Open Source Linux Distributed Computing Software

Blazegraph has moved to Github. Please see https://github.com/blazegraph/database/.

Sqlcached is a memory cache daemon, inspired by memcached, but offering more granular control by using SQL interface instead of key-value pairs.

UnixODBC.pm provides a Perl API for the unixODBC driver manager and a bridge API for unixODBC network queries. The sample text-mode, GUI, and Web clients can manage multiple hosts and DBMSs and create RSS output.

Cheshire3 is a fast Z39.50, SRW, XML search engine, written in Python for extensability and using C libraries for speed. Next generation of the Cheshire system (http://cheshire.berkeley.edu) and designed around a distributable, object oriented model.

A framework for building, deploying and managing well-described REST-ful Web services, including REST-ful Web Services realizations for RSS, XML Topic Maps, Structured Arguments, and Workflow.

Atomatrix is a multithreaded execution system of atomic matrices with a dynamic compiler and a network eviron. It is the next generation object-orientated environment. XML, MUD-OO CLI, GnucDNA support, windows and many subprojects are built-in.

Askemos is an autonomous, distributed operating system, which significantly raises the level of abstraction in comparison with todays operating systems. An alternativ, equally valid view is that of an XML object store with procedures in XSLT.

JCA compliant connectors for the Berkeley Database system.

Brain Net. A Distributed Search Engine Network. Aims to be a scalable distributed search engine allowing dynamic connection of nodes. Performance depends on bandwidth.

A unique persistence layer for Java. CODO (Cursor Oriented Data Objects) maps generated Entity interfaces (suitable for DTOs) to a relational database via rendered SQL, reflection and JDBC Cursors where possible - avoiding associations.

CloudBase is a data warehouse system for Terabyte & Petabyte scale analytics. It is built on top of Map-Reduce architecture. It allows you to query flat log files using ANSI SQL. Visit CloudBase home page for details- http://cloudbase.sourceforge.net

Moved to sf.net/projects/cloveretl/ !!! CloverETL is a Java ETL framework which transforms structured or unstructured data. Works as a standalone application or embedded in other applications as a data transformation library of functions.

DBReplicator is a powerful open-source java application for network-based multi-master heterogeneous database replication or filtered synchronization.

EmGeeGen is a server-client information distribution system, tailored for use with the EmGee role playing system (though the theoretical platform should be useful for a variety of tasks).

The JProgress project provides tools for connectivity with Java clients and the Progress database. JProgress provides an n-tier software architecture for database access for executing remote requests over WANs and the Internet.

Jirafa is an adaptive filtering system for real-time streamed data. It can be used for analyzing and monitoring market securities, road sensors, network routing information, etc.

Latis is a distributable storage engine for the semantic web. We plan to build a cross-platform, high-performance server that enables users to build private clouds which are protocol-compatible with popular web service offerings from Google & Amazon.

Postgres-XL is a PostgreSQL-based scale-out cluster that handles both OLTP write intensive workloads as well as OLAP/BI type of workloads thanks to MPP parallelism. Postgres-XL is fully ACID and supports cluster-wide Multi-version Concurrency Control (MVCC) for global consistency and performance. There are commercial companies such as 2ndQuadrant, who provide support and consulting around Postgres-XL. Please visit http://2ndquadrant.com/en/resources/postgres-xl/ for more details.

Ridiculously simple, Prevayler provides transparent ACID persistence and replication for plain old Java objects. It is literally several thousand times faster than using a relational database through JDBC.

Database replication software, based on a group messaging layer.

XSpace is a globally accessible repository for hierarchically-keyed information. It provides persistence for trees with an elegant tree-navigation API. XSpace also publishes real-time events whenever a persisted tree is updated.

Healthcare Xchange Protocol for interoperative communications. Data exchange/transfer, platform independent,XML-RPC, HL7, SOAP, EDIFACT, simple,easy, authenticated, secure, transparent, no geo-restrictions, open sourced, peer reviewed, collab development

The iChilli mobile J2EE platform provides a J2EE compliant runtime environment for both server and mobile platforms, such as J2ME, MIDP or other CLDC based devices. For example iChilli runs on the PersonalJava enabled Sharp Zaurus and Compaq's iPAQ.

A collection of implementations of the Paxos and FastPaxos algorithms for solving consensus in a network of unreliable processors. Visit http://libpaxos.sourceforge.net/ for more informations

unique.timestamp provides a universally unique identifier which is also a human-readable timestamp. It includes a command line executable, a set of C routines for embedding into your own code, and some utilities for manipulating unique timestamps.
