Followup questions to ‘What’s new in Percona XtraDB Cluster 5.6′ webinar

Thanks to all who attended my webinar yesterday.  The slides and recording are available on the webinar’s page.  I was a bit overwhelmed with the amount of questions that came in and I’ll try to answer them the best I can here.

Q: Does Percona XtraDB Cluster support writing to multiple master?

Yes, it does.  However, locks are not held on all nodes while a transaction is in progress, so there is a possibility for conflicts between simultaneous writes on different nodes.  Certification is the process that Galera uses to protect your data integrity, and the problem is pushed back to the application to handle in the form of deadlock errors.   As long as you understand this and the conditions where you may see more deadlocks (and your application can properly handle them), multi-node …

Looking to upgrade to MySQL 5.6? Check out my webinar on Jan 29!

We are nearing the one-year anniversary since MySQL 5.6 went GA – which is typically a good time even for the most conservative users to start thinking about upgrading. At this point there is a fair amount of practical use and experience; many bugs have also been fixed (1991 to be exact according to Morgan Tocker).

We also know that MySQL 5.6 has been used in some very demanding environments on a very large scale, such as at Facebook. We also know from the Facebook team, after kindly sharing their upgrade experiences, that it takes a lot of work to upgrade to MySQL 5.6. That’s where Percona can help!

In my webinar this Wednesday, “ …

Analyzing WordPress MySQL queries with Query Analytics

This blog,, is powered by WordPress, but we never really looked into what kind of queries to MySQL are used by WordPress. So for couple months we ran a Query Analytics (part of Percona Cloud Tools) agent there, and now it is interesting to take a look on queries. Query Analytics uses reports produced by pt-query-digest, but it is quite different as it allows to see trends and dynamics of particular query, in contrast to pt-query-digest, which is just one static report.

Why looking into queries important? I gave an intro in my previous post from this series.

So Query Analytics give the report on the top queries. How to detect which query is “bad”?
One of metrics I am typically looking into is ratio of “Rows …

Drupal and MySQL Performance: Register now for Nov. 13 webinar

Drupal is one of the most popular open source CMS applications available – and it runs primarily on a MySQL backend.  Out of the box, the schema is well tuned and indexed.  However, there are some ways to tweak the default installation to get more out of the system right from start.  Similarly, there is a fair bit of hidden flexibility (especially in the latest version) in terms of database configuration.

In a free MySQL webinar on Wednesday, November 13th at 1pm EST, I’ll go over some of the improvements in Drupal 7 in terms of database connectivity and operation as well as profile the default installation from the database perspective.  I’ll also be covering some of the ways to optimize the default application and detailing some of the ways to benchmark your installation.

The title …

MySQL 5.6 New Replication Features: Webinar followup Q&A

I want to thank all attendees of my webinar, “MySQL 5.6 New Replication Features: Benefits, Challenges and Limitations“. We had questions that I didn’t have the time to answer:

A: Crash-safe replication is already configured for read replicas using MySQL 5.6.

Q: How the relay log purge will manage in case of multiple db’s replication running on multiple threads?

A: Same thing as with single-threaded replication: when all event in a relay log file have been executed, …
