The SkySQL and MariaDB Roadshow comes to Sweden:
Stockholm 7 February 2013, 16:30-19:30, Dramaten Restaurang Pauli
SkySQL and Monty Program are on the road with our joint - free - roadshow in Stockholm where Monty Widenius will unveil his vision of the future of the MySQL database via MariaDB.
In addition, we will have speakers from Codership/Galera, as well as SkySQL experts.
451 Research’s 2013 Database survey is now live at http://bit.ly/451db13 investigating the current use of database technologies, including MySQL, NoSQL and NewSQL, as well as traditional relation and non-relational databases.
The aim of this survey is to identify trends in database usage, as well as changing attitudes to MySQL following its acquisition by Oracle, and the competitive dynamic between MySQL and other databases, including NoSQL and NewSQL technologies.
There are just 15 questions to answer, spread over five pages, and the entire survey should take less than ten minutes to complete.
All individual responses are of course confidential. The results will be published as part of a major research report due during Q2.

We have started a new series of webinars at Continuent that
we call Tungsten University. They provide education on
Tungsten clustering and replication in handy
one-hour chunks. These are not sales pitches. Our
goal is to provide accessible education about setting up and
operating Tungsten without any marketing fluff.
The first Tungsten University webinar entitled "Configure & provision Tungsten clusters" will take
place on Thursday January 17th at 10:00 PST. It will show
you how to set up a cluster in Amazon EC2. There will be a
repeat on January 22nd at 15:00 GMT. We usually record
webinars, so you can look at them later as well.
You do not have to be a customer to attend these webinars, …
I think it’s worth noting that since January 2012 there was no changes to MHA (0.53). Yoshinori Matsunobu made two releases in December (release notes), one in time for my Percona Live London 2012 talk. Thanks Yoshi! Totally download MHA 0.55 which is still be actively developed & used in production at multiple locations.

On 29 November last year, SkySQL and Monty Program jointly
announced the release of the so called "MariaDB Client
Library for C Applications" and "Maria DB Client Library for Java
Applications", which I will call C and JDBC connectors here. You
can follow this link to read the press release from
SkySQL.
Last week Baron Schwartz posted some findings re the C connector
in his blog. Today, another post from Robert Hodges added few details
and were looking for answers. I think I can help a bit in
understanding what we have released and how the …
I got some very good comments/questions on my previous post on MariaDB global transaction ID, from Giuseppe and Robert (of Tungsten fame). I thought a follow-up post would be appropriate to answer and further elaborate on the comments, as the points they raise are very important and interesting.
(It also gives me the opportunity to explain more deeply a lot of interesting design decisions that I left out in the first post for the sake of brevity and clarity.)
On crash-safe slave
One of the things I really wanted to improve with global transaction ID is to make the replication slaves more crash safe with respect to their current replication state. This state is mostly persistently stored information about which event(s) were last executed on the slave, so that after a server restart the slave will know from which point in the master binlog(s) …
[Read more]The main goal of global transaction ID is to make it easy to promote a new master and switch all slaves over to continue replication from the new master. This is currently harder than it could be, since the current replication position for a slave is specified in coordinates that are specific to the current master, and it is not trivial to translate them into the corresponding coordinates on the new master. Global transaction ID solves this by annotating each event with the global transaction id which is unique and universal across the whole replication hierarchy.
In addition, there are at least two other main goals for MariaDB global transaction ID:
The recent release of the MariaDB client libraries
has prompted questions about their purpose as well as
provenance. Colin Charles posted that some of these would be answered in the very near
future. I have a couple of specific questions about the
MariaDB JDBC driver, which I hope will be addressed at that time.
1.) What is really in the MariaDB JDBC driver and how
exactly does it differ from the drizzle JDBC
driver? What, if any, relation is there to Connector/J
code? There is a …
