The new Tungsten 1.2.2 release contains mostly bug fixes in the open source version but there are also two very significant improvements of interest to all users.
The commercial Tungsten Enterprise 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.
- 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.
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.
