POF annotations provide a simpler and often cleaner way to express POF indexes in a data model. In this
presentation Harvey explains how they work and looks and some of the more advanced concepts, like
codecs
REST is a great way to provide a very loosly coupled interface for client applications. Coherence
now provides a rich set of REST constructs for key, query, aggregation and processing operations,
all through a REST API. Furthermore, the data model can be expressed in both a JSON or XML format,
enabling easier integration with Javascript or SOA clients. Dave outlines how you can use the REST
API along with configuration and implementation details

performance of Coherence queries. Noah explains how to use this feature to optimise queries and index
usage for optimal performance
A Coherence partition is a basic unit of storage and distribution for a distributed cache. Understanding what
a partition, how they are used and movement is essential to appreciate how Coherence delivers a
reliable and scalable data grid platform. In this presentation Rob outlines the different events
and state changes associated with Coherence partitions.
Getting the best performance from Coherence requires understanding how Java manages memory. Simon Cook - with

real-time events to a whole range of end devices. Diffusion allows this to be done in a scalable
and virtually platform neutral fashion.
The 12c release of Coherence included a number of major product features, like HotCache and
Managed Coherence Servers. But there are a range of smaller and less well known improvements that
Harvey covers in this presentation, that can boost performance and simplify your application design.
Coherence*Web allows the state of Web applications (HTTP Sessions) to be caching in Coherence - without
modifying the Web application. This helps Web applications scale, makes the application server tier stateless,
lets separate applications share state between each other - for a more modular architecture - and
can unify completely separate application logic to provide a unified user experience. In this
presentation Mark explains how
Coherence 12c introduced a major new feature, Managed Coherence Servers. In this presentation Noah
walks through what they are and how to use them to make deploying and managing Coherence applicaions

database are synchronized in real-time, to ensure they always have the latest data in their cache.
Coherence 12c Live Events, what are they and how do they work
Coherence 12c introduced "Live Events". They
basically enable event based processing to take place inside the data grid and take advantage of
the scalability, reliability and performance capabilities of Coherence. In this presentation Harvey
explains what "Live Events" are and how to utilise them for your own event based processing.
