72 | daniel-mar | 67 | <p><i>A UUIDv7 measures time in the Unix Epoch with an accuracy |
68 | between 1ms and 245ns, depending on how many bits are spent for the timestamp (48-60 bits). |
||
69 | The rest of the UUID (62-74 bits) is filled with random data. |
||
70 | The timestamp is at the front of the UUID, therefore the UUIDs are monotonically increasing, |
||
75 | daniel-mar | 71 | which is good for using them in database indexes. |
72 | Since this UUID version does not contain a MAC address, it is also |
||
72 | daniel-mar | 73 | recommended due to the improved privacy.</i></p> |
