Amazon S3 has introduced sort and z-order compaction for Apache Iceberg tables, enhancing query performance and reducing costs. Sort compaction organizes data files by user-defined column orders, minimizing the number of files accessed. Z-order compaction facilitates file pruning during queries across multiple columns. These innovations are crucial for high-ingest datasets that generate numerous small files affecting performance. Automatic hierarchical sorting and configuration options through AWS Glue Data Catalog optimize the management of these tables, further enhancing querying efficiency.
Sorting and z-order compaction significantly reduce scan sizes and cost. Sort compaction organizes files by user-defined order, enhancing query efficiency for specific column access.
Using z-order compaction allows for effective file pruning when queries involve multiple columns, leading to improved read performance and reduced operational costs.
Managed compaction automatically organizes files in S3 Tables, significantly optimizes query performance through hierarchical sorting based on metadata.
The introduction of sort and z-order compaction extends the advantages of compaction in Iceberg tables, providing essential tools for handling high-ingest datasets.
