

This drop-down list is available only when the Assume Role check box is selected.

If the administrator of the account to which the role belongs provided you with an external ID, enter its value here. The External Id is a unique identifier that allows a limited set of users to assume the role.

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

When you assume a role, the trust policy of this role might require Multi-Factor Authentication (MFA). In this case, you must indicate the identification number of the hardware or virtual MFA device that is associated with the user who assumes the role.

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

When you assume a role, the trust policy of this role might require Multi-Factor Authentication (MFA). In this case, you must indicate a token code. This token code is a time-based one-time password produced by the MFA device.

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

List session tags in the form of key-value pairs. You can then use these session tags in policies to allow or deny access to requests.

Transitive: select this check box to indicate that a tag will persist to the next role in a role chain.

For more information about tags, see Passing Session Tags in AWS STS

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

Enter the Amazon Resource Names (ARNs) of the IAM managed policies that you want to use as managed session policies. Use managed session policies to limit the permissions of the session. 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 Assume Role check box is selected.

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 Assume Role check box is selected.

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

NB_LINE: the number of rows processed. 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 more information about variables, see Using contexts and variables.

Usage rule

This component is more commonly used with the tRedshiftBulkExec component to feed Amazon Redshift with a delimited/CSV file. Used together they offer gains in performance while feeding Amazon Redshift.
