> It may require regenerating all pages, but depending on the generator that may not be particularly expensive - they may cache partial assets, so you replace part of the build asset and then the build is basically a bunch of cat-like calls, which tend to be extremely cheap. I've been thinking about this, and you can only do quick dependecy checks if the input is in files, right? So if the actual data is in a database then you do have to have some process to dump the changed data into files from the database, so the build system can pick them up. Otherwise, if the build system takes data directly from the db then it doesn't know if the data is changed, so it has to retrieve everything from database which won't be efficient.
