On Thursday 23rd January, Thomas Nielsen and I will be hosting a webinar explaining the latest developments in managing MySQL Cluster. As always the webinar is free but please register here.

Note that we’ll be covering what’s new in MySQL Cluster Manager 1.3 which went GA this week.

By their very nature, clustered environments involve more efforts and resources to administer than standalone systems and this holds true for MySQL Cluster, the database designed for web-scale throughput with carrier-grade availability.

The MySQL Cluster Auto-Installer guides you through defining and running a well configured MySQL Cluster database – …

From a Tumblr engineering blog post:

Tumblr is one of the largest users of MySQL on the web. At present, our data set consists of over 60 billion relational rows, adding up to 21 terabytes of unique relational data. Managing over 200 dedicated database servers can be a bit of a handful, so naturally we engineered some creative solutions to help automate our common processes.

Today, we’re happy to announce the open source release of Jetpants, Tumblr’s in-house toolchain for managing huge MySQL database topologies. Jetpants offers a command suite for easily cloning replicas, rebalancing shards, and performing master …

Communicating well and knowing when to step in or stand back is the linchpin of successful consulting.
Some people have natural charm. If you’re one of these people you’ll find consulting is definitely for you. You’ll use that skill all the time as each new client brings a half dozen or a dozen new people to interact with.

If it doesn’t come easily, practice practice practice. Try to get out of your own head space, and hear what troubles …

I've been to many jobs, either VPE or CTO.

When I joined Continuent, at the end of 2010, I was fascinated by the technology of its core products. Readers of this blog know that I have had my hands full with Tungsten Replicator, but what really turned me on was the flagship management suite, Tungsten Enterprise. After hammering at it for several months, and always marveling at the beauty of its technology, let me give a tour of the suite, so that you'll understand what's so exciting about it. First off, Tungsten Enterprise is not simply a replication tool. It is based on replication, but it is mostly a data management suite. Its aim is to reduce complexity for the user and to show a database cluster to the user as if it were a single server, always on, no matter what happens. The most amazing things that you will see in Tungsten Enterprise are

• Automatic failover
• Cluster console, and …

Clustered computing brings with it many benefits: high performance, high availability, scalable infrastructure, etc. But it also brings with it more complexity.

Why?

Well, by its very nature, there are more “moving parts” to monitor and manage (from physical, virtual and logical hosts) to clustering software to redundant networking components – the list goes on. And a cluster that isn’t effectively provisioned and managed will cause more downtime than the standalone systems it is designed to improve upon.

When it comes to the database industry, analysts already estimate that 50% of a typical database’s Total Cost of Ownership is attributable to staffing and downtime costs. These costs will only increase if a database cluster is not effectively monitored and managed.

Monitoring and management has been a major focus in the development of the …

Join us for a live webinar and download a new whitepaper where we discuss how to realize new value from data collected during web session management.

Session management has long been a key component of any web infrastructure – enhancing the user browsing experience through improved reliability, reduced latency and tighter security.

Increasingly organizations are looking to unlock more value from session management to further improve user loyalty (i.e. making the web service more “sticky”) and improve monetization of web services.  There are two distinct developments that offer the promise of unlocking more value from session data:
1.    Provide highly personalized browsing experiences by …

After Sun Microsystems was acquired by Oracle, there has been a large amount of discussions in the business and developer community on the future of MySQL community involved in its development.

A Community Fork?

Interestingly, MySQL community has been able to create a new Database by a fork from the public branch and has revived the project as MariaDB.

On it’s website, AskMonty.org [founded by Michael “Monty” Widenius, the founder and creator of MySQL] states that its aim is,

To provide a community developed, stable, and always Free branch of MySQL that is, on the user level, compatible with the main version. We strive for total interoperability with both our own, and our upstream, communities.
