On the road again - FOSSAsia

On the road again - FOSSAsia

It has been a few busy months until now. I have moved from Italy to Thailand, and the move has been my first priority, keeping me from attending FOSDEM and interacting with social media. Now I start catching my breath, and looking around for new events to attend. But before I get into this, let’s make a few things clear:

  • I am still working for Continuent. Actually, it’s because of my company flexibility that I could move to a different country (a different continent, 6 time zones away) without much trouble. Thanks, Continuent! (BTW: Continuent is hiring! )
  • I am still involved with MySQL activities, events, and community matters. I just happen to be in a different time zone, where direct talk with people in Europe and …

MySQL Community Awards 2014: Call for Nominations!

The 2014 MySQL Community Awards event will take place, as usual, in Santa Clara, April 2014, during the Percona Live MySQL Conference & Expo (currently scheduled at Thursday, April 3rd 2014).

The MySQL Community Awards is a community based initiative. The idea is to publicly recognize contributors to the MySQL ecosystem. The entire process of discussing, voting and awarding is controlled by an independent group of community members, typically based of past winners or their representatives, as well as known contributors.

It is a self-appointed, self-declared, self-making-up-the-rules-as-it-goes committee. It is also very aware of the importance of the community; a no-nonsense, non-political, adhering to tradition, self criticizing committee.

The Call for Nominations is open. We are seeking the …

MaxScale, ProxySQL and MySQL Proxy

At FOSDEM 2014 ProxySQL and MaxScale were both presented. Both are proxy that can help build sophisticated MariaDB/MySQL architectures. But currently what is the most used proxy with MySQL? It is HAproxy. HAproxy is a level 4 proxy that has no knowledge of the MySQL protocol. Being low level makes it very fast but it [...]

SF MySQL Meetup Presentation: Changes in MySQL 5.7

Last Wednesday, I spoke at the San Francisco MySQL Meetup on the topic of changes coming in MySQL 5.7 (and later).  We actually went through two different slide decks; the first on features being considered for deprecation in MySQL 5.7 (or later), and the second set providing a brief overview of the new features and benefits already introduced in MySQL 5.7 via the development milestone releases (DMRs) published to date.  A big thanks to the entire SF Meetup group, and in particular the organizers (Erin, Mike and Darren), for having me.  The event was streamed and recorded, and you can view the full presentation on YouTube.  The slide deck can be found here.

The discussion around proposed deprecation was good, and this blog serves to document my own notes about what …

Proposal to enable sql mode ONLY_FULL_GROUP_BY by default

We are considering enabling the SQL mode ONLY_FULL_GROUP_BY by default in MySQL 5.7. Here is a quick example to demonstrate how this change will impact you:

Sample Data:

CREATE TABLE invoice_line_items (id INT NOT NULL PRIMARY KEY auto_increment, 
invoice_id INT NOT NULL,
description varchar(100)
);

INSERT INTO invoice_line_items VALUES 
 (NULL, 1, 'New socks'),
 (NULL, 1, 'A hat'),
 (NULL, 2, 'Shoes'),
 (NULL, 2, 'T shirt'),
 (NULL, 3, 'Tie');

Default behaviour in MySQL 5.6 and below:

mysql> SELECT id, invoice_id, description 
FROM invoice_line_items GROUP BY invoice_id;
+----+------------+-------------+
| id | invoice_id | description |
+----+------------+-------------+
|  1 |          1 | New socks   |
|  3 |          2 | Shoes       |
|  5 |          3 | Tie         |
+----+------------+-------------+
3 rows in set (0.00 sec)

Proposed default behaviour in MySQL 5.7:

mysql> SELECT id, …

Spring cleaning MySQL bugs

The MySQL team has been busy fixing bugs and sorting through older bugs. To give you a couple of recent stats:

  • Norvald blogged about 14 bugs fixed at the request of Linux Distributions.
  • Tomas Ulin’s keynote at Percona Live mentioned 1991 Bugs Fixed in 5.6, with 3763 Bugs Fixed in Total Since MySQL 5.5 GA

As part of our spring cleaning efforts, we have also decided to retire the bug status to be fixed later. That is to say that:

  • Some bugs that were marked as to be fixed later have actually been fixed. Keeping a status of items that won’t be fixed for now has proven difficult to diligently maintain as accurate.
  • We want to prevent a half-way state …

Percona Live 2014 schedule released; BoF and Lightning Talks Call for Papers continues

The complete tutorial & session schedule for Percona Live MySQL Conference & Expo 2014 is released. This schedule offers both a sense of achievement as well as a sense of regret; for I believe the schedule is very good, and yet some good proposals had to be left out.

This is an inevitable result of a conference that is popular and receives far more proposals than can fit within the time frames. This conference offers 96 session slots and 16 3-hour tutorial slots. We got well over 300 proposals -- I'm not even sure how to count them -- and they just can't all fit in. My sincere apologies to all those left out. A proposal of mine was just rejected yesterday from another conference; I can sympathize and empathize with all turned down.

As part of our interest in having a diversity of talks and …
