Intelligent Data Organization, Automatically
Iceberg Clustering intelligently optimizes the data layout in an Apache Iceberg lakehouse by automatically organizing data files for faster queries, compacting small files, and optimizing metadata to enhance performance and storage efficiency.
Performance in the AI Era
Challenge
The Limitations of Traditional Partitioning
Traditional partitioning techniques require careful planning and ongoing maintenance to avoid performance issues, data silos, and query slowdowns. Manual partitioning demands significant engineering effort, creates operational overhead, and often leads to inefficiencies as data volumes grow and access patterns evolve.
Enter Iceberg Clustering.
Solution
Intelligent Data Organization, Automatically
Iceberg Clustering intelligently optimizes your data layout by automatically reorganizing data within partitions, sorting files for faster queries, and compacting small files—all without requiring manual intervention. As part of Dremio's Intelligent Data Lakehouse Platform, Iceberg Clustering ensures optimal query performance while maintaining flexibility and fault tolerance.
benefits
Effortless Optimization. Superior Performance. Lower Costs.
Iceberg Clustering eliminates the manual effort of data layout optimization, dramatically reducing query times and compute costs.
- Effortless Table Organization: No manual partitioning required—just specify columns and let table maintenance ensure optimal clustering
- Enhanced Fault Tolerance: Dynamically adapts to data changes without human errors or constant adjustments
- Improved Performance: Achieve 30% faster queries (compared to traditional partitioning strategies) while reducing engineering overhead to focus on insights rather than maintenance
CAPABILITIES
How Iceberg Clustering Works
Iceberg Clustering works natively with Apache Iceberg and seamlessly integrates with Dremio's table maintenance commands for simple, effective data organization.
- Intelligent Data Layout: Automatically organizes data within a single directory structure, removing the impact of partition skew or over-partitioning
- Optimized File Sorting: Arranges data within files to maximize query performance based on column clustering definitions
- Native Maintenance Integration: Works seamlessly with Iceberg maintenance commands like VACUUM and OPTIMIZE
- Open Standard Implementation: Built on Apache Iceberg, ensuring compatibility and preventing vendor lock-in
