As you may have noticed we’re going for a major milestone on our Workbench 5.1 roadmap. So our resources are pretty much concentrated on this  task at the moment. But it’s just as important to keep improving our 5.0 GA version, so we will reserve the first days next week to make progress here as well. We will publish the next release of 5.0 mid-next-week. So stay tuned for a better 5.0 next week and the upcoming 5.1 alpha later this month.

Valleywag reports that Monty Widenius has quit Sun. The Pythian Group reckons its true. Kaj Arno’s non-denial denial would appear to confirm it despite his protestations otherwise.

“Technically there is no resignation letter. However, I spoke to Monty yesterday, and yes, resignation is an option he considers,” writes Kaj before expanding on some of the reasons that Monty might consider leaving Sun and how the MySQL project would continue without him (or without him as an employee at any rate).

He concludes: “In summary, I can neither confirm nor deny the rumour. But I hope my posting has shed some light on the …

We have a rumour of MySQL co-founder Michael “Monty” Widenius resigning, as posted by Valleywag and expanded by Sheeri Kritzer Cabral.

Usually, I wouldn’t comment on rumours. But as I’ve been asked copious amounts of questions, let me make an exception today.

First, it’s a rumour. Technically there is no resignation letter. However, I spoke to Monty yesterday, and yes, resignation is an option he considers.

Second, Monty’s resignation has been a possible outcome already since years before the Sun acquisition. Perhaps his resignation at some point is inevitable, given that the type of skills and qualities needed to make MySQL great are different from those needed for …

Electing a slave as new master and aligning the other slaves to the new master

In a simple MySQL Replication set-up you have high-availability (HA) on the read side (r). But for the master which covers all the writes (w) and the time critical read (rt) there is no HA implemented. For some situations this can be OK. For example if you have rarely writes or if you can wait until a new Master is set up.

But in other cases you need a fast fail-over to a new master.

In the following article it is shown how to implement the election of a new master and how to align the slaves to the new master.

We can have two possible scenarios:

1. This scenario assumes, that every slave can become the new master.
2. This scenario assumes, that only one dedicated slave will become master.

The advantages and disadvantages of both scenarios:

Scenario 1

On monday I gave a presentation at MySQL user group meeting in Hamburg on the team I’m working for: the MySQL Connectors team. The presentation was given in german. Unfortunately about 99.99999% of all PlanetMySQL had no chance to join the meetup, but you can find the slides (german language) here for download (PDF).

Valleywag is reporting that Michael ("Monty") Widenius, primary author of the original MySQL database and one of the company's founders, turned in his resignation to Sun yesterday. For those inside the MySQL team at Sun, this will likely prove bittersweet.

Bitter, because Monty has been such an important architect ...

Following the recent news rumours about Monty leaving MySQL, I just wanted to tell you that Brian Aker is giving a keynote speech about "To Drizzle MySQL" on this year's International PHP Conference at Mainz, Germany which is happening from October 27th to October 31st:

If you want to join Brian's keynote and all the …
