pkgen 0.1

Primary Key Generator Implemented In Python

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.
