Since the European Commission announced it was opening an in-depth investigation into the proposed takeover of Sun Microsystems by Oracle with a focus on MySQL there has been no shortage of opinion written about Oracle’s impending ownership of MySQL and its impact on MySQL users and commercial partners, as well as MySQL’s business model, dual licensing and the GPL.

In order to try and bring some order to the conversation, we have brought together some of the most referenced blog posts and news stories in chronological order.

Part one took us from the announcement of the EC’s in-depth investigation up to the eve of the communication of the EC’s Statement of Objections.

On the 24th of November I attended a talk given by one of of Sun's benchmark specialists , Dimitri Kravtchuk, at the Sun Solution Center of Paris.

The talk was simply called MySQL performance, and I was expecting, as many I suppose (the auditorium was packed !) tips and tricks on how to optimize a MySQL database. However I was quite positively surprised since the 3 hours session wasn't just a long list of tricks and “how to's” but was actually a journey through one and a half year of improvement of the InnoDB engine.

InnoDB could easily scale horizontally but not vertically. Horizontal scaling is the fact to put many small servers with each running a MySQL server (typically in a Master-Slave mode) where vertical scaling would be to put a unique MySQL server on a bigger server, expecting to get better performances. The latter is more and more needed given the multiplication of cores and threads within the CPUs even in entry level …

A new round of GPL-based BusyBox suits has been filed, targeting big names in electronics and IT. We’ve long covered these series of GPL-based suits and settlements, but this latest round comes at an interesting time for open source software and its licensing.

First, we have the backdrop of the Oracle-Sun-MySQL acquisition, with opponents arguing to the world and the European Commission, which is reviewing the proposed merger before approving it, in part that the GPL is, ironically, granting too much power to its user, in this case Oracle. I’ve been quoted in the press and honestly agree with …

There was much rejoicing recently as Google announced a change of heart and decided to release the source code to EtherPad, which it had previously acquired along with AppJet and had planned to shut down.

Krishnan Subramanian at Cloud Ave was certainly happy as it supported his theory that SaaS vendors should offer their software under an open source license or at least open source their app before they shut down.

I’m not going to argue with Krishnan’s first point – in fact I agree that there is a lot of value in SaaS vendors reducing risk and encouraging adoption by making an open source version of their software available. However I am less convinced by the latter argument. There is a fine line between life …

I’m taking part in two webinar’s this week that will likely be of interest to CAOS readers. On WednesdayI’m contributing to a webinar with EnterpriseDB on the subject of open source database adoption in the enterprise, while on Thursday I’ll be presenting a 451 Group webinar on data warehousing.

During the EnterpriseDB webinar we will provide recommendations for how organizations can effectively leverage open source software. Attendees will learn about open source software trends for 2010, top considerations when using open source databases, and best practices for successful deployments of open source software.

I’ll be providing some data points from our recent surveys on database adoption and …
