Temporal UUID64

A time-based 64-bit UUID generator. The basic idea behind is to provide a universally unique identifier that satisfies the following conditions:

Installation

pip install temporaluuid64

Technical Details

The time-based UUID consists of two components: a timestamp and a node ID.

+----------------------+--------------------+
|  48-bit (timestamp)  |  16-bit (node_id)  |
+----------------------+--------------------+

Sort entities in chronological order

Entities given their UUIDs must be able to be sorted in chronological order without relying on additional data fields. This is why the timestamp bits occupy the most significant bits.

Suitable for distributed systems

Even if multiple identifiers are created at the exactly same time, given a particular granularity (generally a millisecond), the UUID generator must be able to provide a way to avoid collisions.
