Knowledge-driven organizations deal with knowledge as an asset and use it throughout completely different traces of enterprise (LOBs) to drive well timed insights and higher enterprise selections. Many organizations have a distributed instruments and infrastructure throughout numerous enterprise items. This results in having knowledge throughout many cases of information warehouses and knowledge lakes utilizing a trendy knowledge structure in separate AWS accounts.
Amazon Redshift knowledge sharing lets you securely share reside, transactionally constant knowledge in a single Amazon Redshift knowledge warehouse with one other Redshift knowledge warehouse inside the similar AWS account, throughout accounts, and throughout Areas, while not having to repeat or transfer knowledge from one cluster to a different. Prospects need to have the ability to handle their permissions in a central place throughout all of their property. Beforehand, the administration of Redshift datashares was restricted to solely inside Amazon Redshift, which made it troublesome to handle your knowledge lake permissions and Amazon Redshift permissions in a single place. For instance, you needed to navigate to a person account to view and handle entry info for Amazon Redshift and the information lake on Amazon Easy Storage Service (Amazon S3). As a corporation grows, directors need a mechanism to successfully and centrally handle knowledge sharing throughout knowledge lakes and knowledge warehouses for governance and auditing, and to implement fine-grained entry management.
We just lately introduced the mixing of Amazon Redshift knowledge sharing with AWS Lake Formation. With this characteristic, Amazon Redshift prospects can now handle sharing, apply entry insurance policies centrally, and successfully scale the permission utilizing LF-Tags.
Lake Formation has been a well-liked selection for centrally governing knowledge lakes backed by Amazon S3. Now, with Lake Formation help for Amazon Redshift knowledge sharing, it opens up new design patterns and broadens governance and safety posture throughout knowledge warehouses. With this integration, you should utilize Lake Formation to outline fine-grained entry management on tables and views being shared with Amazon Redshift knowledge sharing for federated AWS Id and Entry Administration (IAM) customers and IAM roles. Lake Formation additionally offers tag-based entry management (TBAC), which can be utilized to simplify and scale governance of information catalog objects resembling databases and tables.
On this submit, we focus on this new characteristic and how one can implement TBAC to your knowledge lake and Amazon Redshift knowledge sharing on Lake Formation.
Answer overview
Lake Formation tag-based entry management (LF-TBAC) lets you group related AWS Glue Knowledge Catalog sources collectively and outline the grant or revoke permissions coverage through the use of an LF-Tag expression. LF-Tags are hierarchical in that when a database is tagged with an LF-Tag, all tables in that database inherit the tag, and when a LF-Tag is utilized to a desk, all of the columns inside that desk inherit the tag. Inherited tags then may be overridden if wanted. You then can create entry insurance policies inside Lake Formation utilizing LF-Tag expressions to grant principals entry to tagged sources utilizing an LF-Tag expression. See Managing LF-Tags for metadata entry management for extra particulars.
To reveal LF-TBAC with central knowledge entry governance functionality, we use the situation the place two separate enterprise items personal specific datasets and have to share knowledge throughout groups.
We now have a buyer care staff who manages and owns the client info database together with buyer demographics knowledge. And have a advertising and marketing staff who owns a buyer leads dataset, which incorporates info on potential prospects and speak to leads.
To have the ability to run efficient campaigns, the advertising and marketing staff wants entry to the client knowledge. On this submit, we reveal the method of sharing this knowledge that’s saved within the knowledge warehouse and giving the advertising and marketing staff entry. Moreover, there are personally identifiable info (PII) columns inside the buyer dataset that ought to solely be accessed by a subset of energy customers on a need-to-know foundation. This manner, knowledge analysts inside advertising and marketing can solely see non-PII columns to have the ability to run nameless buyer phase evaluation, however a gaggle of energy customers can entry PII columns (for instance, buyer e-mail tackle) to have the ability to run campaigns or surveys for particular teams of shoppers.
The next diagram reveals the construction of the datasets that we work with on this submit and a tagging technique to offer fine-grained column-level entry.
Past our tagging technique on the information sources, the next desk offers an outline of how we should always grant permissions to our two personas by way of tags.
