Hi, great post!

I am trying to dynamically change in the targets section the variables defined in the databricks.yml file. Eg:

# databricks.yml
variables:
  catalog: 
    description: The Unity Catalog catalog to use.
    default: my_catalog
  schema:
    description: The Unity Catalog schema basename to use as a prefix for all created schemas. bundle.target will be appended to this value.
    default: my_schema
  landing_data_volume:
    description: The volume to use for landing data.
    default: /Volumes/my_catalog/my_schema/landing_data

my ultimate goal is to use these variables in the targets section, in order to append a suffix such as "dev" to the schema to be deployed in the dev environment. However, a syntax like this:

# databricks.yml

targets:
  dev:
    mode: development
    variables:
      catalog: ${workspace.current_user.short_name}
      schema: ${var.schema}
    default: true
    workspace:
      host: https://my_host.cloud.databricks.com

Error: cycle detected in field resolution: variables.schema.default -> var.schema -> var.schema

which way would you recommend to sort this out?

Many thanks,

Domenico
