Snowflake Iceberg Table

A Snowflake table that stores data and metadata in the Apache Iceberg format in customer-managed cloud storage, using Snowflake or an external catalog.

Definition

Iceberg tables give near-native Snowflake performance while letting other engines read the same data. With Snowflake as the catalog, tables are fully read-write. With an external catalog such as AWS Glue or a REST catalog, Snowflake can now also write, depending on catalog support. Snowflake Open Catalog is a managed Apache Polaris service.

Exam tip

Iceberg tables keep data in your storage through an external volume, unlike standard tables, which Snowflake stores and manages.
