# tdynamoDBOutput Standard properties These properties are used to configure tdynamoDBOutput running in the Standard Job framework. The Standard tdynamoDBOutput component belongs to the Big Data and the Databases NoSQL families. The component in this framework is available in all Talend products with Big Data and in Talend Data Fabric. ## Basic settings | Properties | Description | | --- | --- | | Property type | Either Built-In or Repository.


Built-In: No property data stored centrally.


Repository: Select the repository file where the
properties are stored. | | Access key | Enter the access
key ID that uniquely identifies an AWS Account. For further information about how to
get your Access Key and Secret Key, see [Getting Your AWS Access
Keys](http://docs.aws.amazon.com/ses/latest/DeveloperGuide/get-aws-keys.html). | | Secret key | Enter 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. | | Inherit credentials from AWS role | Select this checkbox to leverage the instance profile credentials. These
credentials can be used on Amazon EC2 instances, and are delivered through the
Amazon EC2 metadata service. To use this option, your Job must be running within
Amazon EC2 or other services that can leverage IAM Roles for access to resources.
For more information, see [Using an IAM Role to Grant Permissions to
Applications Running on Amazon EC2 Instances](http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2.html). | | 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 checkbox to assume that
role. Then specify the values for the following parameters to create a new assumed
role session. | | Region | Specify the AWS region by selecting or entering a region name between double
quotation marks (e.g. *"us-east-1"*). For more information about the
AWS Region, see [Regions and Endpoints](http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region). | | Table name | Specify the name of the table to be written. | | Schema and Edit schema | | | Action on data | On the data of the table defined, you can perform one of the following operations:

| | Create table if does not exist | Select this option to create the table if it does not already
exists. | | Primary key type | Select how to specify the primary key of the specified table. | | Partition key | Specify the partition key of the specified table. | | Sort key | Specify the sorted key of the specified table. | | Partition key type | Select the data type of the partition key. | | Sort key type | Select the data type of the sort key. | ## Advanced settings | Properties | Description | | --- | --- | | tStatCatcher Statistics | Select this checkbox to gather the Job processing metadata at the Job level
as well as at each component level. | | Signing region | 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 dropdown list is available only when the Assume role
checkbox is selected. | | Specify 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 checkbox is available only when the Assume
role checkbox is selected. | | External ID | 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 checkbox
is selected. | | Serial number | 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 checkbox
is selected. | | Token code | 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 checkbox
is selected. | | Tags | 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 checkbox 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](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html#id_session-tags_role-chaining)

This field is available only when the Assume role checkbox
is selected. | | IAM policy ARNs | 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](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)

This field is available only when the Assume role checkbox
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](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)

This field is available only when the Assume role check box
is selected. | | Use server URL | Select this check box and in the Server URL
field displayed, specify the Web service URL of the DynamoDB database service. | ## Global Variables | Variables | Description | | --- | --- | | Global Variables | NB\_LINE:
the number of rows processed. This is an After variable and it returns an integer.


QUERY: the query statement
being processed. This is a Flow variable and it returns a string.


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 checkbox is
cleared, if the component has this checkbox.

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](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/contexts-and-variables). | ## Usage | Usage guidance | Description | | --- | --- | | **Usage rule** | This component is usually used as an end component of a Job or
subJob and it always needs an input link. |
