Pros
- • Software-defined assets model fits modern data platforms naturally
- • Type-checked I/O and strong testing story catch errors before production
- • Polished UI (Dagit) with lineage, run history, and asset observability
Cons
- • Heavier conceptual model than Prefect — assets, ops, jobs, resources
- • Operational footprint is larger to self-host than lightweight schedulers
- • Smaller connector ecosystem than Airflow's operator catalog
