In this talk, we will discuss how we implemented the Iceberg connector in Rust, replacing the original Java-wrapped version to address performance bottlenecks in serialization and memory usage. By following the Apache Iceberg specification, we built a native Rust connector that supports Iceberg’s advanced features, such as multi-catalog compatibility and streaming updates. We’ve contributed this new version to the apache/iceberg-rust repository, and will share insights into the architectural improvements and best practices for leveraging Iceberg in streaming environments.
