Back in the days when somebody said MySQL, there was only the MySQL. You could pick different versions (4.0, 4.1) but the vendor was the same. This changed around MySQL 5.0/5.1 when Percona decided to release their own flavour of MySQL - Percona Server. A bit later, MariaDB joined with MariaDB 5.1 and the fun (or confusion) increased. What version should I use? What is the difference between MySQL 5.1, Percona Server 5.1 and MariaDB 5.1? Which one is faster? Which one is more stable? Which one has superior functionality? With time, this got worse as more and more changes were introduced in each of flavours. This blog post will be our attempt to summarize the key features that differentiate them. We will also try to give you some suggestions about which flavour may be the best for a given type of project. Let’s get started.

Many organizations have MySQL or MariaDB databases at the core of their business—for processing and storing product sales, collecting information related to services offered, or just providing essential information to customers. As a result, keeping these databases running continuously can be critical for the success of an organization.

There are many components of a database system that a database administrator will need to consider for maintaining high availability. We considered server equipment (e.g., memory) in a previous introductory article. Now let’s look at using multiple servers for your MySQL and MariaDB databases—let’s look at replication.

We are just starting to get into the swing of setting up our new training and webinar schedule. Initially, there will be one Webinar session (typically on a Wednesday) and one training session (on a Tuesday) every week from now. We’ll be covering a variety of different topics at each. Typically our webinars will be about products and features, comparisons to other products, mixed in with product news (new releases, new features) and individual sessions based on what is going on at Continuent and the market in general. Our training, by comparison, is going to be a hands-on, step-by-step sequence covering all of the different areas of our product. So we’ll cover everything from the basics of how the products work, how to deploy them, typical functionality (switching, start/stop, etc), and troubleshooting. All of the sessions are going to be recorded and we’ll produce a suitable archive page so that you can go and view the past sessions. Need a …

Sharing keys, passphrases with applications is problematic, especially with regard to encrypting data. Too often applications are developed where “the keys are left in the door” or at best “under the mat” – hard coded, in a clear text property file… exposed and vulnerable. …

This is the late blog post about 2 recent bug reports
#85969
#85971

The basic idea came after reading -> http://mysqlserverteam.com/the-mysql-8-0-1-milestone-release-is-available/

So the result of test ->
After each restart of MySQL the new undo log files are going to be created + keeping old files.

shahriyar.rzaev@qaserver-06:~/sandboxes/msb_8_0_1/data$ du -hs
6.4G    
# The count of undo files
shahriyar.rzaev@qaserver-06:~/sandboxes/msb_8_0_1/data$ ls | grep undo | wc -l
539

After new restart:

# New count
shahriyar.rzaev@qaserver-06:~/sandboxes/msb_8_0_1/data$ ls | grep undo | wc -l
616

So how to …

If you look into the key elements of replication, then the very basic element is Binary log or binlog. Over the period of time we have made efforts to improve the management of this quintessential element of replication. To keep up with our raising standards and requirements coming from the global MySQL community we have introduced two new features to help you manage your binary logs more efficiently.…
