Hi, Jarosław Potiuk mentioned the usage of GIT pre-commit for incremental validation checks in his talk at the Apache Conference https://aceu19.apachecon.com/session/its-breeze-develop-airflow
The general idea is to only check the files being changed and/or added for LINT testing, only executing the tests being influenced by changes (AFAIK via code flow check), but unfortunately, he mentioned the check of licenses via RAT for only the changed/added files did not succeed for him and his team. I met Philipp at the conference and he mentioned that perhaps the command line parameters of excluding all files, but including some files (those added & changed) would cover this scenario. Philipp asked me to write to the mailing list, so everyone might become aware of this interesting scenario. Also, put Jaroslaw on CC, so he might test RAT as pre-commit on Airflow with Phillipps proposed solution. Cheers, Svante PS: More information on the framework managing pre-commit hooks that Apache Airflow is using can be found at https://pre-commit.com/
