Following our events earlier this year in Raleigh, Montevideo, Buenos Aires, Toronto and Portland, we bring Percona University to Washington, D.C. on September 12. This free one-day technical education event will cover many MySQL ecosystem technologies, including: Percona Server, MariaDB, MySQL 5.6, Percona XtraDB Cluster, Tungsten Replicator, Percona XtraBackup, MySQL Cluster and Percona Toolkit. We […]
Good news everyone! I recently presented a webinar: Percona Server 5.6: Enterprise Grade MySQL. It was also recorded so you can watch along or view the slide deck. As with all my talks, I am not simply reading the slides so it really is worth to listen to the audio rather than just glance through […]
Percona XtraDB Cluster (PXC) was released over a year ago and since then there has been tremendous interest and adoption. There’s plenty of talks that explain the fundamentals of PXC, but we’re starting to reach a threshold where it’s easier to find folks with PXC in production and such the need for more advanced talks […]
MySQL can be deployed in several ways, and that means you can choose a tailor-made path that best meets your needs. With simple services or development systems, many people are using a single server with some backups configured, and then simply take the downtime when a restore is needed. As the application evolves, additional requirements […]
I’ve been woefully neglectful of my responsibilities to post regularly about Percona Live MySQL Conference and Expo 2013 (PLCME 2013), but here’s some highlights of what I am planning to attend from the schedule. Read to the very bottom for the chance to win a free full pass to the conference! When picking talks to attend, […]
Thanks to all attendees of the webinar yesterday! If you missed it, you can watch the video recording. Here are some questions that remained unanswered due to time constraints. Q: Are there any technical considerations or best practice tips to have a replicated slave in the cloud, for example on Amazon AWS? Hardware resources are […]
I just realized that we haven’t blogged a list of our sessions at the O’Reilly MySQL Conference and Expo (#mysqlconf) yet. Here is a hopefully complete list.
We have a special Friends of Percona discount code that you can use to get 20% off of registration at the MySQL conference in April: mys11pkb. If you click the image to the left, or this special link, it will pre-fill the code for you when you check out. Read on to see the list […]
You probably saw the Twitter storm over Oracle’s pricing changes and InnoDB in the last few days. The fear about Oracle removing InnoDB from the free version of MySQL was baseless — it was just a misunderstanding. Still, in the years since MySQL has been acquired by Sun, and then by Oracle, many MySQL users […]
Note: This blog post is part 1 of 4 on building our training workshop.
The Percona training workshop will not cover sharding. If you follow our blog, you’ll notice we don’t talk much about the subject; in some cases it makes sense, but in many we’ve seen that it causes architectures to be prematurely complicated.
So let me state it: You don’t want to shard.
Optimize everything else first, and then if performance still isn’t good enough, it’s time to take a very bitter medicine. The reason you need to shard basically comes down to one of these two reasons