IAM Position | Persona | Useful resource Kind | Permission | LF-Tag expression |
marketing-analyst | An information analyst within the advertising and marketing staff | DB | describe | (division:advertising and marketing OR division:buyer) AND classification:non-public |
. | Desk | choose | (division:advertising and marketing OR division:buyer) AND classification:non-public | |
. | . | . | . | . |
marketing-poweruser | A privileged person within the advertising and marketing staff | DB | describe | (division:advertising and marketing OR division:buyer) AND classification: non-public |
. | Desk (Column) | choose | (division:advertising and marketing OR division:buyer) AND (classification:non-public OR classification:pii-sensitive) |
The next diagram offers a high-level overview of the setup that we deploy on this submit.
The next is a high-level overview of how one can use Lake Formation to manage datashare permissions:
Producer Setup:
- Within the producers AWS account, the Amazon Redshift administrator that owns the client database creates a Redshift datashare on the producer cluster and grants utilization to the AWS Glue Knowledge Catalog in the identical account.
- The producer cluster administrator authorizes the Lake Formation account to entry the datashare.
- In Lake Formation, the Lake Formation administrator discovers and registers the datashares. They have to uncover the AWS Glue ARNs they’ve entry to and affiliate the datashares with an AWS Glue Knowledge Catalog ARN. In case you’re utilizing the AWS Command Line Interface (AWS CLI), you may uncover and settle for datashares with the Redshift CLI operations describe-data-shares and associate-data-share-consumer. To register a datashare, use the Lake Formation CLI operation register-resource.
- The Lake Formation administrator creates a federated database within the AWS Glue Knowledge Catalog; assigns tags to the databases, tables, and columns; and configures Lake Formation permissions to manage person entry to things inside the datashare. For extra details about federated databases in AWS Glue, see Managing permissions for knowledge in an Amazon Redshift datashare.
Shopper Setup:
- On the patron facet (advertising and marketing), the Amazon Redshift administrator discovers the AWS Glue database ARNs they’ve entry to, creates an exterior database within the Redshift client cluster utilizing an AWS Glue database ARN, and grants utilization to database customers authenticated with IAM credentials to start out querying the Redshift database.
- Database customers can use the views
SVV_EXTERNAL_TABLES
andSVV_EXTERNAL_COLUMNS
to search out all of the tables or columns inside the AWS Glue database that they’ve entry to; then they’ll question the AWS Glue database’s tables.
When the producer cluster administrator decides to not share the information with the patron cluster, the producer cluster administrator can revoke utilization, deauthorize, or delete the datashare from Amazon Redshift. The related permissions and objects in Lake Formation are usually not mechanically deleted.
Stipulations:
To comply with the steps on this submit, it’s essential to fulfill the next conditions:

customer_db_shared
is created.
Now the information lake administrator can view and grant entry on each the database and tables to the information client staff (advertising and marketing) personas utilizing Lake Formation TBAC.
Assign Lake Formation tags to sources
Earlier than we grant acceptable entry to the IAM principals of the information analyst and energy person inside the advertising and marketing staff, we now have to assign LF-tags to tables and columns of the customer_db_shared
database. We then grant these principals permission to acceptable LF-tags.
To assign LF-tags, comply with these steps:
- Assign the division and classification LF-tag to
customer_db_shared
(Redshift datashare) primarily based on the tagging technique desk within the resolution overview. You possibly can run the next actions on the console, however for this submit, we use the next AWS CLI command:
If the command is profitable, it’s best to get a response like the next:
- Assign the suitable division and classification LF-tag to
marketing_db
(on the S3 knowledge lake):
Be aware that though you solely assign the division and classification tag on the database stage, it will get inherited by the tables and columns inside that database.
- Assign the classification
pii-sensitive
LF-tag to PII columns of thebuyer
desk to override the inherited worth from the database stage:
Grant permission primarily based on LF-tag affiliation
Run the next two AWS CLI instructions to permit the advertising and marketing knowledge analyst entry to the client desk excluding the pii-sensitive
(PII) columns. Substitute the worth for DataLakePrincipalIdentifier
with the MarketingAnalystRoleARN
