This is an update to #5665. There was discussion on that PR about how to project the partition tuple to the correct final type, and this PR implements the update by passing the desired data file type into
StructDataFile. I think this is the cleanest way to fix the problem.Because
StructDataFiledoes not implementStructLikeand is instead passed into aManifestWriterthat uses theDataFileAPI, the projection can't happen inwriteManifest. InsideStructDataFile, only the partition tuple's type can differ, so only that field needs to be projected.
