La empresa Volt acaba de lanzar VoltDB OLTP, un gestor de BBDD relacional de nueva generación. Es OpenSource y destaca la gestión de datos en memoria en vez de disco. VoltDBha demostrado que puede procesar transacciones 45 veces más rápido que MySQL, Oracle, PostgreSQL ..., unas 53.000 transacciones/s frente a las 1.155 de otros DBMS sobre hardware idéntico.
Puedes descargar VoltDBde forma gratuita bajo licencia GPL, aunque existen otras versiones de pago en www.voltdb.com/pricing.

Footnotes:
* CentOS 5.4 is the only officially supported operating system for VoltDB. However, VoltDB is tested on several other POSIX-compliant and Linux-based operating systems, including Ubuntu and Macintosh OSX 10.5 and 10.6.
** Dual-core processors are a minimum requirement. Four or eight physical cores are recommended for optimal performance
*** Memory requirements are very specific to the storage needs of the application and the number of nodes in the cluster. However, 4 Gigabytes should be considered a minimum configuration.
**** NTP minimizes time differences between nodes in a database cluster, which is critical for VoltDB. All nodes of the cluster should be configured to synchronize against the same NTP server. Using a single local NTP server is recommended, but not required.
