Apache Airflow Standard Providers

This package provides "standard" operators, hooks, and sensors for Apache Airflow. It extends the core Airflow functionality with common components that were historically part of the main `apache-airflow` package before the modularization introduced in Airflow 2.0. The current version is 1.12.2, and providers are released and versioned independently from Airflow core following a Semver scheme, often with more frequent releases than Airflow itself.
