Something technical for a change...


Tangosol CoherenceT:
In-memory caching and data management for clustered J2EE applications.

Tangosol Coherence is a JCache-compliant in-memory caching and data
management solution for clustered J2EE applications and application servers.
Coherence makes sharing and managing data in a cluster as simple as on a
single server. It accomplishes this by coordinating updates to the data
using cluster-wide concurrency control, replicating and distributing data
modifications across the cluster using the highest performing clustered
protocol available, and delivering notifications of data modifications to
any servers that request them. Developers can easily take advantage of
Coherence features using the standard Java collections API to access and
modify data, and use the standard JavaBean event model to receive data
change notifications. Functionality such as HTTP session replication is
available out-of-the-box for applications deployed to WebLogic 7, WebSphere
4, Tomcat 4, and all Servlet 2.3-compliant application servers.

Release 2.1 contains a number of improvements, including:
A clustered Invocation Service for grid and cluster computing
Configurable Cluster Node Authorization for secure applications
Performance improvements for distributed Cache Queries
Significant reduction in memory usage in the WAN Compression Filter
Hardening of the cluster start-up processing
We would like to thank those customers that helped up shape and validate
this release, and in particular our friends at, ESRI, GEICO,
Capital Group Companies and Jive Software.
