In my introductory post I showed you how could subscribe to data products and then download the data sets into an Amazon Simple Storage Service (Amazon S3) bucket. I then suggested various options for further processing, including AWS Lambda functions, a AWS Glue crawler, or an Amazon Athena query.
Today we are making it even easier for you to find, subscribe to, and use third-party data with the introduction of AWS Data Exchange for Amazon Redshift. As a subscriber, you can directly use data from providers without any further processing, and no need for an Extract Transform Load (ETL) process. Because you don’t have to do any processing, the data is always current and can be used directly in your Amazon Redshift queries. AWS Data Exchange for Amazon Redshift takes care of managing all entitlements and payments for you, with all charges billed to your AWS account.
As a provider, you now have a new way to license your data and make it available to your customers.
As I was writing this post, it was cool to realize just how many existing aspects of Redshift, and Data Exchange played central roles. Because Redshift has a clean separation of storage and compute, along with built-in data sharing features, the data provider allocates and pays for storage, and the data subscriber does the same for compute. The provider does not need to scale their cluster in proportion to the size of their subscriber base, and can focus on acquiring and providing data.
Let’s take a look at this feature from two vantage points: subscribing to a data product, and publishing a data product.
AWS Data Exchange for Amazon Redshift – Subscribing to a Data Product
As a data subscriber I can browse through the AWS Data Exchange catalog and find data products that are relevant to my business, and subscribe to them.
Data providers can also create private offers and extend them to me for access via the AWS Data Exchange Console. I click My product offers, and review the offers that have been extended to me. I click on Continue to subscribe to proceed:
Then I complete my subscription by reviewing the offer and the subscription terms, noting the data sets that I will get, and clicking Subscribe:
Once the subscription is completed, I am notified and can move forward:
From the Redshift Console, I click Datashares, select Subscriptions, and I can see the subscribed data set:
Next, I associate it with one or more of my Redshift clusters by creating a database that points to the subscribed datashare, and use the tables, views, and stored procedures to power my Redshift queries and my applications.
AWS Data Exchange for Amazon Redshift – Publishing a Data Product
As a data provider I can include Redshift tables, views, schemas and user-defined functions in my AWS Data Exchange product. To keep things simple, I’ll create a product that includes just one Redshift table.
I use the spiffy new Redshift Query Editor V2 to create a table that maps US area codes to a city and a state:
Then I examine the list of existing datashares for my Redshift cluster, and click Create datashare to make a new one:
Next, I go through the usual process for creating a datashare. I select AWS Data Exchange datashare, assign a name (area_code_reference), pick the database within the cluster, and make the datashare accessible to publicly accessible clusters:
Then I scroll down and click Add to move forward:
I choose my schema (public), opt to include only tables and views in my datashare, and then add the area_codes table:
At this point I can click Add to wrap up, or Add and repeat to make a more complex product that contains additional objects.
I confirm that the datashare contains the table, and click Create datashare to move forward:
Now I am ready to start publishing my data! I visit the AWS Data Exchange Console, expand the navigation on the left, and click Owned data sets:
I review the Data set creation steps, and click Create data set to proceed:
I select Amazon Redshift datashare, give my data set a name (United States Area Codes), enter a description, and click Create data set to proceed:
I create a revision called v1:
I select my datashare and click Add datashare(s):
Then I finalize the revision:
I showed you how to create a datashare and a dataset, and to publish a product using the console. If you are publishing multiple products and/or making regular revisions, you can automate all of these steps using the AWS Command Line Interface (CLI) and the Amazon Data Exchange APIs.
