caching driver

The caching driver doesn't directly provide storage. Instead, it provides a storage pattern -- using fast and easy storage for quick retrieval, and slower storage for long-term persistence.

Hopefully using this driver will keep you from having to write caching code in your own app.

Usage

To create a caching databank, use the Databank.get() method:

var Databank = require('databank').Databank;

var db = Databank.get('caching', {cache: {driver: 'memory', params: {}},
                                  source: {driver: 'disk', params: {dir: '/var/lib/mine/'}}});

The driver takes the following parameters:

• schema: the database schema, as described in the Databank README.
• source: the source databank info. Must be an object with driver and params properties.
• cache: the cache databank info. Must be an object with driver and params properties. If not set, a new memory databank will be used.
