Room - Schema export directory is not provided to the annotation processor so we cannot export the schema

I am using Android Database Component Room

I've configured everything, but when I compile, Android Studio gives me this warning:

Schema export directory is not provided to the annotation processor so we cannot export the schema. You can either provideroom.schemaLocation annotation processor argument OR set exportSchema to false.

As I understand it is the location where DB file will be located

How can it affect my app? What is the best practice here? Should I use the default location (false value)?
