:::warning Warning ::: :::info This is an early-access feature and might change in incompatible ways in future Airflow versions. However this feature can be considered bug-free, and Airbnb has been using this feature in Production since early 2020 and has significantly reduced their costs for heavy use of sensors. :::
The smart sensor is a service (run by a builtin DAG) which greatly reduces airflow’s infrastructure cost by consolidating some of the airflow long running light weight tasks.
