#Catatumbo - Object Mapping and Persistence Framework for Google Cloud Datastore Catatumbo is an Open Source persistence framework for mapping Java objects (POJOs) to Google Cloud Datastore and vice versa.

Catatumbo framework is built on top of gcloud-java-datasource API. The framework provides a handful of annotations to make your model classes manageable by the framework. In other words, Catatumbo is similar to JPA (Java Persistence API), but is specifically designed to work with Google Cloud Datastore instead of Relational Databases.

Note: Catatumbo is a work-in-progress and future changes are not guaranteed to be backward compatible
