MySQL Connector/Net 6.2.2, a new version of the all-managed .NET driver for MySQL has been released.This is our latest GA release and is suitable for use in all scenarios against servers ranging from version 4.1 to 5.4!

It is now available in source and binary here and mirror sites (note that not all mirror sites may be up to date at this point of time – if you can’t find this version on some mirror, please try again later or choose another download site.)

The new features or changes in this release are:

• Connection pool cleanup timer.  We now utilize a timer that cleans idle connections that are no longer connected every 3 minutes
• We are now using stream and TCP-based timeouts to handle command timeouts.  This is more inline with what SqlClient does and should be more reliable than our old timer …

It finally dawned on me while reflecting on the year past this Sunday that the missing voice since the announcement of the Oracle acquisition of Sun Microsystems (and therefore MySQL) has been the MySQL employees.

When I worked as an employee for MySQL Inc, the acquisition by Sun Microsystems in 2008 lead to several requirements about the acquisition.

• You were not allowed to talk about the acquisition publically.
• You were not allowed to communicate with any Sun (i.e. the acquirer) resources.

In other words it was “business as usual” which is really an oxymoron, because business will never be exactly as it was before the announcement. The ongoing delay in pending acquisition by Oracle Corporation is really hurting everybody with getting on with doing their jobs, being happy with their work, and making a difference in open source and in the lives of all the benefit from using MySQL.

Cloud computing has been one of the most discussed topic over the year, and the discussion is not over because what is really being discussed is the way we will access computing an storage resources in the future. Even famous French intellectuals are giving their opinion and making predictions. Future will decide on predictions's accuracy.

What is usually less discussed is the technology behind cloud-computing, though this is no secret that virtualization is playing a key role. Cloud data-centers will be loaded with virtual machines each of these machines potentially requiring in disk-space what a complete operating system (OS) requires, which can go up to many gigabytes. How much disk-space does a virtual machine image (vdi) really consum? The only good answer is: too much. Too much because the OS is part of the infrastructure as …

For this year’s MySQL Conference (and by “this year”, I do mean 2009), I wrote the blog entry about opening the Call for Papers over three months earlier. The blog entry was in early September 2008, and the deadline was in late October 2008.

Next year, the MySQL Conference 12-15 April 2010 in Santa Clara has a tighter Call for Papers. It’s now open, and it closes 27 January 2010.

This has its drawbacks (a short time for you to propose, a short time for the program committee to review), but it also has a …

InnoDB detects deadlocks. Deadlocks are those nasty situations, when transaction 1 tries to acquire locks A and B, whereas transaction 2 tries to acquire locks B and A at the same time. As both are stubborn, InnoDB will decide simply to terminate one of them. If it wouldn’t do that, both transactions would have to wait until lock_wait_timeout to expire otherwise. There is a big chance that longer the transaction is, more likely it is to cause deadlocks. Deadlock detection kind of helps, then, but… at certain costs.

Transaction 1 and 2 case is way too easy, try adding few hundred transactions that contend over same set of locks. To do that, InnoDB deadlock monitor will recursively brute-force lock graph, until it hits a 200-transaction-long chain (it will say it is a deadlock), or until it runs out of paths to check. Still, with the power of modern hardware that will still be milliseconds.

Unfortunately, InnoDB will also hold …
