Schedule name used as the identifier.
SCHEDULE daily_etlThe SCHEDULE keyword followed by a name opens a schedule declaration and assigns it a unique identifier within the pipeline. The name follows standard SQL identifier rules and is used to reference this schedule in logs, the control plane UI, and notification payloads. Each pipeline may contain multiple SCHEDULE declarations, but every name must be unique within the pipeline scope. This clause is required and must appear as the first token after the SCHEDULE keyword, before any other schedule clauses.
