In this post, we’ll examine why in an initial flushing analysis we find that Performance Schema data is incomplete.

Having shown the performance impact of Percona Server 5.7 patches, we can now discuss their technical reasoning and details. Let’s revisit the MySQL 5.7.11 performance schema synch wait graph from the previous post, for the case of unlimited InnoDB concurrency:

First of all, this graph is a little “nicer” than reality, which limits its diagnostic value. There are two reasons for this. The first one is that page cleaner worker threads are invisible to Performance Schema (see bug 79894). This alone …

As promised, here are my slides from Percona Live Conference in US, Apr.2016 :

• MySQL 5.7 Performance & Scalability Benchmarks (PDF)
• MySQL 5.7 Demystified Tuning (PDF)

Feel free to ask any questions or details you're needing, etc..

Also, not really related to MySQL, but as I was asked so many times about "how did you manage to project your slides from Mac, but drive it an annotate via iPad?" - here is a short HOWTO:

• you need to have Keynote app installed on both your Mac and iPad
• you create your own WiFi Network on your Mac (MenuBar->WiFi->Create Network...)

In this blog post, we’ll discuss some of the best practices for configuring optimal MySQL memory usage.

Correctly configuring the use of available memory resources is one of the most important things you have to get right with MySQL for optimal performance and stability. As of MySQL 5.7, the default configuration uses a very limited amount of memory – leaving defaults is one of the worst things you can do. But configuring it incorrectly can result in even worse performance (or even crashes).

The first rule of configuring MySQL memory usage is you never want your MySQL to cause the operating system to swap. Even minor swapping activity can dramatically reduce MySQL performance. Note the keyword “activity” here. It is fine to have some used space in your swap file, as there are …

At the 2016 Open Source Conference in Rome, held a few weeks ago, MariaDB was present along with many of the most relevant players in the Open Source community. This included the Italian Public Administration. They are required by law to give preference to free software and open source software. The goal of the Italian Open Source Observatory is to promote the use of open source software in Italian public administrations. They monitor and collect information on cases of open source adoption and best practices related to open technology usage within institutions.

Our focus at the conference this year was in particular on the new important MariaDB security features. They're part of our open source offering starting with the release of MariaDB 10.1. It's extremely important that these features are accessible to all MariaDB users. However, it's very relevant for the Italian Public Administration …

I have been considering a few things that one needs follow, do and have in their projects and applications and I came up with the below list:

1. Object Oriented Techniques and practices
2. Use of Interface Concept
3. TDD (Test Driven Development) based development both on the server and client side
4. Source code management tool like GIT
5. Language specific package management tool for managing dependencies. For example: Composer for PHP
6. Continuous Integration tool
7. Automated testing

There are many more, I might be missing. Please let me know in comments. :)
