Open Source Java Clustering Software

MyCAT is an Open-Source software, “a large database cluster” oriented to enterprises. MyCAT is an enforced database which is a replacement for MySQL and supports transaction and ACID. Regarded as MySQL cluster of enterprise database, MyCAT can take the place of expensive Oracle cluster. MyCAT is also a new type of database, which seems like a SQL Server integrated with the memory cache technology, NoSQL technology and HDFS big data. And as a new modern enterprise database product, MyCAT is combined with the traditional database and new distributed data warehouse. In a word, MyCAT is a fresh new middleware of database. MyCAT ’s objective is to smoothly migrate the current stand-alone database and applications to cloud side with low cost and to solve the bottleneck problem caused by the rapid growth of data storage and business scale.

A JDBC driver proxy that adds light-weight, transparent, fault tolerant clustering capability to any underlying JDBC driver.

Momoko is a framework for developing distributed, multi-user, network-aware applications. It includes facilities for storing objects in a tree structure, a shell for manipulating the object database, orthogonal persistence, scripting support, and a trans

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.

Chordless is a Chord and DHash implementation written in java. It implements almost everything from Chord and DHash described at http://pdos.csail.mit.edu/chord/, as well as some extra features such as transactions and remote method invocation.

Cos provides a high level interface to application developers wishing to manipulate objects stored in a corportate wide data source lightweight data entries are manipulated by services that are able to appear and dissapear across the network as needed.

JReplica is a java distributed database replication system developed during a European Research Project in the department of Informatics of University "La Sapienza" of Roma under the supervision of Prof.ssa Catarci, Prof. Santucci and Ing. Curci.

LeverPack is a small, transaction based, secure, concurrent, and efficient record repository management engine written in Java. It provides READ_COMMITTED transaction isolation level supported read/write access to user data records.

NDB/J is a Direct Java API for storing and retrieving data from MySQL Cluster's NDB storage engine, without using the MySQL server. NDB/J has compiles on MySQL Cluster 5.0.x (tested on 5.0.37) and 5.1.16 and above.

By far the simplest and fastest petstore implementation. Available on CVS.

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.

Sequoia is a database clustering middleware offering load balancing and transparent failover. Databases are replicated over multiple nodes and Sequoia balances the queries between them. Sequoia supports online maintenance and recovery operations.
