Infinispan

Infinispan is a distributed cache and key-value NoSQL data store software developed by Red Hat. Java applications can embed it as library, use it as a service in WildFly or any non-java applications can use it, as remote service through TCP/IP.

History
Infinispan is the successor of JBoss Cache. The project was announced in 2009.

Features

 * Transactions
 * MapReduce
 * Support for LRU and LIRS eviction algorithms
 * Through pluggable architecture, infinispan is able to persist data to filesystem, relational databases with JDBC, LevelDB, NoSQL databases like MongoDB, Apache Cassandra or HBase and others.

Usage
Typical use-cases for Infinispan include:


 * Distributed cache, often in front of a database
 * Storage for temporal data, like web sessions
 * In-memory data processing and analytics
 * Cross-JVM communication and shared storage
 * MapReduce Implementation in the In-Memory Data Grid.

Infinispan is also used in academia and research as a framework for distributed execution and storage.
 * Cloud2Sim leverages Infinispan for its distributed execution of MapReduce workflows and simulations.
 * MEDIator data sharing synchronization platform for medical image archives leverages Infinispan as its distributed in-memory storage, as well as distributed execution framework.
 * Cassowary uses Infinispan to store the context information in-memory, in order to provide the middleware platform for context-aware smart buildings.
