Hazelcast Community Edition 2.4

Hazelcast Community Edition is an open source and highly scalable clustering data distribution platform for Java.

Hazelcast Community Edition is for you if you want to:
? share data/state among many servers (e.g. web session sharing)
? cache your data (distributed cache)
? cluster your application
? partition your in-memory data
? distribute workload onto many servers
? take advantage of parallel processing
? provide fail-safe data management

Hazelcast is pure Java. JVMs that are running Hazelcast will dynamically cluster. Although by default Hazelcast will use multicast for discovery, it can also be configured to only use TCP/IP for enviroments where multicast is not available or preferred. Communication among cluster members is always TCP/IP with Java NIO beauty.

Default configuration comes with 1 backup so if one node fails, no data will be lost. It is as simple as using java.util.{Queue, Set, List, Map}. Just add the hazelcast.jar into your classpath and start coding.

Here are some key features of "Hazelcast Community Edition":

? Distributed implementations of java.util.{Queue, Set, List, Map}
? Distributed implementation of java.util.concurrency.locks.Lock
? Distributed implementation of java.util.concurrent.ExecutorService
? Distributed Topic for publish/subscribe messaging
? Transaction support and J2EE container integration via JCA
? Dynamic HTTP session clustering
? Support for cluster info and membership events
? Dynamic discovery
? Dynamic scaling to hundreds of servers
? Dynamic partitioning with backups
? Dynamic fail-over

Requirements:

? Java

? Client threads is no longer fixed size, now on it is going to use internal Hazelcast cached thread pool.
? Added ability to restrict outbound ports that Hazelcast uses to connect other nodes. See OutboundPorts documentation.
