Oracle Coherence

Oracle Coherence is the industry leading in-memory data grid solution that enables organizations to predictably scale mission-critical applications by providing fast access to frequently used data. As data volumes and customer expectations increase, driven by the “internet of things”, social, mobile, cloud and always-connected devices, so does the need to handle more data in real-time, offload over-burdened shared data services and provide availability guarantees. This release contains many new features that help reduce complexity, ease configuration, and accelerate time to market of scalable solutions. Just like the coherence persistence which is a set of tools and technologies that manage the persistence and recovery of Coherence distributed caches. Cached data is persisted so that it can be quickly recovered after a catastrophic failure or after a cluster restart due to planned maintenance. It also has federated caching which replicates and synchronizes cache data across multiple geographically dispersed clusters. Cached data is replicated across clusters to provide redundancy, off-site backup, and multiple points of access for application users in different geographical locations. Coherence includes new security functionality that includes Audit logs, Access control authorization, Additional JAAS permissions, and SSL Protocols and Cipher Suites. The Coherence API has been updated so that users can use programming features that were introduced in the Java 8 release. The features include lambda, streams, and default methods. These features provide ease of use and flexibility when performing data grid operations. Java Generics provide compile and runtime type checking together with compile type-inference. The Coherence API has been refactored to support Java Generics. In addition, types can be explicitly configured as part of the NamedCache API.
