Databricks support lifecycles
As part of Azure Databricks's commitment to innovation, platform and runtime features might be retired and replaced by new features. Databricks Runtime releases are also retired and replaced on a regular schedule. The following tables list retirement phases and details about corresponding support for platform features and Databricks Runtime releases.
For information about previews and release types, see Azure Databricks preview releases.
Platform feature lifecycle
Azure Databricks platform feature retirement phases are described in the following table:
| Phase | Description | Support | Migration notes |
|---|---|---|---|
| Legacy | The feature is still available, but there is a newer, better feature or way to accomplish the tasks that this feature provides. This label is indicative of a future retirement date. | Full. Support and documentation are available. | Migration to a new replacement feature or a new way of accomplishing the task is encouraged, but not immediately necessary. |
| Deprecated | The feature is no longer in active development. Updates are no longer being released. The feature will soon be retired, so you need to develop a plan to stop using the feature and transition to an alternative. | Full. The feature is no longer being updated, but support and documentation are still available. | Migration to a new replacement feature or a new way of accomplishing the task is highly encouraged, because important updates are no longer being applied. |
| End of Support (EoS) | The feature is no longer in active development and support is officially unavailable. | None. Documentation might still exist, but it has been archived and is no longer being maintained. | Migration to a new replacement feature or a new way of accomplishing the task is urgent, because important updates are no longer being applied and support for issues that might arise is no longer available. |
| End of Life (EoL) | The feature has been completely removed from the Databricks product. | None | Migration to a new replacement feature or a new way of accomplishing the task is required, because the feature is no longer usable. At this point it might be very difficult to migrate. |
Databricks Runtime support lifecycles
The following tables describe the stages of support and support policies for Databricks Runtime versions. Azure Databricks releases runtimes as Beta and GA versions. Azure Databricks supports GA versions for six months, unless the runtime version is a long-term support (LTS) version. For information on supported Databricks Runtime versions, see Databricks Runtime release notes versions and compatibility.
Workloads on unsupported Databricks Runtime versions might continue to run, but Azure Databricks does not provide support or fixes.
