What? This is definitely not the case and can’t be because B-tree nodes change while UUIDs do not.
- mixmastamyk 11mo agoI didn’t mean that literally, but no longer editable. Was supposed to have “like” etc in there.
- dpark 11mo agoBut UUIDv7 doesn’t change that at all. It doesn’t matter what flavor of UUID you choose. The ID is always “like” an index to a block in that you traverse the tree to find the node. What UUIDv7 does is improve some performance characteristics when creating new entries and potentially for caching.
