Learn how to add an external queue to stream data between Reltio and external systems in the Tenant Management application.

1. Open the External queues page:
   1. In the Reltio Console, select Tenant Management.
   2. On the left navigation pane in the Manage section, select External queues.
2. At the top of the displayed External queues - destination configuration page, select Add configuration.

   

3. In the Service Provider field, select the appropriate message streaming service from your cloud provider:

   Option	Description
   Amazon SNS/SQS	One of: Amazon Simple Queue Service (SQS) Amazon Simple Notification Service (SNS)
   Google Pub/Sub	Google Cloud Publisher/Subscriber
   Microsoft Azure	Microsoft Azure Service Bus

   Note: The fields in the Add configuration page cascade, so some values are displayed only when a particular checkbox is selected or cleared. Some of the following field values depend on the value that you select in this Service Provider field. We've indicated these with AWS, GCP, or Azure in the Option column of the following steps. You know the drill – an asterisk (*) means a required field.
4. Specify the authentication method for your cloud provider:

   Option	Description
   Authenticate using roleAWS	Select this checkbox to authenticate using an AWS Identity and Access Management (IAM) role: Role: The AWS IAM user role. External ID: The AWS account external ID. Note: Enter the External IDs in Universally Unique Identifiers (UUID) format. Using an AWS IAM Role is a more secure way to provide access to files in an S3 bucket and it’s the preferred approach. Example of a UUID: 07515ab2-f3f0-4ac2-a7cf-3fe58e3b2b4d. For more information, see Universally unique identifier. For more information on configuring IAM roles for event streaming, see topic Configuring IAM roles for event streaming. Clear this checkbox to authenticate using AWS account key credentials: Key*: The AWS key ID. Secret*: The AWS secret access key. Note: Encode special characters in the AWS Key to enable Reltio to parse the URI. For more information, see the Encodings table in topic Message Streaming Provider. For more information on these authentication options, see the AWS documentation on Identity and Access Management and Account and Access Keys.
   Queue nameGCP	Specify the name of your queue. The name must start with a letter, but it can't start with the string goog. It can include a combination of alphanumeric characters and the special characters hyphen (-), percent (%), period (.), plus sign (+), tilde (~), and underscore (_).
   TypeAzure	Select one of the following: Queue: for point-to-point communications. Topic: For publisher or subscriber.

5. 
   
6. Provide connection details for your cloud provider:

   Option	Description
   Use ARNAWS	Specify the following: Select this checkbox to provide queue details using the Amazon Resource Name (ARN) of your AWS queue in the following format: arn:partition:service:region:account-id:resource-id Clear this checkbox to enter specific queue details: Queue name*: The name of the queue. The name can include a combination of alphanumeric characters and the special characters hyphen (-) and underscore (_). It can’t contain a period (.) since that character isn't valid in SNS/SQS. Type*: The type of AWS queue, one of SQS or SNS. Region*: The AWS region for the queue.
   GCP	Specify one of: Upload Service Account Key File: Upload your Google Developer service account key file in JSON format. Generate this in the Google Developer Console. Enter project details: Project ID*: Enter the project ID for the queue. Private key*: Enter the private key, without the first and last extra lines or any new line breaks. Client email*: Enter the email address for the client.
   Azure	Specify the following: Queue/Topic name: The name of the queue or topic. The name can be up to 260 characters and must start and end with a letter or a number. It can contain letters, numbers, and the special characters hyphen (-), period (.), slash (/), and underscore (_). Namespace name*: The name of the Azure namespace. The namespace must be between 6 and 50 characters. It must start with a letter and end with a letter or a number. It can contain only letters, numbers, and the special character hyphen (-). Authorization policy rule name*: The name of the Azure Service Bus authorization policy rule. Access key*: The key that defines the Azure Service Bus authorization policy rule primary or secondary key.

7. In the Format field, specify the Relation message format for streaming messages into a queue:

   Option	Description
   JSON	Select this to use a standard JSON file. This is the default.
   JSON_ZIP_BASE64	Select this to use a GZIP file in Base64 encoding containing a long JSON string. This format is useful for long messages whose size prevents them from being sent in standard JSON format. For more information on size limits, see the FAQs below.

   

8. In the Object filter field, optionally specify a Relation object filter expression for a message event object to be sent to this external queue. This filter query parameter uses the same expression structure as the Search and Export filters:

   filter=({Condition Type}[AND/OR {Condition Type}]*)

   

   For more information, see topic Search and Create and run an export job.

9. In the Type filter field, specify any Relation event type collections you want to stream using this external queue. By default, all event types are streamed; clear any event types you want to have ignored during transmission to the external queue. You can select CRUD events and MATCH events. For more information, see topics CRUD events and Match events.
10. Select the Transmit OV only checkbox to include only the operational values in the queue destination. By default, this checkbox is not selected and it is available for all providers and payload types. For more information, see topic Message streaming.
11. In the Payload type field, specify the payload type for messages to be streamed to this queue, one of:

    Option	Description
    Snapshot (All fields)	Stream all the fields of the objects that have changed due to the event that is being transmitted. The queue adds the object Version and the commit Time fields to the message meta data. You can use these fields to order events during data consumption. This is the default payload type.
    Snapshot (Selected fields)	Stream selected/limited fields of the objects that have changed due to the event that is being transmitted. In the displayed Event payload field, specify the attributes you want to stream. Note: You can only select simple attributes in this field. Nested and reference attributes aren’t supported as of now. For more information on attribute types, see topic Reltio attribute types. You can select the following fields: Uri type created By createdTime objectVersion commitTime CAUTION: If you clear these fields, you'll get an error message, and you won't be able to save the queue details. The queue adds the objectVersion and commitTime field to the message metadata. It adds the remaining attributes to the payload. From the dropdown list, select any additional attributes that you want to stream. Use the Search field to locate a known attribute.
    Delta	Stream only the changed fields of the objects that have changed due to the event that is being transmitted in a format similar to the Activity Log.

12. Enable streaming: Specify whether or not to publish events to this queue:
    • Select this checkbox to publish events. This is the default value.
    • Clear this checkbox not to publish events. This is useful if you aren’t ready to start streaming yet, or if you want to turn off streaming temporarily.

    

13. Select Save.
    Your external queue is ready to stream data between Reltio and external systems.
