Datazone - consuming published data in an environment

Question

Hi Team,

I am doing some analysis on datazone service. I have done following successfully so far:
1- I have created a domain, projects and created datalake envs inside projects
2- I have noticed that Datazone is creating default (pub/sub) databases and roles. It is assigning necessary lakeformation access to these new databases in glue catalogue.
3- I managed to create data source and then publish from existing lakeformation governed glue catalogue table under one project in a domain
4- But during consumption , once i subscribe these tables are added under the default glue catalogue database created as part of env and only the datazone created role has access to it.
5- Now I want to do couple of things here, publish data in existing glue catalogue db and provide access to one of the existing role in AWS.

Please let me know if it is possible?

Answer

#### Publish Data in Existing Glue Catalogue Database: 
You can publish data in an existing Glue Catalogue database by specifying its name when creating an AWS Glue data source in Amazon DataZone. [Publishing data](https://docs.aws.amazon.com/datazone/latest/userguide/publishing-data.html)

#### Provide Access to an Existing AWS Role: 
Attach a policy with necessary permissions to the AWS role to access the Glue Catalogue database. The policy should include actions like `glue:GetDatabase`, `glue:GetTables`, and `glue:CreateTable`, with resources specifying the database and tables in the Glue Catalogue. [Review IAM permissions needed for the AWS Glue Studio user](https://docs.aws.amazon.com/glue/latest/dg/getting-started-min-privs.html)
