Continuent Improves 24x7 Data Availability And Database Performance For PostgreSQL

New Tungsten Enterprise Improves Management, Performance, Ease Of Use And Reliability

SAN JOSE, CA – March 22, 2011 – Continuent, Inc., a leading provider of replication and clustering solutions for open source databases, today announced the availability of the next version of Tungsten Enterprise. Tungsten Enterprise is a complete replication and data management solution for PostgreSQL. Tungsten Enterprise uses replication and distributed management to create virtualized databases using redundant data copies.

This latest version of Tungsten Enterprise includes a number of features to improve the management, performance, flexibility and reliability of Tungsten clusters. Furthermore, it includes architectural changes to the Tungsten Replicator, connectivity improvements, upgrades to PostgreSQL replication, including:

Improved Performance

  • 5x boost in replication throughput.

  • New disk-based logging improves performance and simplifies log management.

Improved Management And Monitoring

-Enhanced failure detection logic allows for configurable confirmation. You can now configure more than a single check for aliveness and increase Tungsten's ability to avoid false triggering.

  • Redundant confirmation of database server failures. Failures will be confirmed once they are detected the first time to further ensure right automatic response upon failure.

  • New ‘monitoring by proxy'. In the case where a manager fails on a database host, you can still monitor and detect failures on a given host as long as there is at least one manager remaining.

  • Support of virtual IP addresses makes them easier to set up and manage. You now can configure the VIP address and Ethernet interface at installation time.

Improved Connectivity

  • New Tungsten SQL Router and Connector management protocols allow processes to run without a Tungsten Manager process on the same host. This greatly simplifies management for clusters with large numbers of application servers.

  • You can now specify URL options for all connections that go through the connector to a given IP address. This functionality allows you to configure the connector to always connect to an available slave.

Improved Replication

  • Significant architectural improvements allow Tungsten Replicator to define custom replication flows (pipelines) for native Tungsten Replication as well as to manage non-Tungsten mechanisms such as PostgreSQL warm standby replication.

  • Handling of non-English locales for PostgreSQL servers allows Tungsten to function more effectively in internationalized environments.

  • MySQL to PostgreSQL replication for real-time integration of applications running on PostgreSQL and needing MySQL data.

  • MySQL to Greenplum replication for real-time data warehousing from MySQL into PostgreSQL-based Greenplum.

"This release benefited from substantial customer participation and feedback, helping to provide a more broadly tested product. With Tungsten Enterprise 1.3.1, our customers have a high performance, reliable, scalable and cost-effective solution for building and deploying their business critical web applications," said Robert Hodges, CEO of Continuent. "Our consulting experts can assist with the upgrade, as well as solve other problems in replication and data management."

Tungsten Enterprise builds on Tungsten Replicator capabilities. Tungsten Replicator, a high performance, open source data replication engine, is available for a free download at http://www.continuent.com.
