Connect to an AWS Glue Data Catalog as a catalog provider for federated SQL query.

Configuration

from

The from field is used to specify the catalog provider. For Glue, you need only specify glue. The catalog is unique for each AWS account and AWS region.

name

The name field is used to specify the name of the catalog in Spice. Tables from the AWS Glue Data Catalog will be available in the schema with this name in Spice. The schema hierarchy of the external catalog is preserved in Spice.

include

Use the include field to specify which tables to include from the catalog. The include field supports glob patterns to match multiple tables. For example, *.my_table_name would include all tables with the name my_table_name in the catalog from any schema. Multiple include patterns are OR'ed together and can be specified to include multiple tables.

params

The following parameters are supported for configuring the connection to the Glue Data Catalog:

Parameter Name	Definition
glue_region	The AWS region for the Glue Data Catalog. E.g. us-west-2.
glue_key	Access key (e.g. AWS_ACCESS_KEY_ID for AWS). If not provided, credentials will be loaded from environment variables or IAM roles.
glue_secret	Secret key (e.g. AWS_SECRET_ACCESS_KEY for AWS). If not provided, credentials will be loaded from environment variables or IAM roles.
glue_session_token	Session token (e.g. AWS_SESSION_TOKEN for AWS) for temporary credentials

Authentication

If AWS credentials are not explicitly provided in the configuration, the connector will automatically load credentials from the following sources in order. These credentials will be used to connect to the S3 bucket as well as the Glue catalog.

1. Environment Variables:

   • AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
   • AWS_SESSION_TOKEN (if using temporary credentials)

2. Shared AWS Config/Credentials Files:

   • Config file: ~/.aws/config (Linux/Mac) or %UserProfile%\.aws\config (Windows)

   • Credentials file: ~/.aws/credentials (Linux/Mac) or %UserProfile%\.aws\credentials (Windows)

   • The AWS_PROFILE environment variable can be used to specify a named profile, otherwise the [default] profile is used.

   • Supports both static credentials and SSO sessions

   • Example credentials file:

   :::tip To set up SSO authentication:

   1. Run aws configure sso to configure a new SSO profile
   2. Use the profile by setting AWS_PROFILE=sso-profile
   3. Run aws sso login --profile sso-profile to start a new SSO session :::

3. AWS STS Web Identity Token Credentials:

   • Used primarily with OpenID Connect (OIDC) and OAuth

The connector will try each source in order until valid credentials are found. If no valid credentials are found, an authentication error will be returned.

:::note[IAM Permissions] Regardless of the credential source, the IAM role or user must have appropriate S3/Glue permissions (e.g., s3:ListBucket, glue:GetTable) to access the tables. If the Spicepod connects to multiple different AWS services, the permissions should cover all of them. :::

Required IAM Permissions

The IAM role or user needs the following permissions to access Iceberg tables in S3/Glue:

Permission Details

Permission	Purpose
s3:ListBucket	Required. Allows scanning all objects from the bucket
s3:GetObject	Required. Allows fetching objects
glue:GetCatalog	Required. Retrieve metadata about the specified catalog.
glue:GetDatabases	Required. List the databases available in the current catalog.
glue:GetDatabase	Required. Retrieve metadata about the specified database.
glue:GetTable	Required. Retrieve metadata about the specified table.
glue:GetTables	Required. List the tables available in the current database.

Limitations

:::warning

• This catalog connector is limited to tables that use the S3 data source. Kinesis and Kafka data sources are not currently supported.
• This catalog connector is currently limited to Iceberg tables, tables with parquet or CSV data format only.

There is a cookbook recipe to configure an AWS Glue Data Connector in Spice.
