On this put up, we are going to present you the way Databricks on AWS common goal compute can combine with the AWS Glue Iceberg REST Catalog for metadata entry and use Lake Formation for knowledge entry. To maintain the setup on this put up simple, the Glue Iceberg REST Catalog and Databricks cluster share the identical AWS account.

Resolution overview

On this put up, we present how tables cataloged in Knowledge Catalog and saved on Amazon S3 might be consumed from Databricks compute utilizing Glue Iceberg REST Catalog with knowledge entry secured utilizing Lake Formation. We are going to present you the way the cluster might be configured to work together with Glue Iceberg REST Catalog, use a pocket book to entry the information utilizing Lake Formation short-term vended credentials, and run evaluation to derive insights.

The next determine exhibits the structure described within the previous paragraph.

Stipulations

To observe together with the answer introduced on this put up, you want the next AWS conditions:

1. Entry to the Lake Formation knowledge lake administrator in your AWS account. A Lake Formation knowledge lake administrator is an IAM principal that may register Amazon S3 areas, entry the Knowledge Catalog, grant Lake Formation permissions to different customers, and consider AWS CloudTrail See Create a knowledge lake administrator for extra info.
2. Allow full desk entry for exterior engines to entry knowledge in Lake Formation.
   • Signal into Lake Formation console as an IAM administrator and select Administration within the navigation pane.
   • Select Software integration settings and choose Permit exterior engines to entry knowledge in Amazon S3 areas with full desk entry.
   • Select Save.
     
3. An present AWS Glue database and tables. For this put up, we are going to use an AWS Glue database named icebergdemodb, which accommodates an Iceberg desk named individual and knowledge is saved in an S3 common goal bucket named icebergdemodatalake.
   
   
4. A user-defined IAM position that Lake Formation assumes when accessing the information within the above S3 location to vend scoped credentials. Comply with the directions offered in Necessities for roles used to register areas. For this put up, we are going to use the IAM position LakeFormationRegistrationRole.

Along with the AWS conditions, you want entry to Databricks Workspace (on AWS) and the power to create a cluster with No isolation shared entry mode.

Arrange an occasion profile position. For directions on find out how to create and arrange the position, see Handle occasion profiles in Databricks. Create buyer managed coverage named: dataplane-glue-lf-policy with under insurance policies and fix the identical to the occasion profile position:

                "glue:UpdateTable",
                "glue:GetDatabase",
                "glue:GetDatabases",
                "glue:GetCatalog",
                "glue:GetCatalogs",
                "glue:GetPartitions",
                "glue:GetPartition",
                "glue:GetTable",
                "glue:GetTables"
            ],
            "Useful resource": [
                "arn:aws:glue:<aws_region>:<accountid>:table/icebergdemodb/*",
                "arn:aws:glue:<aws_region>:<accountid>:database/icebergdemodb",
                "arn:aws:glue:<aws_region>:<accountid>:catalog"
            ]
        },
        {
            "Impact": "Permit",
            "Motion": [
                "lakeformation:GetDataAccess"
