I have a new blog post on blog.booking.com describing MariaDB 10.1 Optimistic Parallel Replication (with benchmark results):

Percona Live Amsterdam is in 3 weeks, and on the evening of the second day of the conference (Tuesday October 4th 2016), there is the traditional Community Dinner.

As last year, Booking.com is hosting the event and as last year, canal boats will bring attendees from the conference venue to Booking.com headquarters.

This event involves some planning: Percona needs to arrange for canal boats and

In a few days, I will be flying to San Francisco and then making my way to Santa Clara to attend the Percona Live Conference.  On the last day of the conference (Thursday), I will speak about MySQL Parallel Replication.  I hope to see you there and I will he happy to answer questions you might have (on this subject and others):

Thursday at 12:50 pm: MySQL Parallel Replication: inventory,

Percona Live is moving from London to Amsterdam this year and the event is also expanding to three full days. Percona Live Europe 2015, September 21-23, will be at the Mövenpick Hotel Amsterdam City Centre. The call for speakers and Super Saver registration are now open. Hurry though because the deadline for submitting a speaking proposal is June 21st and Super Saver registration ends July 5th!

This year’s conference will feature one day of tutorials and two days of keynote talks and breakout …

Ever since MySQL replication has existed, people have dreamed of a good solution to automatically split read from write operations, sending the writes to the MySQL master and load balancing the reads over a set of MySQL slaves. While if at first it seems easy to solve, the reality is far more complex.

First, the tool needs to make sure it parses and analyses correctly all the forms of SQL MySQL supports in order to sort writes from reads, something that is not as easy as it seems. Second, it needs to take into account if a session is in a transaction or not.

While in a transaction, the default transaction isolation level in InnoDB, Repeatable-read, and the MVCC framework insure that you’ll get a consistent view for the duration of the transaction. That means all statements executed inside a transaction must run on the master but, when the transaction commits or rollbacks, the following select statements on the session can be again …

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 …
