The blog post just said v6 by mistake when it meant v4.hinkley 2y agoV6 is just a v4 rearranged to behave more like v7 for the purposes of b-tree insertion.dwattttt 2y agoI believe V6 is a reordering of V1, not V4. V4 is random aside from the bits specifying version & variant, ~6/7 bits.deleted 2y ago[deleted]
