I read the Trevni Specificaiton:
and I can't see where the row ids are stored for each value in each column.
Am I missing something obvious? Is the spec incomplete on that point?
Also, to confirm, my understanding is columnar formats are efficient because
they store column values sorted and can thereby find specific values or
ranges of values quickly. While the spec mentions the benefits of sorting,
I don't see a requirement that column values be sorted. Can we depend that
the blocks of column values are sorted?
