” One of the biggest challenges with any project of such a long duration is coping with change. There are many aspects to coping with change, including changes in requirements, changes in technology, vendor stability, changes in staffing and so on”–Jon Brumfitt. On May 14, 2009, the European Space Agency launched an Arianne 5 rocket [...]

Multi master topologies blues
Tungsten Replicator is a powerful replication engine that, in addition to providing the same features as MySQL Replication, can also create several topologies, such as
- all-masters: every master in the deployment is a master, and all nodes are connected point-to-point, so that there is no single point of failure (SPOF).
- fan-in: Several masters can replicate into a single slave;
- star: It’s an all-masters topology, where one node acts as hub which simplifies the deployment at the price of creating a SPOF.
The real weakness of these topologies is that they don’t come together easily. Installation requires several commands, and running them unassisted is a daunting task. Some time ago, we introduced a set of scripts (the Tungsten Cookbook) that allow you to install multi-master topologies with a …

“We went down the path of building Oracle NoSQL database because of explicit request from some of our largest Oracle Berkeley DB installations that wanted to move away from maintaining home grown sharding implementations and very much wanted an out of box technology that can replicate the robustness of what they had built “out of [...]

Overview
First off, the important news. Tungsten Replicator 2.1.0 was released
today.
You can download it and give it a try right now.
Second, I would say that I am quite surprised at how much we have done in this release. The previous release (2.0.7) was in February, which is just a few months ago, and yet it looks like ages when I see the list of improvements, new features and bug fixes in the Release Notes. I did not realized it until I ran my last batch of checks to test the upgrade from the previous release, which I hadn’t run for quite a long time. It’s …

In my prior post on the problems with open source, I wrote that one issue that impacts open source revenues is the macro economy, and how a declining or difficult macro economy can result in reduction of revenues to open source companies. The following article talks about how financially troubled Spain is saving a "fortune" by moving to open source. The Spanish government's savings are coming at the expense of proprietary server software companies--most likely Microsoft--but I would be willing to bet that none of this "savings" is flowing to the open source vendors. That is what happens in a difficult macro economy.

I was reviewing the Percona Live sponsors list the other day and pondering the potential success stories associated with this product or that one…. and as I was preparing to put more thought on the topic, a PlanetMySQL post caught my eye. It was penned by Mike Hogan and titled, “Thoughts on Xeround and Free!”
For some reason the author of that post makes a connection between a free account in a cloud-based service and Open Source software. I think it’s an incorrect analogy, as they are two totally different things. A “free account” in this case is really just a marketing tool. Well, I admit there are companies that also use the “Open …

Everybody loves free. It is the best marketing term one could
use. Once you say “FREE” the people come running. Free makes you
very popular. Whether you are a politician offering something for
free, or a company providing free stuff, you gain instant
popularity.
Xeround is
shutting down their MySQL Database as a Service (DBaaS) because their
free instances, while popular, simply did not convert into
sufficient paid instances to support the company. While I am sad
to see them fail, because I appreciate the hard work required to
deliver database technology, this announcement was not
unexpected.
My company was at Percona Live, the MySQL conference, and I had
some additional conversations along these same lines. One
previously closed source company announced that they were open
sourcing their code, it was a very …
