LEADING OPEN SOURCE NEWSQL DATABASES
Created by DBMS R&D pioneer, Mike Stonebraker, VoltDB is a next-generation open-source DBMS that scales way beyond traditional databases, without sacrificing SQL or ACID for transactional data integrity. VoltDB is for database applications that support fast-growing transactional workloads and require:
– Orders of magnitude better performance than conventional DBMS
– Linear scalability
– SQL as the DBMS interface
– ACID transactions to ensure data consistency and integrity
– High availability 24x7x365
Postgres-XC is an open source project to provide a write-scalable, synchronous multi-master, transparent PostgreSQL cluster solution. It is a collection if tightly coupled database components which can be installed in more than one hardware or virtual machines.
Write-scalable means Postgres-XC can be configured with as many database servers as you want and handle many more writes (updating SQL statements) compared to what a single database server can not do.
OTHER OPEN SOURCE NEWSQL DATABASES
NuoDB is a NewSQL cloud database. It looks and behaves like a traditional SQL database from the outside but under the covers it’s a revolutionary database solution. It is a new class of database for a new class of datacenter.
Drizzle is a community-driven open source project that is forked from the popular MySQL database.
The Drizzle team has removed non-essential code, re-factored the remaining code into a plugin-based
architecture and modernized the code base moving to C++.
H-Store is an experimental main-memory, parallel database management system that is optimized for OLTP applications. It is a highly distributed, row-store-based relational database that runs on a cluster on shared-nothing, main memory executor nodes.
The H-Store project is a collaboration between MIT, Brown University, Yale University, and HP Labs.
MySQL Cluster is a write-scalable, real-time, ACID-compliant transactional database, combining 99.999% availability with the low TCO of open source. Designed around a distributed, multi-master architecture with no single point of failure, MySQL Cluster scales horizontally on commodity hardware with auto-sharding to serve read and write intensive workloads, accessed via SQL and NoSQL interfaces.
