![]() Airflow schedules the consumer DAG after the dataset has been updated. The producer DAG has a task that creates or updates the dataset defined by a Uniform Resource Identifier (URI). The following diagram illustrates the workflow. ![]() The DAG that will be scheduled when one or more datasets are updated.This type of dependency also provides you with increased observability into the dependencies between your DAGs and datasets in the Airflow UI. You should consider using this dependency if you have two DAGs related via an irregular dataset update. You have an additional option now to create inter-DAG dependencies using datasets besides ExternalTaskSensor or TriggerDagRunOperator.You can create smaller, more self-contained DAGs, which chain together into a larger data-based workflow using datasets.Datasets may be updated by upstream producer tasks, and updates to such datasets contribute to scheduling downstream consumer DAGs.The following are some of the attributes of a dataset: An Airflow dataset is a stand-in for a logical grouping of data that can trigger a Directed Acyclic Graph (DAG) in addition to regular DAG triggering mechanisms such as cron expressions, timedelta objects, and Airflow timetables. With the release of Apache Airflow v2.4.0, Airflow introduced datasets. New feature: Data-aware scheduling using datasets In this post, we provide an overview of the features and capabilities of Apache Airflow v2.4.3 and how you can set up or upgrade your Amazon MWAA environment to accommodate Apache Airflow v2.4.3 as you orchestrate using workflows in the cloud at scale. Additionally, with Apache Airflow v2.4.3 support, Amazon MWAA has upgraded to Python v3.10.8, which supports newer Python libraries like OpenSSL 1.1.1 as well as major new features and improvements. Earlier in 2023, we added support for Apache Airflow v2.4.3 so you can enjoy the same scalability, availability, security, and ease of management with Airflow’s most recent improvements. Amazon MWAA supports multiple versions of Apache Airflow (v1.10.12, v2.0.2, and v2.2.2). Amazon Managed Workflows for Apache Airflow (Amazon MWAA) is a managed orchestration service for Apache Airflow that makes it simple to set up and operate end-to-end data pipelines in the cloud at scale.
