Glue

Certified

Important Capabilities​

CapabilityStatusNotes
Detect Deleted Entities✅Enabled by default when stateful ingestion is turned on.
Domains✅Supported via the domain config field
Platform Instance✅Enabled by default
Table-Level Lineage✅Enabled by default

Note: if you also have files in S3 that you'd like to ingest, we recommend you use Glue's built-in data catalog. See here for a quick guide on how to set up a crawler on Glue and ingest the outputs with DataHub.

This plugin extracts the following:

  • Tables in the Glue catalog
  • Column types associated with each table
  • Table metadata, such as owner, description and parameters
  • Jobs and their component transformations, data sources, and data sinks

IAM permissions​

For ingesting datasets, the following IAM permissions are required:

{
    "Effect": "Allow",
    "Action": [
        "glue:GetDatabases",
        "glue:GetTables"
    ],
    "Resource": [
        "arn:aws:glue:$region-id:$account-id:catalog",
        "arn:aws:glue:$region-id:$account-id:database/*",
        "arn:aws:glue:$region-id:$account-id:table/*"
    ]
}

For ingesting jobs (extract_transforms: True), the following additional permissions are required:

{
    "Effect": "Allow",
    "Action": [
        "glue:GetDataflowGraph",
        "glue:GetJobs",
    ],
    "Resource": "*"
}

plus s3:GetObject for the job script locations.

CLI based Ingestion​

Install the Plugin​

pip install 'acryl-datahub[glue]'

Starter Recipe​

Check out the following recipe to get started with ingestion! See below for full configuration options.

For general pointers on writing and running a recipe, see our main recipe guide.

source:
  type: glue
  config:
    # Coordinates
    aws_region: "my-aws-region"

sink:
  # sink configs

Compatibility​

To capture lineage across Glue jobs and databases, a requirements must be met – otherwise the AWS API is unable to report any lineage. The job must be created in Glue Studio with the "Generate classic script" option turned on (this option can be accessed in the "Script" tab). Any custom scripts that do not have the proper annotations will not have reported lineage.
