Expand data access through Apache Iceberg using Delta Lake UniForm on AWS
The landscape of big data management has been transformed by the rising popularity of open table formats such as Apache Iceberg, Apache Hudi, and Linux Foundation Delta Lake. These formats, designed to address the limitations of traditional data storage systems, have become essential in modern data architectures. As organizations adopt various open table formats to suit their specific needs, the demand for interoperability between these formats has grown significantly. This interoperability is crucial for enabling seamless data access, reducing data silos, and fostering a more flexible and efficient data ecosystem.
Delta Lake UniForm is an open table format extension designed to provide a universal data representation that can be efficiently read by different processing engines. It aims to bridge the gap between various data formats and processing systems, offering a standardized approach to data storage and retrieval. With UniForm, you can read Delta Lake tables as Apache Iceberg tables. This expands data access to broader options of analytics engines.
This post explores how to start using Delta Lake UniForm on Amazon Web Services (AWS). You can learn how to query Delta Lake native tables through UniForm from different data warehouses or engines such as Amazon Redshift as an example of expanding data access to more engines.
How Delta Lake UniForm works
UniForm allows other table format clients such as Apache Iceberg to access Delta Lake tables. Under the hood, UniForm generates Iceberg metadata files (including metadata and manifest files) that are required for Iceberg clients to access the underlying data files in Delta Lake tables. Both Delta Lake and Iceberg metadata files reference the same data files. UniForm generates multiple table format metadata without duplicating the actual data files. When an Iceberg client reads a UniForm table, it first accesses the Iceberg metadata files for the UniForm table, which then allows the Iceberg client to read the underlying data files.
There are two options to use UniForm:
- Create a new Delta Lake table with UniForm
- Enable UniForm on your existing Delta Lake table
First, to create a new Delta Lake table enabling UniForm, you configure table properties for UniForm in a CREATE TABLE
DDL query. The table properties are 'delta.universalFormat.enabledFormats'='iceberg'
and 'delta.enableIcebergCompatV2'='true'
. When these options are set to the CREATE TABLE
query, Iceberg metadata files are generated along with Delta Lake metadata files. In addition to these options, Delta Lake table protocol versions that define supported features by the table such as delta.minReaderVersion
and delta.minWriterVersion
are required to be set to 2
and 7
or more respectively. For more information about the table protocol versions, refer to What is a table protocol specification? in Delta Lake public document. Appendix 1. Create a new Delta Lake table with UniForm shows an example query to create a new Delta Lake UniForm table.
You can also enable UniForm on an existing Delta Lake table. This option is suitable if you have Delta Lake tables in your environment. Enabling UniForm doesn’t affect your current operations on the Delta Lake tables. To enable UniForm on a Delta Lake table, run REORG TABLE db.existing_delta_lake_table APPLY (UPGRADE UNIFORM(ICEBERG_COMPAT_VERSION=2))
. After running this query, Delta Lake automatically generates Iceberg metadata files for the Iceberg client. In the example in this post, you run this option and enable UniForm after you create a Delta Lake table.
For the information about enabling UniForm, refer to Enable Delta Lake UniForm in the Delta Lake public document. Note that the extra package (delta-iceberg
) is required to create a UniForm table in AWS Glue Data Catalog. The extra package is also required to generate Iceberg metadata along with Delta Lake metadata for the UniForm table.
Example use case
A fictional company built a data lake with Delta Lake on Amazon Simple Storage Service (Amazon S3) that’s mainly used through Amazon Athena. According to its usage expansion, this company wants to expand data access to cloud-based data warehouses such as Amazon Redshift for flexible analytics use cases.
There are a few challenges to achieve this requirement. Delta Lake isn’t natively supported in Amazon Redshift. For those data warehouses, Delta Lake tables need to be converted to manifest tables, which requires additional operational overhead. You need to run the GENERATE
command on Spark or use a crawler in AWS Glue to generate manifest tables, and you need to sync those manifest tables every time the Delta tables are updated.
