Tungsten 1.2.2 Release is Out - Faster, More Stable, More Fun

Release 1.2.2 of Tungsten Clustering is available on SourceForge as well as through the Continuent website.  The release contains mostly bug fixes in the open source version but there are also two very significant improvements of interest to all users.
  • The manager and monitoring capabilities of Tungsten are completely integrated on the same group communications channel.  This fixes a number of problems that caused data sources not to show up properly in older versions.  
  • We are officially supporting a new Tungsten Connector capability for MySQL called pass-through mode, which allows us to proxy connections by transferring network blocks directly rather than translating native request protocol to JDBC calls.  Our tests show that it speeds up throughput by as much as 200% in some cases. 
The commercial version has additional features like PostgreSQL warm standby clustering, add-on rules to manage master virtual IP addresses and other niceties.   If you are serious about replication and clustering it is worth a look.

This is a good time to give a couple of reminders for Tungsten users.  First, Tungsten is distributed as a single build that integrates replication, management, monitoring, and connectivity.   The old Tungsten Replicator and Myosotis builds are going away.   Second, we have a single set of docs on the Continuent website that covers both open source and commercial distributions.

With that, enjoy the new release.  If you are using the open source edition, please post your experiences in the Tungsten community forums or write a blog article.  We would love to hear from you.

P.s., We have added Drizzle support thanks to a patch from Marcus Eriksson but it's not in 1.2.2.  For that you need to build directly from the SVN trunk.  Drizzle support will be out in binary builds as part of Tungsten version 1.3.

I want to know whether INHERITANCE in POSTGRESQL creates DUPLICATION of DATA in both the PARENT TABLE and CHILD TABLE(Inherited table)...?

Please inform me as soon as possible. So i can do more R & D in PostgreSQL.
