# cuid.py
|
|
|
|
Implementation of https://github.com/ericelliott/cuid in Python.
|
|
|
|
A `cuid` is a portable and sequentially-ordered unique identifier designed for
|
|
horizontal scalability and speed -- this version is ported from the reference
|
|
implementation in Javascript.
|
|
|
|
**NOTE**: Particularly if you have security concerns, the [`cuid` standard has been deprecated in favor of `cuid2`](https://github.com/paralleldrive/cuid2)!
|
|
|
|
Tested on CPython 2.7, 3.6-3.11 as well as PyPy & PyPy3.
|
|
|
|
Rough benchmarks on my machine (i7-8750H CPU @ 2.20GHz) using `setup.py bench`
|
|
(which times the creation of 1 million `cuid`s):
|
|
|
|
| Version | ns / cuid |
|
|
| -------------------------- | --------- |
|
|
| CPython 3.7.3 | 6095.257 |
|
|
| CPython 3.6.8 | 6846.050 |
|
|
| CPython 3.5.6 | 6604.012 |
|
|
| CPython 2.7.16 | 6913.681 |
|
|
| PyPy 7.1.1 (Python 2.7.13) | 326.344 |
|
|
| PyPy3 7.1.1 (Python 3.6.1) | 562.673 |
|
|
|
|
_(Note that timing the creation of fewer IDs changes the way PyPy runs the code, because of JIT warmup --
|
|
obviously creating this many IDs takes advantage of the warmed JIT)_
|
|
|
|
For now, this has no dependencies outside the standard library -- in time this may change,
|
|
to provide better random numbers and / or performance.
