14. Carbon 4.3 - Carbon Clustering
improvements
o Distributed caching and clustering with Enterprise-grade software, Hazelcast.
o Introduced with Carbon 4.2
o Upgraded to Hazelcast version - 3.2.6
o Stabilization
“... the WSO2 Carbon core adds new distributed caching and
clustering implementations that are based on Hazelcast...
Hazelcast combines distributed data structures, distributed
caching capabilities, elasticity, memcache support, and
integration with Spring and Hibernate. These capabilities
bring several benefits to enterprise deployments, including
the ability to handle thousands of operations per second,
prevent the loss of data after crashes, and dynamically
scale as new servers are added.“ - Hazelcast
