Written by Marco Tusa   


As most of us know, we will have the chance to attend to the MySQL conference in April (from 18 to 21).

For the ones like me that had being there from long, this is a moment of reunion with colleagues and friend. It is also a moment of confrontation and sharing.

In the years this conference had be the moment for the ones surfing the MySQL sea in which things can be put on the table and discuss. Very few matter if it was call MySQL conference or, as it is now Percona Live. What matter is the spirit with which the people participate, and the desire to share.

One of the important aspects was and is, to be able to learn from others experience, innovation and experimentations.

The past year had be a very difficult for me, thankfully only work wise, but I had also be able to be in some interesting exercises, that had allow me to come with a list of proposal that I consider quite interesting, some more some less as usual, depending from the angle you perform your work.

Anyhow given this year Percona had invite the community to express an opinion on the submissions, I decide to share mine and explain a bit each of them.


Here we go:

The first element is a tutorial on Performance schema. I know that a lot of people are talking about it, presenting in various way the usage of it, and some of the presentations are really really good. So why I should spend time to prepare a tutorial, and why anyone should attend?
My answer is simple, because I am approaching it from a different angle. Most of the presentations look to it as something isolated, auto reference to MySQL space. I am looking to it as part of a larger design and vision, connecting Performance schema to the USE methodology (see other proposal about it).

What I want to achieve during the tutorial is not only to provide instruction on how to access PS or what is there, but how to contextualize the information in the context of the Server(s) behavior.

Here the tutorial title and link for you to vote :

Learn how to use Performance Schema in MySQL 5.7 the basics and not only.





The next one is a presentation that is linked to an article I wrote about the cloud, Galera, Aurora and other solutions.

If you had missed it I suggest you to read it (http://www.tusacentral.net/joomla/index.php/mysql-blogs/175-aws-aurora-benchmarking-blast-or-splash.html).

I had a lot of feedback about that article, from colleagues and from Amazon as well. Given the topic, and given the active evolution that a new product like Aurora is subject to, numbers and conclusion may change in short time.

As such I had plan to perform additional testing during the year (2016), collecting data and present results in articles and presentations.

As mentioned I had a very productive conversation with Amazon about Aurora, and given we all love to have new productive platform, able to perform at the best, I will be more than happy to run those tests with them to help them identify bottlenecks and possible solutions. As usual I will maintain my independence, transparence and impartiality, such that everyone can validate my numbers, and let us see what it will be.

Comparing synchronous replication solutions in the cloud





I cannot say or count at how many presentations I had attended, talking about Performance, and how to analyze, check or improve it. Most focus on this or that aspect of the specific storage engine, or the new feature deliver in the X MySQL release.
But so far I had NOT attend to a presentation that would help me in define a methodology, an organic approach that I can use and reuse for such analysis.

As such I decide to do two things, first was to write an extensive document to be used by my teams in my ex-company (Pythian), something like an endowment for them to follow and relay on to do what is needed to perform a good performance review.

Second to start to talk about it and present the approach. What is important to understand, is that I am not inventing anything new, but using what had be already well defined and apply to the MySQL world.

In short I will present the USE methodology (utilization, saturation, and errors), should be used early in a performance investigation, to identify systemic bottlenecks.
USE can be summarized this way, for every resource, check utilization, saturation, and errors.

My presentation will explain the USE methodology, and how it can help any administrator during the analysis of performance issues. It will also extend the approach for the MySQL specifics, taking advantage of Performance Schema instruments.

The USE Method and how to boost the way you perform performance tuning on your (MySQL) environment





When MySQL 5.6 comes out, I had cover with articles and presentations how to use at the best the new features related to table space managements. Covering how use the features that allow an administrator to play with them, and what kind of issues he may encounter.

You can review them here:




Old presentation here:


My next presentation is an update to it; I will also release articles about this topic during the next year, with more instructions and details for DBA to follow, also covering General table space and compression.

MySQL 5.7 Tablespace management and optimization





Finally I had submitted a proposal for a topic that I personally love, which is related to Java development.

Despite most nasty, and often erroneous, comments, Java is not only a very powerful programming language, but also it is used so often and in so many ways that you can easily state that every day you use several applications develop using it.

What I had often found, and what I had fight against, is the very misuse of several abstraction layers, that developers often use, without understanding what they are doing.

Unfortunately this is a cultural issue that had be push and reinforce in years mostly by bad developers, who do not get how important is keep in mind a very basic concept: “Scaling scenario and huge data, are not present in your laptop”.

The basic meaning is, that whenever you develop code, you need to think to the big numbers, not if that functionality works now, but if it will work on a deployment of 200 application servers, and how it will impact the data layer while scaling.

I will produce a series of articles about this in the future, but the first step is to explain how use and how to use correctly one of the most powerful tool we have at the moment, the MySQL Java connector.

Too often I had see application relay on crazy solutions, or even crazier customize code; ignoring what is already available, able to provide quite efficient out of the box  solution.

This presentation, that you need to see as a first step, has the scope to start a journey, in which we will free good developers, able to think and plan application for the future, from the dumb approach often used by dull abstraction tools.

Empower your application with sophisticate High Availability features using MySQL Connector/j





I had wait a bit before asking you to vote, this because I want to explain why I had submitted what I had submit.

I was also collecting information, comments and feedback about few topics; to be sure I could provide the time to my submission.

What I would like now, is have YOU spend few minutes and think if any of the topic I had describe above may be of your interest.

If so please follow the link and vote for the presentation, if not do not worry I am not tracing your IP and I am NOT going to send you some Italian Friends to convince you to vote for me.

Thanks in advance anyhow!!!


Stay tuned!
