## TL;DR

Asset-aware orchestration lets agents reason about data products and dependencies instead of only cron times and task names.

## Core Explanation

Traditional workflow orchestration asks whether a task ran. Asset-oriented orchestration asks whether a data asset was produced, updated, partitioned, or consumed. That shift is useful for agents because it links operational state to business-relevant data objects.

Event-driven schedules can reduce stale data by triggering work when upstream assets change. Agents still need guardrails: event deduplication, partition awareness, freshness targets, and a way to tell backfills from normal incremental runs.

## Source-Mapped Facts

- Apache Airflow documentation describes asset-aware scheduling as scheduling DAGs based on updates to assets. ([source](https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/assets.html))
- Dagster documentation describes software-defined assets as objects in persistent storage that capture data dependencies. ([source](https://docs.dagster.io/guides/build/assets))
- Prefect documentation describes assets as tracked entities that flows can create, read, or update. ([source](https://docs.prefect.io/v3/concepts/assets))
