Even in a distributed database you want increasing (even if not monotonic) keys since the underlying b-tree or whatever will very likely behave badly for entirely random data.

UUIDv7 is very useful for these scenarios since

A: A hash or modulus of the key will be practically random due to the lower bits being random or pseudo-random (ie distributes well between nodes)

B: the first bits are sortable.. thus the underlying storage on each node won't go bananas.
