O que é Fluxo de Trabalho?
Apache Airflow é uma plataforma de gerenciamento de fluxo de trabalho de código aberto gerenciamento de fluxo de trabalho platform created by Airbnb and later donated to the Apache Software Foundation. It is designed to allow users to programmatically author, schedule, and monitor complex workflows. Airflow helps manage data pipelines in a way that is both scalable and flexible.
Recursos principais
- Grafos Acíclicos Dirigidos (DAGs): Airflow uses DAGs to represent workflows. A DAG is a collection of tasks organized in a way that defines their dependencies and execution order. This structure allows users to visualize the flow of data and tasks.
- Geração Dinâmica de Pipelines: Workflows can be defined in Python, enabling dynamic generation of tasks based on external conditions or configurations.
- Agendador: Airflow includes a powerful scheduler that automatically triggers tasks based on time ou eventos externos, garantindo que os fluxos de trabalho sejam executados conforme o planejado.
- Interface do Usuário: It features a web-based user interface for monitoring and managing tasks. Users can view task statuses, logs, and desempenho específicas.
- Extensibilidade: Airflow supports numerous plugins and integrations with various data sources, enabling users to easily connect with tools como AWS, Google Cloud e outras.
