Readme

uuid6

New time-based UUID formats which are suited for use as a database key.

This module extends immutable UUID objects (the UUID class) with the functions uuid6(), uuid7(), and uuid8() from the proposed IETF RFC 9562.

Install

pip install uuid6

Usage

import uuid6

my_uuid = uuid6.uuid6()
print(my_uuid)
assert my_uuid &lt; uuid6.uuid6()

my_uuid = uuid6.uuid7()
print(my_uuid)
assert my_uuid &lt; uuid6.uuid7()

my_uuid = uuid6.uuid8()
print(my_uuid)
assert my_uuid &lt; uuid6.uuid8()

import uuid

my_uuid = uuid.UUID(hex="C232AB00-9414-11EC-B3C8-9E6BDECED846")
assert uuid6.uuid1_to_uuid6(my_uuid) == uuid.UUID(hex="1EC9414C-232A-6B00-B3C8-9E6BDECED846")

Which UUID version should I use?

> Implementations SHOULD utilize UUID version 7 over UUID version 1 and 6 if possible.

UUID version 7 features a time-ordered value field derived from the widely implemented and well known Unix Epoch timestamp source, the number of milliseconds since midnight 1 Jan 1970 UTC, leap seconds excluded. As well as improved entropy characteristics over versions 1 or 6.

If your use case requires greater granularity than UUID version 7 can provide, you might consider UUID version 8. UUID version 8 doesn't provide as good entropy characteristics as UUID version 7, but it utilizes timestamp with nanosecond level of precision.

Functions

uuid6.uuid1_to_uuid6(uuid1)

Generate a UUID version 6 object from a UUID version 1 object.

uuid6.uuid6(node=None, clock_seq=None)

Generate a UUID from a host ID, sequence number, and the current time. If node is not given, a random 48-bit number is chosen. If clock_seq is given, it is used as the sequence number; otherwise a random 14-bit sequence number is chosen.

uuid6.uuid7()

Generate a UUID from a random number, and the current time.

uuid6.uuid8()

Generate a UUID from a random number, and the current time.

UUID Version 6

UUID version 6 is a field-compatible version of UUIDv1, reordered for improved DB locality. It is expected that UUIDv6 will primarily be used in contexts where there are existing v1 UUIDs. Systems that do not involve legacy UUIDv1 SHOULD use UUIDv7 instead.

UUID Version 8

UUID version 8 provides an RFC-compatible format for experimental or vendor-specific use cases.

This implementation of uuid8() sacrifices some entropy for granularity compared to uuid7(), while being otherwise compatible.

unix_ts_ms: 48 bit big-endian unsigned number of Unix epoch timestamp with millisecond level of precision
ver: The 4 bit UUIDv8 version (1000)
subsec_a: 12 bits allocated to sub-second precision values
var: 2 bit UUID variant (10)
subsec_b: 8 bits allocated to sub-second precision values
rand: The remaining 54 bits are filled with cryptographically strong random data

20 extra bits dedicated to sub-second precision provide nanosecond resolution. The unix_ts_ms, subsec_a, and subsec_b fields guarantee the order of UUIDs generated within the same nanosecond by monotonically incrementing the timer.
