# Apache Iceberg
How to export results from Materialize to Apache Iceberg tables.
> **Public Preview:** This feature is in public preview.


Iceberg sinks provide exactly once delivery of updates from Materialize into
[Apache Iceberg](https://iceberg.apache.org/)[^1] tables hosted on either
[Amazon S3
Tables](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-tables.html)[^2]
or [Google Cloud BigLake](https://cloud.google.com/biglake)[^3]. As data
changes in Materialize, the corresponding Iceberg tables are automatically
kept up to date. You can sink data from a materialized view, a source, or a
table.

Follow the guide for the platform hosting your Iceberg tables:

- [AWS S3 Tables](/serve-results/sink/iceberg-aws/)
- [GCP BigLake](/serve-results/sink/iceberg-gcp/) <a class="private-preview-inline" href="https://materialize.com/preview-terms/">(feature in private preview)</a>
