Features:

• Re-newal of JavaSpace technology based on disruptor/off-heap/spring API/guava/kryo libraries with user-friendly API and simple configuration
• OffHeap memory solution not bound and is not restricted by the java heap space similar to SUN's DirectBuffer with minimal GC impact(0.2-0.5% of JVM time) capable to handle millions transactions per second on standard (pretty cheap) environment running on any platform - pure java code without JNA or JNI.
• Guava's Cache off-heap interface implementation
• Spring's 3.1 Cache off-heap interface implementation
• In-memory object oriented transactional database with advanced access patterns(exclusive reads,locks with timeouts, etc)
• User-controlled data partitioning and native integration with databases with dynamic failover(without typical backup replications between nodes in cluster)
• Elastic external data source bindings - JPA/MongoDB/JDBC/Redis or any other storage support by spring-data.
• Distributed and persistent implementation of JavaSpace API.
• Powerful event-driven remoting via synchronous remote method invocation(don't confuse with RMI) or either asynchronous via write/notify message delivery model.
• Support for message driven exchange pattern (integration with JMS API).
• Unlimited and linear scalability.
• Powerful web-based monitoring system and alerting engine(also can be exposed through JMX).
• Distributed Lock/Executor Service.
• Multicast and unicast discovery.
• Tight integration with spring framework (namespace, transaction management, lifecycle, events, caching layer).
• Super small: near 250 KB
• Customizable for concrete scenarios in terms of serialization, network communications, database integrations
