Oracle has announced an open source product for the NoSQL space, the Oracle NoSQL Database. Unlike other popular products including Redis, MongoDB, Cassandra, Voldermort and many others, Oracle has set a benchmark on the features that are truly necessary for highly available data systems.

Many products in the NoSQL space have told you that consistency is not needed, eventual consistency is good enough, that transactions are not performant enough to include as a feature. No standards exists, there is no common interface for communication, or key features that products aim to meet or better. With this product, features including transactions, replicated data and failover which are built in, are features other open source NoSQL products will need to match.
