* High throughput, low latency, cross process, persisted key value store. * Supports very high update rates by only replicating the latest value. * Off heap data storage, with micro second latency. * Designed to be used in Java, in a pause less, garbage free manner. * Easy to adopt and open source based on the ConcurrentHashMap. * Better utilizes your existing hardware by offering vertical scalability. * UDP support for high fan out. * TCP connectivity. * Concurrent writers on one machine using one copy in memory. * Concurrent multi-master writers across machines, with a reconciliation process. * Multiple readers with TCP and UDP replication. * Resilient writes (if a process dies, the last write is not lost.) * Entirely embedded, you don’t need any additional processes.

* Data can be modeled as relational-database-style tables, JSON documents or key-value pairs. * Oracle NoSQL Database is a sharded (shared-nothing) system which distributes the data uniformly across the multiple shards in the cluster, based on the hashed value of the primary key. Within each shard, storage nodes are replicated to ensure high availability, rapid failover in the event of a node failure and optimal load balancing of queries. * NoSQL Database provides Java, C, Python and node.js drivers and a REST API to simplify application development. * NoSQL Database is integrated with a wide variety of related Oracle and open source applications in order to simplify and streamline the development and deployment of modern big data applications. * NoSQL Database is dual-licensed and available as an open-source community edition as well as a commercially licensed Enterprise Edition.
