Azure Update Report: Azure Databricks Runtime 10.4 LTS End of Life Announcement
Background and Purpose of the Update:
Azure Databricks Runtime 10.4 LTS is a long-term support (LTS) version of the Databricks-managed runtime environment available on Azure Databricks. This update announces the lifecycle milestones for this runtime: end of support occurred on March 18, 2025, and end of life will occur on November 1, 2026. The purpose of this update is to inform users and IT professionals about the deprecation timeline, enabling them to plan migration strategies and avoid disruption to their workloads.
Specific Features and Detailed Changes:
Azure Databricks Runtime 10.4 LTS provided stability, compatibility, and extended support for enterprise workloads requiring a consistent runtime environment. After November 1, 2026, this runtime version will no longer be available for use in Azure Databricks. No new clusters can be created with this runtime, and existing clusters will not be able to restart or run jobs using this version. Users must upgrade to newer supported Databricks Runtime versions to continue leveraging Databricks features and security updates.
Technical Mechanisms and Implementation Methods:
The deprecation process follows Azure Databricks’ standard lifecycle management for runtime versions. End of support means no further bug fixes, security patches, or technical assistance will be provided for Databricks Runtime 10.4 LTS. End of life marks the complete removal of the runtime from the platform, enforced at the service level, preventing cluster creation or job execution with this version. Migration to newer runtime versions typically involves updating cluster configurations, testing compatibility of notebooks, libraries, and job workflows, and validating performance and functionality in the upgraded environment.
Use Cases and Application Scenarios:
Databricks Runtime 10.4 LTS has been widely used for production workloads requiring stability and long-term support, such as enterprise data engineering pipelines, machine learning model training, and batch analytics. Organizations with compliance or regulatory requirements often select LTS versions to minimize change frequency. With this update, IT professionals must assess their current workloads running on 10.4 LTS and plan migration to newer runtime versions to maintain operational continuity and leverage ongoing improvements.
Important Considerations and Limitations:
After November 1, 2026, Databricks Runtime 10.4 LTS will be completely unavailable. Any clusters or jobs dependent on this runtime will fail to start or execute. It is critical to review all dependencies, including custom libraries, integrations, and notebook code, for compatibility with newer runtime versions. Migration may require additional testing to ensure that performance, functionality, and security requirements are met. Users should also be aware of potential changes in APIs, Spark versions, and library support in newer runtimes.
Integration with Related Azure Services:
Azure Databricks Runtime versions are tightly integrated with Azure services such as Azure Data Lake Storage, Azure Synapse Analytics, Azure Machine Learning, and Azure Key Vault. Migrating to newer Databricks Runtime versions ensures continued compatibility and support for these integrations. IT professionals should verify that their data pipelines, authentication mechanisms, and service connections remain functional after upgrading the runtime.
Summary Sentence:
Azure Databricks Runtime 10.4 LTS will reach end of life on November 1, 2026, after which it will no longer be available; IT professionals should plan to migrate workloads to newer supported runtime versions to ensure continued operation and support within Azure Databricks.
