Scalar DB


A library that makes non-ACID distributed databases/storages ACID-compliant. It not only supports strongly-consistent ACID transactions, but also scales linearly and achieves high availability when it is deployed with distributed databases/storages such as Cassandra.



This library is mainly maintained by the Scalar Engineering Team, but of course we appreciate any help.