Delta Lake UniForm can be a solution to meet this requirement. With Delta Lake UniForm, you can make the Delta Table compatible with the other open table formats such as Apache Iceberg, which is natively supported in Amazon Redshift. Users can query those Delta Lake tables as Iceberg tables through UniForm.
The following diagram describes the architectural overview to achieve that requirement.
In this tutorial, you create a Delta Lake table with a synthetic review dataset that includes different products and customer reviews and enable UniForm on that Delta Lake table to make it accessible from Amazon Redshift. Each component works as follows in this scenario:
- Amazon EMR (Amazon EMR on EC2 cluster with Apache Spark): An Apache Spark application on an Amazon EMR cluster creates a Delta Lake table and enables UniForm on it. Only Delta Lake client can write to the Delta Lake UniForm table, making Amazon EMR act as a writer.
- Amazon Redshift: Amazon Redshift uses Iceberg clients to read records from the Delta Lake UniForm table. It’s limited to reading records from the table and cannot write to it.
- Amazon S3 and AWS Glue Data Catalog: These are used to manage the underlying files and the catalog of the Delta Lake UniForm table. The data and metadata files for the table are stored in an S3 bucket. The table is registered in AWS Glue Data Catalog.

Appendix 1: Create a new Delta Lake table with UniForm
You can create a Delta Lake table with UniForm enabled using the following DDL.
Appendix 2: Run queries from Snowflake against the UniForm table
Delta Lake UniForm also allows you to run queries on a Delta Lake table from Snowflake. In this section, you run the same analytic query on the UniForm table using Snowflake as you previously did using Amazon Redshift Serverless in Run queries from Amazon Redshift against the UniForm table. Then you confirm that the query results from Snowflake match the results obtained from the Amazon Redshift Serverless query.
Configure IAM roles for Snowflake to access AWS Glue Data Catalog and Amazon S3
To query the Delta Lake UniForm table in Data Catalog from Snowflake, the following configurations are required.
- IAM roles: Create IAM roles for Snowflake to access Data Catalog and Amazon S3.
- Data Catalog integration with Snowflake: Snowflake provides two catalog options for Iceberg tables such as Using Snowflake as the Iceberg catalog and Using an external catalog such as Data Catalog. In this post, you choose AWS Glue Data Catalog as an external catalog. For information about the catalog options, refer to Iceberg catalog options in the Snowflake public documentation.
- An external volume creation for Amazon S3: To access the UniForm table from Snowflake, an external volume for Amazon S3 needs to be configured. With this configuration, Snowflake can connect the S3 bucket that you created for Iceberg tables. For information about the external volume, refer to Configure an external volume for Iceberg tables.
Create IAM roles for Snowflake to access AWS Glue Data Catalog and Amazon S3
Create the following two IAM roles for Snowflake to access AWS Glue Data Catalog and Amazon S3.
- SnowflakeIcebergGlueCatalogRole: This IAM role is used for Snowflake to access the Delta Lake UniForm table in AWS Glue Data Catalog.
- SnowflakeIcebergS3Role: This IAM role is used for Snowflake to access the table’s underlying data in the S3 bucket.
To configure the IAM roles, complete the following steps:
- Choose Launch stack:
- Enter
snowflake-iceberg
as the stack name and choose Next. - Select I acknowledge that AWS CloudFormation might create IAM resources with custom names.
- Choose Submit.
- After the stack creation is complete, check the CloudFormation Outputs tab. Make a note of the names and ARNs of the two IAM roles, which are used in the following section.
Create an AWS Glue Data Catalog Integration
Create a catalog integration for AWS Glue Data Catalog. For more information about the catalog integration for AWS Glue Data Catalog, refer to Configure a catalog integration for AWS Glue in the Snowflake public documentation. To configure the catalog integration, complete the following steps:
- Access your Snowflake account and open an empty worksheet (query editor).
