PostgreSQL 9 - Tungsten Clusters with Hot Standby and Streaming Replication

Hot standby and streaming replication will move the needle forward for high availability and scaling for a wide number of applications. Tungsten already supports clustering using warm standby. In this talk we will describe how to build clusters using the new PostgreSQL features and give our report from the trenches

This talk will cover how hot standby and streaming replication work from a user perspective, then dive into a description of how to use these features and how Tungsten makes them truly shine.

We'll cover the following issues:

  • Configuration of warm standby and streaming replication
  • Provisioning new standby instances
  • Strategies for balancing reads across primary and standby database
  • Managing failover
  • Troubleshooting

Zero-Downtime Maintenance and Upgrade for MySQL

Within the increasing reliability of hardware and software, database maintenance and schema upgrade is now the biggest cause of avoidable downtime in business-critical systems in businesses ranging from SaaS to social networking to large enterprises.

CTO Robert Hodges of Continuent presents highly technical webinar (register at http://continuent.webex.com/) how Tungsten clustering allows you to achieve database administration nirvana: maintain hardware, migrate to new database versions, and upgrade SQL schema on MySQL without requiring a maintenance window.

Robert's talk will start out by introducing basics of large-system maintenance, including maintenance window concepts and a discussion of the types of maintenance tasks that you need to perform as well as the problems you need to overcome in order to avoid outages. He will also introduce Tungsten clustering and explain how it creates highly available clusters using copies of standard MySQL databases.

Robert will show you specific procedures to:
  • Maintain/replace existing hardware
  • Add capacity to current systems
  • Migrate MySQL databases to new versions
  • Upgrade application schema
He will conclude with a demonstration of SQL upgrade on a running application using the procedures described above. Please bring your questions and try to stump the Continuent database upgrade meisters. We look forward to seeing you.

Tungsten 1.3 Release Candidate Now Available

New Tungsten Enterprise v. 1.3 Release Candidate

Enterprise Version 1.3 is a major release that includes a number of features to improve the flexibility, speed, and reliability of Tungsten clusters. Version 1.3 also includes a large number of bug fixes and minor improvements.

Tungsten version 1.3 includes significant architectural improvements to allow Tungsten Replicator to define custom replication flows, or pipelines as we call them, for native Tungsten Replication.

For MySQL users Tungsten 1.3 adds extensions to MySQL replication capabilities including correct replication of session variables, processing of LOAD DATA INFILE statements, a fragmentation protocol for large transactions, ability to read binlog events from MySQL master servers using the MySQL client protocol, and finally commands to start replication at a user-selected location in the binlog.

These greatly improve replicator reliability and reduce to a minimum data loss in the event of master failures.

For PostgreSQL users Tungsten 1.3 also greatly improves PostgreSQL 8.4 warm standby clustering and introduces alpha support for the upcoming PostgreSQL 9 log streaming and host standby feature. With PostgreSQL 8.4 you can use a second PostgreSQL database as a warm standby backup with automatic failover upon master failure. With upcoming PostgreSQL 9.0, you can direct read traffic to standby databases, thereby enabling scale out solutions for PostgreSQL.

This major Tungsten release also has completely updated documentation, including expanded description on cluster concepts, management procedures, and connectivity options.

CTO Robert Hodges Speaking at MySQL UC 2010

Database replication is still interesting after all these years. Two of Robert Hodges' talks focused on replication technology has been accepted for the upcoming MySQL 2010 Conference. Here are the summaries.
The first talk is a presentation covering Tungsten, which creates highly available and scalable database clusters using vanilla MySQL databases linked by flexible replication. Robert will describe how Tungsten works and some cool things you can do like zero-downtime upgrades and session-based performance scaling.

The second talk is a joint effort between Robert Hodges and
Jay Pipes covering issues like big data that are driving replication technology and the solutions to these problems available to MySQL users. They'll lay out the vision of where things are going to try to help you pick the right technology for your next project.

Finally, Robert and rest of the Continuent team will be around for much of the MySQL conference, so if you are interested in Tungsten, database clustering or data replication in general or just want to hang out, please look Robert and the gang up. See you in Santa Clara!

Webinar: Secrets of Successful SaaS Database Architecture with Tungsten

SaaS application construction is a deep subject, and SaaS data design is no exception. Laying out the database and implementing properly can mean the difference between success and failure of the entire SaaS business. To do it well you need specially technologies like Tungsten but also time-tested design patterns that allow data to scale smoothly and economically.

this webinar we will focus on the design tricks for SaaS applications and how to implement them with Tungsten clustering. This includes setting up data services, deciding how to store customer data, and dealing with special issues like how to share global data effectively across servers containing customer data. We'll also talk about special topics like upgrade and failure handling, as well as automation and management.

Our talk is based on our experience helping a wide range of SaaS customers implement successful data management using Tungsten clustering. Tungsten deployments range from small start-ups to large applications containing hundreds of thousands of users. We hope you will benefit from our experience and learn how Tungsten can help with your SaaS data management.

Continuent Tungsten 1.2.2 Release is Available - Faster, More Stable, More Fun

The latest Continuent Tungsten Clustering release, version 1.2.2, is available at the Continuent software download site.

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 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 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.

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.
