Percona Live Amsterdam 2015, why bother?

Another fall, another MySQL community conference. What's the point? Haven't we heard it all before? Same old RDBMS, same old problems, same old speakers, same old venue? What can we expect this year's European conference? Well for starters, the venue has been moved from London to Amsterdam so we have a new acronym; PLEU or PLAM or PLNL? You can decide and use it in your #tweets.

If you hid from all the announcements, Percona acquired Tokutek in April 2015. Tokutek are a company invested in both MySQL and MongoDB landscapes through their fractal tree based storage engines. What does this mean? Well this gave birth to a new scope to the traditionally MySQL-focussed event. Amongst the plethora of high profile company representations you'll see MongoDB, Elastic and Couchbase. So if you're seeking a heterogeneous data conference then you should be there. …

Optimizer hints in MySQL 5.7.7 – The missed manual

In version MySQL 5.7.7 Oracle presented a new promising feature: optimizer hints. However it did not publish any documentation about the hints. The only note which I found in the user manual about the hints is:

  • It is now possible to provide hints to the optimizer by including /*+ ... */ comments following the SELECT, INSERT, REPLACE, …

Team Tokutek is proud to join Team Percona!

If you haven’t already heard, on the Tuesday morning of the 2015 Percona Live MySQL Conference and Expo it was announced that Tokutek is now part of the Percona family.  This means TokuDB® for MySQL, and TokuMX™ for MongoDB are Percona products now; and that the Tokutek  team is now part of the Percona team.

Staying ahead of MySQL operational problems at Percona Live

I’ve started my long journey from Florianópolis, Brazil, to Santa Clara, California and I type this words while waiting for a connection flight. Next Wednesday, Daniel Guzmán Burgos and I will be presenting in the Percona Live MySQL Conference and Expo (PLMCE).

I’m so excited with the new MySQL 101 program that has been added to this year’s event! Along the years I’ve been working as a Support Engineer at Percona I’ve heard two very distinct types of comments amongst others from some people, customers and community in general, about PLMCE:

1) That they went and it was awesome but they found it hard to follow as most of the …

InnoDB locks and deadlocks with or without index for different isolation level

Recently, I was working on one of the issue related to locks and deadlocks with InnoDB tables and I found very interesting details about how InnoDB locks and deadlocks works with or without index for different Isolation levels.

Here, I would like to describe a small test case about how SELECT ..FOR UPDATE (with and without limit) behave with INSERT/UPDATE and with READ-COMMITED and REPEATABLE-READ Isolation levels. I’m creating a small table data_col with few records. Initially, this test case was written by Bill Karwin to explain details to customer, but here I have used a bit modified test case.

CREATE TABLE data_col (dataname VARCHAR(10), period INT, expires DATE, host VARCHAR(10));

INSERT INTO data_col VALUES (‘med1′, …

More on (transactional) MySQL metadata locks

Two years ago Ovais Tariq had explained in detail what kinds of problems existed before MySQL introduced metadata locks in 5.5.3 and how these locks help to prevent them. Still, some implications of metadata locking in MySQL remain unclear for users – DBAs and even software developers that target recent MySQL versions. I’ve decided to include a slide or two into the presentation about InnoDB locks and deadlocks I plan to make (with my colleague Nilnandan Joshi) on April 16 at Percona Live 2015.

I decided to do this as …

‘Woz on your mind?’ Share your questions for Steve Wozniak during his Percona Live keynote!

Here’s your chance to get on stage with Woz! Sort of. Apple co-founder and Silicon Valley icon and philanthropist Steve Wozniak will participate in a moderated Q&A on creativity and innovation April 14 during the Percona Live MySQL Conference and Expo in Santa Clara, California.

Woz once said that he never intended to change the world. That was the other Steve, Steve Jobs.

“I didn’t want to start this company,” Woz told the Seattle Times of Apple’s beginnings in a 2006 interview. “My goal wasn’t to make a ton of money. It was to build good computers. I only started the company when I realized I could be an engineer forever.”

What would you ask Woz if given the opportunity?

“Woz, what first sparked your interest in engineering?”
“Hey Woz, how did you come up with …

FoundationDB is acquired by Apple: My thoughts

TechCrunch reported yesterday that Apple has acquired FoundationDB. And while I didn’t see any mention if this news on the FoundationDB website, they do have an announcement saying: “We have made the decision to evolve our company mission and, as of today, we will no longer offer downloads.”

This is an unfortunate development – I have been watching FoundationDB technology for years and was always impressed in terms of its performance and features. I was particularly impressed by their demo at last year’s Percona Live MySQL and Expo. Using their Intel NUC-based Cluster, I remember Ori Herrnstadt showing me how FoundationDB handles single-node …
