CloudDS - Cloud Data Stores - is an IT project in which ATNoG collaborates with Altice Labs in the European project CohereentPaaS.

CoherentPaaS provides a full ACID coherent environment integrating NoSQL, SQL and CEP (Complex Event Processing) data management technologies, while allowing application developers to program using a simple and powerful programming model and query language.

ChorentPaaS will provide:
1- Coherence (Transactional semantics across data stores): CoherentPaaS will
provide holistic coherence across data stores through a common transactional API to orchestrate transactions transparently to the applications.

2- Scalability (Ultra-scalable preserving ACID properties): CoherentPaaS will enable scaling to 100,000 transactions per second with full ACID transactional semantics and no sharding across heterogeneous cloud data stores.

3- Simplicity (Programming with a single query language): CoherentPaaS will develop a common query language for all cloud services and data stores, allowing access to all data stores in a uniform and integrated manner, hiding the complexity of the underlying technology under a unified query language.

4- Efficiency (Avoiding copying and translating TBs of data from one data store to another): CoherentPaaS will provide a rich PaaS with different “one size” data stores optimized for particular tasks, data, and workloads, eliminating the need for ETL jobs.

Altice Labs is responsible for the implementation of a use case which is based on the framework ALTAIA.
