Goal

Support multiple cluster configurations (default, large, gpu) that pipelines can reference via Pipeline.cluster_profile.

Scope

  • Add [databricks.clusters] to stack.toml with named profiles
  • Generator emits one job_cluster per referenced profile
  • Each task gets job_cluster_key from its pipeline cluster_profile

Acceptance

  • Pipelines with cluster_profile=large get a different cluster spec
  • Unused profiles are not emitted
  • Default profile works for all existing pipelines
