Impala Performance on Iceberg Tables - Optimizations and Benchmarks

Explore the performance of Apache Impala on Iceberg tables in this 27-minute conference talk from The ASF. Dive into the implementation details of Impala's optimized C++ approach for reading Iceberg tables, contrasting it with other engines that rely on the Iceberg library. Discover how Impala efficiently handles delete files in Iceberg tables, implementing new Iceberg-specific operators for improved query performance. Gain insights into Impala's architecture, Iceberg's structure, and the performance enhancements specifically designed for Iceberg integration. Compare Impala's performance against other open-source query engines through detailed measurements. By the end, acquire a high-level understanding of both Impala and Iceberg architectures, along with Impala's competitive edge in querying Iceberg tables with position delete files.

Let’s see how fast Impala runs on Iceberg
