AntidoteDB open source
A planet scale, highly available, transactional database
AntidoteDB is a highly available geo-replicated key-value database. AntidoteDB provides features that help programmers to write correct applications while having the same performance and horizontal scalability as AP/NoSQL databases. Furthermore, AntidoteDB operations are based on the principle of synchronization-free execution by using Conflict-free replicated datatypes (CRDTs).
This project is an Open Source collaboration from my thesis at Sorbonne University, on the LightKone and the SyncFree European projects.
