Breaking Changes

Version 0.14.0

To accommodate using Databricks Free Edition, we had to change the structure of overrides defined in conf/<env>/databricks.yml.

Before:

default:
    environments:
        - environment_key: default
    spec:
        environment_version: '4'
        dependencies:
            - ../dist/*.whl
    tasks:
        - task_key: default
          environment_key: default

After:

resources:
    jobs:
        default:
            environments:
                - environment_key: default
            spec:
                environment_version: '4'
                dependencies:
                    - ../dist/*.whl
            tasks:
                - task_key: default
                environment_key: default

This was done so that we could default to creating a volume in a newly initialized kedro-databricks project.

While this requires users to migrate their databricks configuration, it also extends the ability of kedro-databricks beyond that of applying overrides to specific jobs. Now, you can add any type of resource in your conf/<env>/databricks.yml and those will be generated as well.

NOTE: Merges are only applied for jobs currently, so any other defined will be generated as defined in the configuration.

In addition to the changes to the structure of conf/<env>/databricks.yml, we now also tag the generated resources with their resource type and target environment, meaning that newly generated resources will be named like target.<env>.<resource-type>.<resouce-name>.yml.
