 This guide walks you through querying Redpanda topics as Iceberg tables in https://docs.snowflake.com/en/user-guide/tables-iceberg[Snowflake^], with AWS S3 as object storage and a catalog integration using https://other-docs.snowflake.com/en/opencatalog/overview[Open Catalog^].

 * A Snowflake account.
 * An Open Catalog account. To https://other-docs.snowflake.com/en/opencatalog/create-open-catalog-account[create an Open Catalog account^], you require ORGADMIN access in Snowflake.
 * An internal catalog created in Open Catalog with your Tiered Storage AWS S3 bucket configured as external storage.

 Follow this guide to https://other-docs.snowflake.com/en/opencatalog/create-catalog#create-a-catalog-using-amazon-simple-storage-service-amazon-s3[create a catalog^] with the S3 bucket configured as external storage. You require admin permissions to carry out these steps in AWS:

---
 . If you don't already have one, create an IAM policy that gives Open Catalog read and write access to your S3 bucket.
 . Create an IAM role and attach the IAM policy to the role.
 . After creating a new catalog in Open Catalog, grant the catalog's AWS IAM user access to the S3 bucket.

-. Enable the integration for a topic by configuring the topic property `redpanda.iceberg.mode`. This mode creates an Iceberg table for the topic consisting of two columns, one for the record metadata including the key, and another binary column for the record's value. See xref:manage:iceberg/about-iceberg-topics.adoc#enable-iceberg-integration[Enable Iceberg integration] for more details on Iceberg modes. The following examples show  how to use xref:get-started:rpk-install.adoc[`rpk`] to either create a new topic, or alter the configuration for an existing topic, to set the Iceberg mode to `key_value`.
