You can lead your plugins in open up resource and also use additional plugins structured on your necessity. ![]() Airflow provides all the necessary information of each job like as performance time, landing time, records, etc. Scalable Mainly all the data-driven businesses prefer to use Airflow, therefore the difficulty of workflow will develop as relocating ahead.
