08/30/2021, 3:45 PMNo, SST uses CF, and if the infrastructure doesn’t change, is not going to deploy anything.

08/30/2021, 3:45 PMCF checks the stack diff before deploying.

08/30/2021, 3:48 PMThe diff command shows the difference between a deployed stack and the local definition of the stack.
Adrián Mouly
08/30/2021, 3:48 PMThat way you can know if there is a diff or not.

08/30/2021, 3:48 PMThis is what SST uses to know if it has to deploy anything or not.
