--- Comment #7 from Markus markus@objectbox.io --- PS.: the math is different if you have really short keys, e.g. 4 bytes. In that case a node in the page should be around 18 bytes (?; from what I saw: 8 bytes meta info, 4 bytes key, 6 bytes page no). So let's say 225 page refs per page. Thus, going down 2 pages by one level may result in up to 450 pages or 1.8 MB. That might be too much already. Solvable by limiting the max number of pages to look for, e.g. first 100 pages.
