Oracle Coherence 12cR2 Offers Major New Innovations

We are very happy to announce major new innovations with the release of Oracle
Coherence 12.2.1 This release is one of the
largest we have done and delivers several major features aimed at both
developers and operations that improve developer productivity, support
infrastructure consolidation, provide better security, and simplify
multi-datacenter solutions. We are also
announcing a new licensing option for low-cost deployment of small-to-medium
sized deployments.

New Features

Coherence 12.2.1 is packed with major new features and
capabilities:

• The new Persistence
  feature enables Coherence to be a system-of-record and improves time-to-recovery from planned or unplanned, partial or total,
  cluster outage. Persistence can be configured
  to work in an on-line mode persisting changes as they are made to the cluster,
  or to take a snapshot of a data grid. Local disk configuration maximizes scalability, while network-attached
  storage maximizes availability.   Both
  data and metadata (indexes, listeners, expiry, locks, etc.) are stored, and
  recovery is completely automatic.

• Federated Caching
  provides support for Active-Active, Active-Passive, Hub and Spoke, and custom
  multi-datacenter topologies. Implemented at the lowest level of Coherence,
  Federated Caching takes advantage of Message Bus, Elastic Data, and our new
  Persistence feature to improve scalability, durability, latency, and
  configurability of data replication over prior solutions.  

• Coherence Multitenancy
  allows WebLogic Server Multitenant applications to share a cluster across a
  set of tenants and applications, consolidating infrastructure
  requirements. Multitenancy provides
  tenant-specific caches as well as shared caches for hosting reference data.  It is fully integrated with Oracle Traffic
  Director, WebLogic Server, and the Oracle Database to provide an end-to-end multitenant
  solution.

• One of our most exciting new features is the integration we
  have done with Java 8 to provide Distributed Lambdas and Streams. We now provide the ability to execute Lambdas
  and Streams remotely, using standard Java 8, distributed across cluster
  members, without the need to deploy code on cluster servers. This provides the ability to do distributed,
  parallelized stream-based functional programming.  By reducing the need to deploy classes to
  servers, we have also greatly simplified application upgrade.

• New Security Features include the ability to do fine-grained Authorization and Auditing of all cache access and updates.   We have also improved our SSL support.

• For developers, we have also added support for Asynchronous Cache operations via Java 8 CompletableFutures for quicker,
  parallel execution of multiple tasks as well as a Streaming Async API to improve performance and reduce memory
  pressure on bulk reads. We also offer improved Generics Support.

• Customers will notice increased
  performance from near cache optimizations and automatic, dynamic thread
  pool tuning. 

• We have improved
  cluster and port management, and switched data communications to run over
  TCP via the TCP Message Bus. We also
  provide Dynamic Coherence Management Node for Management HA.

• We also have a number of other goodies, including support
  for Sliding Expiry, a new cache truncate operation, REST Server-Sent Events, and JSON Passthrough that improve the developer experience and offer new functionality.

New Packaging and
Licensing Options

We also offer new (and sometimes free!) options for deploying Coherence in production.
