Primary Key Generator Implemented In Python
Project description
Introduction
PkGen is a pk generator implemented using Python, who’s core algorithm derives from Mongo’s generation of ObjectId.
Basic Concept of ObjectId
A BSON ObjectId is a 12-byte value consisting of a 4-byte timestamp (seconds since epoch), a 3-byte machine id, a 2-byte process id(PID) and a 3-byte counter. Note tha the timestamp and counter fields must be stored big endian unlike the rest of BSON.
Install
2 ways to install PkGen:
- clone the repo to your machine, run setup.py
$ cd ~ && git@github.com:streethacker/pkgen.git $ python setup.py install
- using pip
$ pip install -e git+https://github.com/streethacker/pkgen@0.1#egg=pkgen
Start
