Gravitino 0.9.0 focuses on advancements in AI, data governance, and security. Many of its new features are already being used in production environments. The release has attracted strong interest from users from well-known companies, with AI and security capabilities drawing attention.

In this version, the community optimized the user experience for fileset catalogs and model catalogs, making it easier for users to manage their unstructured AI data and model data.

The community added a new data lineage interface. Users can now implement a custom data lineage plugin to adapt to their own system.

For security, the community has corrected some privilege semantics and fixed authorization plugin corner cases to make the entire system more robust.

Model Catalog​

Before 0.9.0, the model catalog was immutable, which was not flexible. In the new version, users can alter models and model versions and add tags #6626 #6222.

Fileset Catalog​

Gravitino now supports multiple named storage locations within a single fileset and placeholder-based path generation.

With multiple location support, users can reference data across different file systems (HDFS, S3, GCS, local, etc.) through a unified fileset interface, each with a unique location name.

The placeholder feature allows dynamic storage path generation using the {{placeholder}} syntax, automatically replacing placeholders with corresponding fileset properties.

These enhancements significantly improves the flexibility for multi-cloud environments and complex data organization patterns while maintaining a clean abstraction layer for data assets management #6681.

GVFS (Gravitino Virtual File System)​

GVFS has been enhanced to support accessing multiple locations within filesets. Users can now select which location to use through configuration properties, environment variables, or fileset default settings.

GVFS has also been refactored with a pluggable architecture allowing custom operations and hooks. This enables users to extend functionality through operations_class and hook_class configuration options for more flexible integration with their specific infrastructure #6938.

Security​

The new version has added privileges for the data model and corrected some privilege semantics. It has also fixed some bugs with the Ranger path-based plugin #6620 #6575 #6821 #6864. All of the user-related, group-related, and role-related events are now supported for the event system #2969.

Data Lineage​

The community added a data lineage interface that follows the OpenLineage API specification. Users can implement their custom data lineage plugin to adapt to their system #6617.

Core​

The community cared about performance. Performance was improved by reducing the scope of the lock and batch reading data from storage #6744 #6560 #2870.

CLI​

Additionally, there is one more change worth mentioning. Users no longer need to rely on the alias command to use the CLI. Instead, the community provided a convenient script located at ./bin/gcli.sh so that a user can directly use the CLI client #5383.

Connector​

Both the Flink connector and the Spark connector added JDBC support #6233 #6164.

Chart​

Deploying Gravitino on Kubernetes with a fully customizable configuration #6594.

Overall​

Gravitino 0.9.0 focuses on advancements in AI, data governance, and security. We thank the Gravitino community for their continued support and valuable contributions. We can continue to innovate and build thanks to all our users' feedback. Thank you for taking the time to read this! To dive deeper into the Gravitino 0.9.0 release, explore the full documentation. Your feedback is greatly valued and helps shape the future of the Gravitino project and community.

Apache Gravitino 0.8.0 is the third major release after entering the ASF. In this release, the community provides several exciting features like model catalog, Fuse for Fileset, credential vending for Fileset, Flink Iceberg and Paimon connector, Spark Paimon connector, and security enforcement.

This release blog will briefly introduce the new significant features and improvements. Please keep reading to learn more about what the community has worked on.

Model Catalog​

Besides table and messaging metadata, Gravitino supports model metadata management in version 0.8. Gravitino allows a model to have multiple versions, and users can choose the best version. 0.8 provides basic functionality, and more features will be provided in the future, such as tagging models and better integration with machine learning workflows, to help users better manage models and extract more value from data and models.

• Support model versioning metadata #4783.

Credential vending​

Credential vending is a fundamental function in the cloud. In version 0.7, credential vending was supported for the Iceberg REST server. In version 0.8, we offer support for the Gravitino server and integrate it with Fileset. Based on Credential vending, Fileset can be used more securely and conveniently. The Gravitino server will centrally manage the security key and issue a temporary token, which is only valid for the Fileset that needs to be accessed by the request, making it more secure and eliminating the need for the user side to provide information such as AKSK.

In addition to the support for GCS and S3, version 0.8 also has built-in support for OSS and ADLS credential vending, and can support other storage in a pluggable manner.

• Support credential vending for fileset client #5677.
• Support credential vending for Gravitino #4398.
• Support Aliyun OSS credential provider #5625.
• Support ADLS credential provider #5624.

Fuse for Fileset​

With the widespread use of Fileset in AI scenarios, how to improve usability and reduce user usage costs has become a major issue. In AI scenarios, users tend to access remote data in the way of local disks. Fuse for fileset is designed based on this, enabling users to access data managed by Fileset as if they were using local disks. Currently, basic alpha functionality is provided, which allows access to S3 data managed by Fileset. In subsequent versions, metadata caching functionality and support for more storage will be provided. Fuse for fileset is developed in Rust for performance considerations, and everyone is welcome to join the development.

• Implement GVFS fuse to access Gravitino fileset in the POSIX Protocol #5504.

Lakehouse Federation​

Gravitino provides a variety of catalogs, such as Apache Hive, Apache Iceberg, Apache Hudi, and Apache Paimon, etc. How can it be better connected to the surrounding ecosystem to facilitate user use? This iteration provides Flink Paimon connector, Flink Iceberg connector, and Spark Paimon connector to access data from Paimon and Iceberg. More connectors will be supported in the future. Let's look forward to it.

• Support Iceberg catalog in Flink connector #3515.
• Support Paimon catalog in Flink connector #5194 #5193 #5192.
• Support Paimon catalog in Spark connector #5722.

Security enforcement​

As a metadata management system, security is of the utmost importance. In this iteration, we managing security policies in chain authorization, and support the push-down of SQL security policies and path-based security policies. Additionally, the privilege policies of Iceberg and Paimon tables can be pushed down to Ranger. Based on Gravitino's security policies, a solid foundation is provided for your business development.

• Chain authorization multiple underlying data source #5774.
• SQL based authorization plugin #5530.
• Add path-based authorization securable object and user-group mapping interface #5966.
• Use chain authorization to support Hive and HDFS authorization #5956.
• Ranger Authorization HDFS Plugin #5731.

Other notable enhancements​

Iceberg REST server​

• Generate credential according to the data path and metadata path #5648.
• Integrate audit log framework for Iceberg REST server #5556.
• Add schema and view event for Iceberg REST server #5438 #5437. Add HTTP header to Iceberg event #5518.

Core​

• Optimization tree lock when drop and load Table/Schema #6044.
• Support ADLS storage for Gravitino Iceberg catalog and Spark connector #5954.
• Support pre-event for Gravitino server #5317.
