Catatumbo is an Open Source Object Mapping and Persistence framework for Google's Cloud Datastore and Cloud Firestore 1. Catatumbo allows to effortlessly save model objects to the Cloud Datastore as well as retrieve and map the data from the Cloud Datastore to model objects. Catatumbo is similar to JPA (Java Persistence API), but is specifically designed to work with Google Cloud Datastore instead of Relational Databases.
