Quick question:
Looks like java iceberg does not have datafile level projection implemented (eg: I don't seem to see filtering in the filescan related to default values.)

I also try to look for design doc on this but couldn't find one, it would be great if you could share the design doc on this, thanks!

I've wrapped this up in #1644
