+title: Apache Gravitino 1.2.0
+slug: gravitino-1-2-0-release-notes
+authors: [Hui Yu]
+tags: [apache,gravitino,metadata,multicloud,model,security,government]
+---
+
+Apache Gravitino 1.2.0 has been released\! This release introduces major new
capabilities including a new Table Maintenance Service (TMS), a new ClickHouse
catalog, end-to-end UDF management, authorization for Iceberg view operation, a
redesigned Web UI, and broad improvements across connectors, authorization, and
clients.
+
+**Release Date:** 2026-03-13 **Previous Version:** 1.1.0 (2025-12-16)
+
+## Highlights
+
+- **Table Maintenance Service (TMS) foundational framework** — Data platforms
can now shift from reactive firefighting to proactive table health. Gravitino
analyzes your tables and automatically schedules the right maintenance
operations, at the right times.
+- **ClickHouse catalog** — Teams running real-time analytics on ClickHouse can
now govern it alongside their lakehouse, with one metadata layer for both
streaming and batch workloads.
+- **Scan planning offload** — Query engines like DuckDB and Spark can now
offload scan planning to Gravitino's IRC server, reducing query latency and
client-side complexity — making Gravitino a more capable catalog server for the
growing Iceberg ecosystem.
+- **Ecosystem reach** — Multi-version Trino connector (435–478), Flink user
authentication, and multi-cluster fileset support and Web UI v2 broaden
Gravitino's integration surface across the modern data stack.
+
+---
+
+## New Features
+
+1. **Table Maintenance Service (TMS)**
[\#9546](https://github.com/apache/gravitino/issues/9546),
[\#9652](https://github.com/apache/gravitino/issues/9652),
[\#9653](https://github.com/apache/gravitino/issues/9653),
[\#9654](https://github.com/apache/gravitino/issues/9654),
[\#9983](https://github.com/apache/gravitino/issues/9983),
[\#9984](https://github.com/apache/gravitino/issues/9984),
[\#9985](https://github.com/apache/gravitino/issues/9985),
[\#9986](https://github.com/apache/gravi [...]
+
+ Maintaining a healthy lakehouse table requires ongoing maintenance work —
compaction, rewriting data files, and expiring snapshot cleanup. Gravitino
1.2.0 introduces the Table Maintenance Service (TMS), which analyzes table
statistics and automatically schedules the right maintenance operations at the
right time. This allows data platforms to move from reactive firefighting to
proactive table health management.
+
+2. **ClickHouse Catalog**
[\#9738](https://github.com/apache/gravitino/issues/9738),
[\#9754](https://github.com/apache/gravitino/issues/9754),
[\#9755](https://github.com/apache/gravitino/issues/9755),
[\#9756](https://github.com/apache/gravitino/issues/9756),
[\#9820](https://github.com/apache/gravitino/issues/9820),
[\#9865](https://github.com/apache/gravitino/issues/9865)
+
+ ClickHouse is widely adopted for large-scale real-time analytics. Gravitino
1.2.0 introduces a full-featured ClickHouse catalog with full DDL support
including distributed and partitioned cluster modes.
+
+3. **User-Defined Function (UDF) Management**
[\#9525](https://github.com/apache/gravitino/issues/9525),
[\#9527](https://github.com/apache/gravitino/issues/9527),
[\#9528](https://github.com/apache/gravitino/issues/9528),
[\#9529](https://github.com/apache/gravitino/issues/9529),
[\#9530](https://github.com/apache/gravitino/issues/9530),
[\#9531](https://github.com/apache/gravitino/issues/9531),
[\#9532](https://github.com/apache/gravitino/issues/9532),
[\#9561](https://github.com/apach [...]
+
+ Teams can now centrally register, update, and govern UDFs, and Spark can
automatically discover and invoke these functions through Gravitino's catalog
interface. Gravitino 1.2.0 introduces end-to-end UDF management: Java API,
server-side REST interface, relational storage backend, Java client support,
Spark FunctionCatalog integration, Python client, Web UI management for visual
browsing/creation, and complete documentation with OpenAPI specifications.
+
+4. **Iceberg REST Catalog: Support scan planning cache**
[\#9048](https://github.com/apache/gravitino/issues/9048)
+
+ Adding a cache for scan planning improves performance by caching the
results of the scan planning phase, which determines which data files need to
be read for a query. Since scan planning involves reading and parsing Iceberg
metadata and manifest files, caching avoids repeating this expensive work for
similar queries. As a result, it reduces metadata I/O, lowers query latency,
and decreases load on object storage and the planning service.
+
+5. **Authorization support for Iceberg REST catalog view operations**
[\#9744](https://github.com/apache/gravitino/issues/9744),
[\#9745](https://github.com/apache/gravitino/issues/9745),
[\#9746](https://github.com/apache/gravitino/issues/9746),
[\#9747](https://github.com/apache/gravitino/issues/9747),
[\#9915](https://github.com/apache/gravitino/issues/9915)
+
+ Views are an important abstraction for data access control but have long
been a governance blind spot. Gravitino 1.2.0 manages Iceberg views as
first-class entities, introducing view management, generic storage, view-level
permissions, and full authorization support for IRC view operations. This
enables teams to govern views alongside tables and apply fine-grained access
control policies to view access while maintaining consistent enforcement of
underlying table permissions.
+
+6. **Generic Lakehouse Catalog: Delta Lake External Table Support**
[\#9647](https://github.com/apache/gravitino/issues/9647)
+
+ Delta Lake is one of the most widely deployed open table formats. Gravitino
now supports registering and managing external Delta tables through the generic
lakehouse catalog, enabling unified governance for Delta alongside Iceberg,
Hudi, and other formats without data migration. This allows organizations to
manage Delta Lake workloads through an open catalog architecture, reducing
dependence on proprietary catalog services such as Unity Catalog.
+
+7. **Trino Connector Multi-version Support**
[\#9718](https://github.com/apache/gravitino/issues/9718),
[\#9719](https://github.com/apache/gravitino/issues/9719),
[\#9894](https://github.com/apache/gravitino/issues/9894),
[\#9952](https://github.com/apache/gravitino/issues/9952),
[\#9961](https://github.com/apache/gravitino/issues/9961),
[\#9964](https://github.com/apache/gravitino/issues/9964),
[\#10091](https://github.com/apache/gravitino/issues/10091)
+
+ Gravitino now supports Trino versions 435 through 478, with a connector
architecture designed to maintain compatibility with future Trino releases.
+
+8. **Multi-cluster Fileset Support**
[\#9568](https://github.com/apache/gravitino/issues/9568),
[\#9312](https://github.com/apache/gravitino/issues/9312)
+ Production data platforms often span multiple storage clusters. Through
GVFS multi-cluster filesets, Gravitino now allows a single fileset to reference
storage locations across different clusters.
+
+9. **Flink Connector: User Authentication**
[\#9564](https://github.com/apache/gravitino/issues/9564)
+ The Gravitino Flink connector now supports user authentication, enabling
secure access to Gravitino-managed metadata from Flink jobs.
+
+10. **Web UI v2 Reconstruction**
[\#9758](https://github.com/apache/gravitino/issues/9758)
+ The Gravitino Web UI now supports managing ClickHouse catalogs and UDFs,
along with improved views for tags, policies, and task templates. The updated
interface provides a more streamlined experience for navigating governance
resources. Web v1 remains available during the transition period.
