Iceberg-Rust : Efficient Data Management In Rust With Apache Iceberg™

Apache Iceberg™ Rust is a native Rust implementation of the Apache Iceberg table format, designed for managing large-scale datasets in data lake environments.

It provides a highly scalable and efficient solution for accessing and manipulating Iceberg tables directly in Rust-based applications.

Components Of Iceberg-Rust

The project comprises several modular components, each serving a distinct purpose:

• iceberg: Core library for interacting with Iceberg tables.
• iceberg-datafusion: Integration with DataFusion, enabling query execution.
• iceberg-catalog-glue: AWS Glue catalog support.
• iceberg-catalog-hms: Hive Metastore catalog integration.
• iceberg-catalog-memory: In-memory catalog for lightweight use cases.
• iceberg-catalog-rest: REST-based catalog for distributed environments.

Key Features

1. Rust Compatibility: Built and tested with stable Rust (minimum supported version 1.77.1). Unstable Rust is used for development tools like clippy and rustfmt, ensuring downstream users are unaffected.
2. Layered Architecture:
   • FileIO Abstraction: Powered by Apache OpenDAL, supporting storage backends like Amazon S3, Azure Blob, Google Cloud Storage, and local file systems.
   • Data Format Support: Integration with formats such as Parquet and Avro.
   • High-Level APIs: Includes table readers/writers and support for SQL-like operations.
3. Extensibility:
   • Future plans include WebAssembly bindings for browser-based table access and C bindings for integration with tools like DuckDB1.

Iceberg-Rust is an open-source project under the Apache Software Foundation (ASF). Contributions are encouraged through:

• Submitting issues or feature requests.
• Participating in discussions via mailing lists or Slack (#rust channel).
• Following the Contributing Guide23.

Several prominent projects leverage Iceberg-Rust:

• Databend: A cloud-native data warehouse integrating Iceberg tables.
• Lakekeeper: REST catalog with data access controls.
• RisingWave: Real-time event streaming database.
