Gravitino 0.6.0-incubating

This blog post will briefly introduce the new features and significant improvements. Keep reading to learn what the community has worked on and understand Gravitino’s use cases.

Introducing the unified RBAC model for Gravitino

Access control is a crucial feature for the enterprise use of a data catalog, providing users with unified and centralized authorization and authentication capabilities. This release introduces a role-based access control (RBAC) model in Gravitino to authorize different securable objects in a unified manner.

We use Privilege, SecurableObject, Role, User, and Group to define the permissions.

Privilege

Privilege defines the types of operations on different metadata objects, and is used to allow or deny a specific type of operation on a metadata object.

SecurableObject

SecurableObject binds multiple operation-specific types of privileges to a single metadata object.

Role

A Role is a collection of SecurableObjects, and a role represents multiple operation type permissions on multiple metadata objects.

User
Users are granted one or multiple roles, and users have different operating privileges depending on their roles.

Group

To make it easier to grant a single permission to multiple users, we can add users to a group, and then grant one or more roles to that user group. This process allows all users belonging to that user group to have the permissions in those roles.

More importantly, the privileges authorized by the user in Gravitino will be pushed down to the underlying permission system. Currently, we support push permissions to Apache Ranger, others like IAM are under development.

For more information about how our RBAC works, please check out our design document. To enable and use access control in Gravitino, please refer to the user document.

Our implementation of unified access control capability is still in the alpha stage, and we’re striving to add more features and make it stable as soon as possible, so please stay tuned.

Separation of the Iceberg REST catalog service

Apache Iceberg is a first-class citizen, and Gravitino has provided an embedded Iceberg REST catalog service since version 0.3. We have seen the increased demands and adoption of Iceberg REST catalog service as a standalone server. So, in version 0.6.0, we refactored the whole architecture and modularized the Iceberg REST catalog service as a standalone service, allowing it to be deployed with or without the Gravitino server. Besides the refactoring, we also bumped the supported version to Iceberg 1.5.2, added support for S3 cloud storage, and now support the registerTable interface.

Iceberg REST catalog support is crucial to Gravitino, and modularization is just the first step. In future releases, we will add more features like cloud storage support and integrating Gravitino’s RBAC model, credential vending, etc.

To use the Gravitino Iceberg REST catalog service, please check our user document. The umbrella issue is #4058.

Tagging support

Tagging on metadata objects is useful for data discovery, classification, and data governance. It can also be leveraged by query engines to provide tag-based access control. In Gravitino 0.6.0, we introduce tag support users can add tags on metadata objects like CATALOG, SCHEMA, TABLE, FILESET, and TOPIC. To know how our tag system is designed, please check out the design document and issue #3344. To use tags in both REST API and Java SDK, please see how to manage tags.

Apache Flink Gravitino connector

As an open data catalog, we want to be able to support all query engines. Therefore, alongside Trino and Apache Spark, we have added Apache Flink as our newest supported query engine.

In 0.6.0, we added a new Flink Gravitino connector #1354 and supported querying Hive tables using Flink with Gravitino. Hive support is just our first step, we will continue to add more table support.

To know how to use the Flink Gravitino connector, please refer to our documentation.

Apache Paimon table management in Gravitino

Apache Paimon has become quite popular this year, and many companies use Paimon to build their streaming warehouse or lakehouse. To manage all the lakehouse tables in a unified manner, Gravitino has added Paimon table management in 0.6.0 #1129. Users can use our unified API to manage Paimon tables as well as other tables. To know more about how to manage Paimon tables, please refer to Lakehouse Paimon Catalog document.

Add Python GVFS support for fileset

In Gravitino 0.5, we added a Java Hadoop Compatible Filesystem (HCFS) support (GVFS) for fileset read/write in Gravitino. The provided Java GVFS can be used by query engines like Apache Spark to read/write data from files or folders. Although this works well in big data, AI development is largely dominated by Python, which can create an obstacle and hinder users from using Fileset with AI frameworks.

In 0.6.0, we followed the Python fsspec to provide a Python GVFS package that can be used by popular Python frameworks like Apache Arrow, Pandas, Ray, LlamaIndex, and more. You can check out Python GVFS document for more information.

Notable enhancements

Gravitino core

• Support catalog reload after a property is altered #2267.
• Deprecate KV store and add H2 support as embedded storage backend #3968.

Catalog relate
