Airflow 2.0 introduces a reimagined KubernetesExecutor that enhances performance and flexibility compared to its predecessor in version 1.10, providing users with more robust control over task execution in Kubernetes environments. The new features, such as the pod_template_file, executor_config, and pod_mutation_hook, allow users and admins to utilize the full extent of the Kubernetes API, offering ease in configuring pods with specific needs like node affinities, resource allocations, and environmental variables. This level of customization affords data engineers the ability to manage tasks with greater precision without the complexity of creating Docker images for each task. The simplified architecture reduces errors and confusion, while the CeleryKubernetesExecutor allows users to optimize task execution by combining benefits from both Celery and Kubernetes executors. Migration tools for new and existing users, along with available YAML templates, facilitate a smoother transition to this updated system, promising speed improvements and a streamlined user experience.
