Amazon SageMaker Lakehouse (AWS Glue)

Support for Amazon SageMaker Lakehouse (AWS Glue) is currently experimental.

The iceberg extension supports reading Iceberg tables through the Amazon SageMaker Lakehouse (a.k.a. AWS Glue) catalog.

Requirements

To use it, install the following extensions:

INSTALL aws;
INSTALL httpfs;
INSTALL iceberg;

If you want to switch back to using extensions from the core repository, follow the extension documentation.

Connecting to Amazon SageMaker Lakehouse (AWS Glue)

Create an S3 secret using the Secrets Manager:

CREATE SECRET (
    TYPE s3,
    PROVIDER credential_chain,
    CHAIN sts,
    ASSUME_ROLE_ARN 'arn:aws:iam::account_id:role/role',
    REGION 'us-east-2'
);

In this example we use an STS token, but other authentication methods are supported.

Then, connect to the catalog:

ATTACH 'account_id' AS glue_catalog (
    TYPE iceberg,
    ENDPOINT 'glue.REGION.amazonaws.com/iceberg',
    AUTHORIZATION_TYPE 'sigv4'
);

Or alternatively:

ATTACH 'account_id' AS glue_catalog (
    TYPE iceberg,
    ENDPOINT_TYPE 'glue'
);

Warning As with Amazon S3 Tables, ENDPOINT_TYPE glue always builds an endpoint of the form glue.⟨region⟩.amazonaws.com/iceberg, which is incorrect for regions that do not use the plain amazonaws.com suffix (most notably the AWS China regions cn-north-1 and cn-northwest-1, which use amazonaws.com.cn). For such regions, attach with an explicit ENDPOINT (with the correct host) together with AUTHORIZATION_TYPE 'sigv4' instead of using ENDPOINT_TYPE.

The warehouse identifier (the first argument to ATTACH) accepts the following forms:

Warehouse Meaning
: The default catalog of the caller's account.
⟨account_id⟩ A 12-digit AWS account ID.
⟨account_id⟩:⟨catalog⟩ A named catalog in the given account.
⟨catalog⟩/⟨sub_catalog⟩ A nested (federated) catalog.
⟨account_id⟩:⟨catalog⟩/⟨sub_catalog⟩ A nested catalog in the given account.

To check whether the attachment worked, list all tables:

SHOW ALL TABLES;

You can query a table as follows:

SELECT count(*)
FROM glue_catalog.namespace_name.table_name;

If you have an S3 Tables federated catalog, you can create a table using the standard CREATE TABLE syntax;

CREATE TABLE glue_catalog.namespace_name.table_name (a INTEGER, b VARCHAR);

If the catalog is not federated by S3 Tables, you may need to create pass a location table property. You can do so using the WITH clause.

CREATE TABLE glue_catalog.namespace_name.table_name (a INTEGER, b VARCHAR)
WITH (
    'location' = 's3://path/to/location'
);

You can learn more about the WITH clause at Table Properties.
