Introduction

An abstraction layer for NoSQL Database with features used in the financial services industry.

• Simple factory. A single URL would define the database or union.

• Filesystem-like hierarchy for objects.

• Caching and cache context.

• Union: i.e. multiple databases where:

  • Read would look for the object in order

  • Write always writes to the first (front) db

• Serialisable objects. Any python object can be stored in the DB with

  • With option to use decorators to give finer control over serialisation.
