memcached

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

ehcache

Ehcache is a widely used java distributed cache for general purpose caching, J2EE and light-weight containers. It features memory and disk stores, replicate by copy and invalidate, listeners, a gzip caching servlet filter and much more... Ehcache is available under an Apache open source ... [More] license and is actively developed, maintained and supported. [Less]

Apache CouchDB

claimed by Apache Software Foundation

CouchDb is a distributed document database system with bi-directional replication. It makes it simple to build collaborative applications that can be replicated offline by users, with full interactivity (query, add, update, delete), and later "synced up" with everyone else's changes when back online.

Redis

A persistent key-value database with built-in net interface written in ANSI-C for Posix systems.

monotone

monotone is a free distributed version control system. It provides a simple, single-file transactional version store, with fully disconnected operation and an efficient peer-to-peer synchronization protocol. It understands history-sensitive merging, lightweight branches, integrated code review and ... [More] 3rd party testing. It uses cryptographic version naming and client-side RSA certificates. It has good internationalization support, has no external dependencies, is written in C++, runs on Linux, Solaris, Mac OS X and other unixes, and Windows too. [Less]

JBoss Cache

JBoss Cache is a product designed to cache frequently accessed Java objects in order to dramatically improve the performance of applications. By eliminating unnecessary database access, JBoss Cache decreases network traffic and increases the scalability of applications. In addition, JBoss Cache ... [More] is a clustering library allowing you to transparently share objects across JVMs across a cluster. JBoss Cache provides three APIs to suit your needs. The Core API offers a tree-structured node-based cache. A POJO API provides the ability to perform fine-grained replication of Java objects, resulting in maximum performance benefits. Finally, a new Searchable API allows you to run object-based queries on the cache to search for cached objects. [Less]

CDO Model Repository

claimed by Eclipse Foundation

CDO Model Repository ===================== CDO is both a development-time model repository and a run-time persistence framework. Being highly optimized it supports object graphs of arbitrary size. CDO offers transactions with save points, explicit locking, change notification, queries ... [More] , temporality, branching, merging, offline and fail-over modes, ... The storage back-end is pluggable and migrations between direct JDBC, Hibernate, Objectivity/DB, MongoDB or DB4O are seamless for CDO applications. [Less]

pcp

Performance Co-Pilot (PCP) provides a framework and services to support system-level performance monitoring and performance management. The services offered by PCP are especially attractive for those tackling harder system-level performance problems. For example this may involve a transient ... [More] performance degradation, or correlating end-user quality of service with platform activity, or diagnosing some complex interaction between resource demands on a single system, or management of performance on large systems with lots of "moving parts". The distributed PCP architecture makes it especially useful for those seeking centralized monitoring of distributed processing (e.g. in a cluster or webserver farm environment), especially where a large number of hosts are involved.

Couchbase

The couchbase server and its components.

Apache Accumulo

claimed by Apache Software Foundation

Apache Accumulo is a sorted, distributed key/value store based on Google's BigTable design. It is built on top of Apache Hadoop, Zookeeper, and Thrift. It features a few novel improvements on the BigTable design in the form of cell-level access labels and a server-side programming mechanism that ... [More] can modify key/value pairs at various points in the data management process. [Less]
