Harness Zero Copy data sharing from Salesforce Data Cloud to Amazon Redshift for Unified Analytics – Part 2

In the era of digital transformation and data-driven decision making, organizations must rapidly harness insights from their data to deliver exceptional customer experiences and gain competitive advantage. Salesforce and Amazon have collaborated to help customers unlock value from unified data and accelerate time to insights with bidirectional Zero Copy data sharing between Salesforce Data Cloud and Amazon Redshift.

In the Part 1 of this series, we discussed how to configure data sharing between Salesforce Data Cloud and customers’ AWS accounts in the same AWS Region. In this post, we discuss the architecture and implementation details of cross-Region data sharing between Salesforce Data Cloud and customers’ AWS accounts.

Solution overview

Salesforce Data Cloud provides a point-and-click experience to share data with a customer’s AWS account. On the AWS Lake Formation console, you can accept the datashare, create the resource link, mount Salesforce Data Cloud objects as data catalog views, and grant permissions to query the live and unified data in Amazon Redshift. Cross-Region data sharing between Salesforce Data Cloud and a customer’s AWS accounts is supported for two deployment scenarios: Amazon Redshift Serverless and Redshift provisioned clusters (RA3).

Cross-Region data sharing with Redshift Serverless

The following architecture diagram depicts the steps for setting up a cross-Region datashare between a Data Cloud instance in US-WEST-2 with Redshift Serverless in US-EAST-1.

Cross-Region data sharing set up consists of the following steps:

The Data Cloud admin identifies the objects to be shared and creates a Data Share in the data cloud provisioned in the US-WEST-2
The Data Cloud admin links the Data Share with the Amazon Redshift Data Share target. This creates an AWS Glue Data Catalog view and a cross-account Lake Formation resource share using the AWS Resource Access Manager (RAM) with the customer’s AWS account in US-WEST-2.
The customer’s Lake Formation admin accepts the datashare invitation in US-WEST-2 from the Lake Formation console and grants default (select and describe) permissions to an AWS Identity and Access Management (IAM) principal.
The Lake Formation admin switches to US-EAST-1 and creates a resource link pointing to the shared database in the US-WEST-2 Region.
The IAM principal can log in to the Amazon Redshift query editor in US-EAST-1 and creates an external schema referencing the datashare resource link. The data can be queried through these external tables.

Cross-Region data sharing with a Redshift provisioned cluster

Cross-Region data sharing across Salesforce Data Cloud and a Redshift provisioned cluster requires additional steps on top of the Serverless set up. Based on the Amazon Redshift Spectrum considerations, the provisioned cluster and the Amazon Simple Storage Service (Amazon S3) bucket must be in the same Region for Redshift external tables. The following architecture depicts a design pattern and steps to share data with Redshift provisioned clusters.

Steps 1–5 in the set up remain the same across Redshift Serverless and provisioned cluster cross-Region sharing. Encryption must be enabled on both Redshift Serverless and the provisioned cluster. Listed below are the additional steps:

Create a table from datashare data with the CREATE TABLE AS SELECT Create a datashare in Redshift serverless and grant access to the Redshift provisioned cluster.
Create a database in the Redshift provisioned cluster and grant access to the target IAM principals. The datashare is ready for query.

The new table needs to be refreshed periodically to get the latest data from the shared Data Cloud objects with this solution.

Considerations when using data sharing in Amazon Redshift

For a comprehensive list of considerations and limitations of data sharing, refer to Considerations when using data sharing in Amazon Redshift. Some of the important ones for Zero Copy data sharing includes:

Data sharing is supported for all provisioned RA3 instance types (ra3.16xlarge, ra3.4xlarge, and ra3.xlplus) and Redshift Serverless. It isn’t supported for clusters with DC and DS node types.
For cross-account and cross-Region data sharing, both the producer and consumer clusters and serverless namespaces must be encrypted. However, they don’t need to share the same encryption key.
Data Catalog multi-engine views are generally available in commercial Regions where Lake Formation, the Data Catalog, Amazon Redshift, and Amazon Athena are available.
Cross-Region sharing is available in all LakeFormation supported regions.

Prerequisites

The prerequisites remain the same across same-Region and cross-Region data sharing, which are required before proceeding with the setup.

Configure cross-Region data sharing

The steps to create a datashare, create a datashare target, link the datashare target to the datashare, and accept the datashare in Lake Formation remain the same across same-Region and cross-Region data sharing. Refer to Part 1 of this series to complete the setup.

Cross-Region data sharing with Redshift Serverless

If you’re using Redshift Serverless, complete the following steps:

On the Lake Formation console, choose Databases in the navigation pane.
Choose Create database.
Under Database details¸ select Resource link.
For Resource link name, enter a name for the resource link.
For Shared database’s region, choose the Data Catalog view source Region.
The Shared database and Shared database’s owner ID fields are populated manually from the database metadata.
Choose Create to complete the setup.

The resource link appears on the Databases page on the Lake Formation console, as shown in the following screenshot.

Launch Redshift Query Editor v2 for the Redshift Serverless workspace The cross-region data share tables are auto-mounted and appear under awsdatacatalog. To query, run the following command and create an external schema. Specify the resource link as the Data Catalog database, the Redshift Serverless Region, and the AWS account ID.
```
CREATE external SCHEMA cross_region_data_share --<<SCHEMA_NAME>>
FROM DATA CATALOG DATABASE 'cross-region-data-share' --<<RESOURCE_LINK_NAME>>
REGION 'us-east-1' --<TARGET_REGION>
IAM_ROLE 'SESSION' CATALOG_ID '<<aws_account_id>>'; --<<REDSHIFT AWS ACCOUNT ID>>
```
Refresh the schemas to view the external schema created in the dev database
Run the show tables command to check the shared objects under the external database:
```
SHOW TABLES FROM SCHEMA dev.cross_region_data_share --<<schema name>>
```

Query the datashare as shown in the following screenshot.

SELECT * FROM dev.cross_region_data_share.churn_modellingcsv_tableaus3_dlm; --<<change schema name & table name>>

Cross-Region data sharing with Redshift provisioned cluster

This section is a continuation of the previous section with additional steps needed for data sharing to work when the consumer is a provisioned Redshift cluster. Refer to Sharing data in Amazon Redshift and Sharing datashares for a deeper understanding of concepts and the implementation steps.

Create a new schema and table in the Redshift Serverless in the consumer Region:

CREATE SCHEMA customer360_data_share;
CREATE TABLE customer360_data_share. customer_churn as
SELECT * from dev.cross_region_data_share.churn_modellingcsv_tableaus3__dlm;

Get the namespace for the Redshift Serverless (producer) and Redshift provisioned cluster (consumer) by running the following query in each cluster:

Create a datashare in the Redshift Serverless (producer) and grant usage to the Redshift provisioned cluster (consumer). Set the datashare, schema, and table names to the appropriate values, and set the namespace to the consumer namespace.

CREATE DATASHARE customer360_redshift_data_share;
ALTER DATASHARE customer360_redshift_data_share ADD SCHEMA customer360_data_share;
ALTER DATASHARE customer360_redshift_data_share ADD TABLE customer360_data_share.customer_churn; 
GRANT USAGE ON DATASHARE customer360_redshift_data_share 
TO NAMESPACE '5709a006-6ac3-4a0c-a609-d740640d3080'; --<<Data Share Consumer Namespace>>

Log in as a superuser in the Redshift provisioned cluster, create a database from the datashare, and grant permissions. Refer to managing permissions for Amazon Redshift datashare for detailed guidance.

The datashare is now ready for query.

You can periodically refresh the table you created to get the latest data from the data cloud based on your business requirement.
