Open Source C Clustering Software

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.

Postgres-XC is a write-scalable synchronous multi-master PostgreSQL cluster with the following features. 1) Both read and write scalability. 2) Configured with more than one server. 3) Complete global transaction and visibility management.

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

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.

See http://www.cubrid.org/cluster. CUBRID Cluster is an open source clustered DBMS for high scalability including global schema, distributed partition and load balancing features. It is a spin-off project from CUBRID project and supported by NHN.

DBD2 inserts database records from TCP input. It is a companion project to Syslgod2 and an application in its own right. It ships with a backgrounding client for generic use. The client sends whatever information the user puts on the command-line to the back-end daemon via TCP. Upon successful transmission, the client exits. On failure, it backs off and retries until its life-time timer expires. The back-end daemon accepts data from Syslogd2 or its own client and inserts that data (and envelope information) into one or more databases using MySql client library or dbi drivers (also on SourceForge). The client needs no configuration (all input is via command-line). It is intended for hosts to make database entries without needing database client or interface code. Syslogd2 integration allows DBD2 to act as Syslogd2's database back-end for MySql and other databases supported by the dbi drivers. Original purpose was to track Linux cluster job status but other uses exist.

set of utilities that provide high availability for databases using the mysql database server. includes ip address takeover, using a master node and a slave one. please send you feature requests to fipar@seriema-systems.com

A fast, modular, scalable, adaptable and cheap enterprise back-end for information management. Includes database functionality (hybrid IMDB), process management, business integration, etc. by the way of custom extensions to the system.

The Open Design and Integration Environment is a toolbox of C and TCL code designed to introduce people to programming in a friendly way. It is also designed to be robust enough to novices to develop useful applications.

dFront is a frontend which makes it possible to distribute a msql database over several sites. It builds on a Transaction Manager (TM) and a Lock Manager (LM).

Ndbtop is a curses based lightweight tool for monitoring a MySQL Cluster / NDB system. Ndbtop constantly monitors the Cluster and provides access to simple operations.
