bparmentier / pydruuid

A date-relative UUID generator.

Python Druuid

A python implementation of a date-realtive (and relatively universally unique) UUID generator. It is based on the original implementation in Ruby.

Concept

Druuid's are a 64 bit identifiers which are sortable since they are time based. A druuid is compromised of 2 blocks:

• 41-bit timestamp in miliseconds since epoch
• 23 random bits

For example, a druuid generated on 2016-05-16 might look like 12276209757600130011.

In binary: 10101010010111011101101110111011011111011 11100001010001111011011

In base 36: 2L9OH62W41ES0

Examples

>>> from druuid import Druuid
>>>
>>> d = Druuid()
>>> d.druuid
12276209757600130011
>>> d.time
'Mon May 16 15:37:23 2016'
>>>
>>> d = Druuid(12276215031090144168)
>>> d.time
'Mon May 16 15:47:52 2016'
