Apache Iceberg Materialization Enhancements in Estuary
Estuary's Apache Iceberg materialization has been updated with new features that improve flexibility and integration options. These enhancements include support for running merge queries using Amazon EMR and expanded catalog compatibility with Apache Polaris and Snowflake Open Catalog.
Feature Updates
1. Bring Your Own EMR for Merge Queries
Estuary allows users to execute MERGE INTO operations using their Amazon EMR (Elastic MapReduce) clusters. This update provides:
- The ability to control compute costs by managing EMR cluster usage.
- Integration with existing AWS-managed environments.
- Performance improvements for large-scale updates and deletes in Iceberg tables.
For configuration details, refer to the documentation.
2. Expanded Catalog Support: Apache Polaris & Snowflake Open Catalog
Estuary Flow now supports materializing Iceberg tables into Apache Polaris and Snowflake Open Catalog:
- Apache Polaris: A managed Iceberg service that simplifies Iceberg adoption and table management.
- Snowflake Open Catalog: Enables the use of Iceberg tables stored in S3, GCS, or Azure Blob Storage while integrating with Snowflake’s query engine and governance features.
For implementation details, visit the documentation.
