Pipeline name used as the identifier in the catalog.
PIPELINE my_pipelineThe PIPELINE keyword followed by an identifier declares a new pipeline and registers it in the catalog under the given name. The name may be a simple identifier such as `daily_etl` or a dot-qualified name like `workspace.daily_etl` to scope the pipeline to a specific workspace. This clause is the only required element of a PIPELINE declaration; all other clauses are optional and may follow in any order. The name serves as the unique `entity_ref` for the pipeline and is used to reference it throughout the system, including in schedule bindings, execution logs, and the GUI catalog tree.