- Run the following query and create a catalog integration with AWS Glue Data Catalog. Replace
<YOUR_ACCOUNT_ID>
with the IAM role ARN from thesnowflake-iceberg
CloudFormation Ouputs tab, and replace<REGION>
with the region of AWS Glue Data Catalog.
- Retrieve
GLUE_AWS_IAM_USER_ARN
andGLUE_AWS_EXTERNAL_ID
by usingDESCRIBE CATALOG INTEGRATION glue_catalog_integration
in the editor. The output is similar to the following:
- Update the IAM role you created using the CloudFormation stack to enable Snowflake to access AWS Glue Data Catalog using that IAM role. Open Trust Relationships of SnowflakeIcebergGlueCatalogRole on the IAM console, choose Edit and update the trust relationship using the following policy. Replace
<GLUE_AWS_IAM_USER_ARN>
and<GLUE_AWS_EXTERNAL_ID>
with the names you obtained in the previous step.
You completed setting up the IAM role for Snowflake to access your Data Catalog resources. Next, configure the IAM role for Amazon S3 access.
Register Amazon S3 as an external volume
In this section, you configure an external volume for Amazon S3. Snowflake accesses the UniForm table data files in S3 through the external volume. For the configuration of an external volume for S3, refer to Configure an external volume for Amazon S3 in Snowflake public documentation. To configure the external volume, complete the following steps:
- In the query editor, run the following query to create an external volume for the Delta Lake S3 bucket. Replace
<DeltaLakeS3Bucket>
with the name of the S3 bucket that you created in Launch a CloudFormation template to configure basic resources from the CloudFormation Outputs tab. Replace<ACCOUNT_ID>
with your AWS account ID.
- Retrieve
STORAGE_AWS_IAM_USER_ARN
andSTORAGE_AWS_EXTERNAL_ID
by runningDESCRIBE EXTERNAL VOLUME delta_lake_uniform_s3
in the editor. The output is similar to the following:
- Update the IAM role you created using the CloudFormation template (in Create IAM roles for Snowflake to access AWS Glue Data Catalog and Amazon S3) to enable Snowflake to use this IAM role. Open Trust Relationships of SnowflakeIcebergS3Role on the IAM console, choose Edit, and update the trust relationship with the following policy. Replace
<STORAGE_AWS_IAM_USER_ARN>
and<STORAGE_AWS_EXTERNAL_ID>
with the values from the previous step.
The next step is to create an Iceberg table to run queries from Snowflake.
Create an Iceberg table in Snowflake
In this section, you create an Iceberg table in Snowflake. The table is an entry point for Snowflake to access the Delta Lake UniForm table in AWS Glue Data Catalog. To create the table, complete the following steps:
- (Optional) If you don’t have a database in Snowflake, run
CREATE DATABASE <DATABASE_NAME>
, replacing<DATABASE_NAME>
with a unique database name for the Iceberg table. - Run the following query in the Snowflake query editor. In this case, the database
delta_uniform_snow_db
is chosen for the table. Configure the following parameters:EXTERNAL_VOLUME
: created byCREATE OR REPLACE EXTERNAL VOLUME
query in the previous section, such asdelta_lake_uniform_s3
.CATALOG
: created by theCREATE CATALOG INTEGRATION
query in the previous section, such asglue_catalog_integration
.CATALOG_TABLE_NAME
: the name of Delta Lake UniForm table you created in Data Catalog such ascustomer_reviews
.
The complete query is below:
After the table creation is complete, you’re ready to query the UniForm table in AWS Glue Data Catalog from Snowflake.
Query the UniForm table from Snowflake
In this step, you query the UniForm table from Snowflake. Paste and run the following analytic query in the Snowflake query editor.
The query result shows the same output as you saw in Review the added records in Delta Lake UniForm table from Amazon Redshift Serverless section.
Now you can query from Snowflake against the Delta Lake table by enabling Delta Lake UniForm.
