Open Source 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.

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.

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

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

Cloud Target is a front-end to the python scripts that google uses to create, run and upload projects to its App Server system. This .NET application is based on the OSX front-end provided by Google in the SDK.

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.

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.

The JotScale project is a cluster of servers implementing a highly scalable object storage system combined with a high performance http server and a subscription system. Jotscale now depends upon Mojasi (same trunk). Pure Java. Source only.

Khashmir is a distributed hash table library of the Kademlia flavor implemented in Python.

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.

A p2p based network management tool/database. The intention of the project is to create a flexible, improvable network interface to higher-level applications, such as a distributed database. The project may contain libraries and applications.

Ohua is an implementation of the stateful functional programming model along with a dataflow execution engine as a runtime system. Ohua mixes object-oriented (imperative) and functional programming to provide implicit parallelism. The project moved. Please find the most up-to-date version at: https://bitbucket.org/sertel/ohua

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.

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.
