The queries to get page and revision metadata are ordered by page id, and within each page, by revision id. This is guaranteed. The behavior of rev_parent_id is not guaranteed however, in certain edge cases. See e.g. https://phabricator.wikimedia.org/T193211
Anyone who uses this field care to weigh in?

Hi,
Perhaps there is documentation about this, but I have looked for the past hour and haven’t found anything.
I was wondering if it is guaranteed that all revisions given in the enwiki-latest-pages-meta-history files are in order of parent->child->grandchild->… In a few examples, it looks like they follow this pattern. I ask because I need them in order and it would be nice if I didn’t have to do that with the <parentid> field.
Thank you, Christopher
