Sortable (timestamp-first) unique identifier
Why?
Random identifiers can be bad for performance when inserting into balanced b-tree indexes.
Variants
| variant | timestamp bits | random bits |
|---|---|---|
u32, i32 |
16 (hours since unix epoch) | 16 |
u64, i64 |
40 (seconds since unix epoch) | 24 |
u128, i128 |
64 (milliseconds since unix epoch) | 64 |
