Amazon SageMaker Lakehouse (AWS Glue)

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

Requirements

The S3 Tables support is currently experimental. To use it, install the following extensions:

FORCE INSTALL aws FROM core_nightly;
FORCE INSTALL httpfs FROM core_nightly;
FORCE INSTALL iceberg FROM core_nightly;

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

Connecting to Amazon SageMaker Lakehouse

Configure your role, region, and credential provider (or explicit credentials) 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'
);

Then, connect to the catalog using the ENDPOINT_TYPE glue option:

ATTACH '⟨account_id⟩:s3tablescatalog/⟨namespace_name⟩' AS glue_catalog (
    TYPE iceberg,
    ENDPOINT_TYPE glue
);

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⟩;
