This project provides an API which allows Aerospike CDT (Collection Data Type) objects to be accessed and mutated using JSON like syntax. Effectively this provides what can be termed a document API as CDT objects can be used to represent JSON in the Aerospike database.

There is a newer version: 2.0.3
