Database Challenges and Innovations. Interview with Jim Starkey

“Isn’t it ironic that in 2016 a non-skilled user can find a web page from Google’s untold petabytes of data in millisecond time, but a highly trained SQL expert can’t do the same thing in a relational database one billionth the size?.–Jim Starkey.

I have interviewed Jim Starkey. A database legendJim’s career as an entrepreneur, architect, and innovator spans more than three decades of database history.


Q1. In your opinion, what are the most significant advances in databases in the last few years?

Jim Starkey: I’d have to say the “atom programming model” where a database is layered on a substrate of peer-to-peer replicating distributed objects rather than disk files. The atom programming model enables scalability, redundancy, high availability, and distribution not available in traditional, disk-based database …

Deep dive into MySQL’s innochecksum tool

One of our Percona Support customers recently reported that Percona XtraBackup failed with a page corruption error on an InnoDB table. The customer thought it was a problem or bug in the Percona XtraBackup tool. After investigation we found that an InnoDB page was actually corrupted and a Percona XtraBackup tool caught the error as expected and hence the backup job failed.

I thought this would be an interesting topic and worthy of a blog post. In this article I will describe the innochecksum tool, when and how to use it and what are the possible fixes if an InnoDB table suffers from …

Percona Live MySQL Conference and Expo 2014: Things I’m looking forward to

The Percona Live MySQL Conference and Expo 2014 is just two months away. I’m very excited about this year’s event which continues our tradition of open technical discussions and inviting all parties to the table.

We have a great amount of technical talks from Oracle – I’m especially excited about future-focused talks shedding some light about what to expect in MySQL 5.7 and beyond. This content is best covered by developers actually designing the system and writing the code. We also have great coverage of MySQL alternatives from Percona and MariaDB. You can view the entire program here.

It is great to see well-rounded coverage of many …

MariaDB-related links in November 2013

Another month has come to an end. If you’re looking to be updated on MariaDB content on a regular basis, don’t forget to be on Twitter (@mariadb), Facebook (MariaDB.dbms), or Google Plus (+mariadb).

There was a question on Quora – Is Facebook considering ditching MySQL in favor of MariaDB like Google did? The best answer really comes from Harrison Fisk, so I’ll leave you to it to read. The older link made its way on social media about Wikipedia_$ mv MySQL MariaDB. …

Tab sweep: Google and MariaDB

I just wanted to collect the links of the Google and MariaDB relationship. These were all items in September 2013.

The Register: Google swaps out MySQL, moves to MariaDB – this was largely based on a presentation at SLAC by Jeremy Cole (slides). Same news was picked up by ReadWrite (with a different angle naturally), Google Waves Goodbye To MySQL In Favor Of MariaDB.

If you’re more audio inclined, there was great discussion on the This Week in Google podcast: checkout episode …

Big Data from Space: the “Herschel” telescope.

There are many aspects to coping with change, including changes in requirements, changes in technology, vendor stability, changes in staffing and so on”–Jon Brumfitt. On May 14, 2009, the European Space Agency launched an Arianne 5 rocket [...]

Percona Live MySQL Conference and Expo 2013: It feels like 2007 again

I actually don’t remember exactly whether it was in 2006, 2007 or 2008 — but around that time the MySQL community had one of the greatest MySQL conferences put on by O’Reilly and MySQL. It was a good, stable, predictable time.

Shortly thereafter, the MySQL world saw acquisitions, forks, times of uncertainly, more acquisitions, more forks, rumors (“Oracle is going to kill MySQL and the whole Internet”) and just a lot of drama and politics.

And now, after all this time some 6 or 7 years later, it feels like a MySQL Renaissance. All of the major MySQL players are coming to the Percona Live MySQL Conference and Expo 2013. I am happy to see Oracle’s engineers coming with talks — and now with a great MySQL 5.6 release — and I have great …
