On Friday (22/11/2013), we hosted webinar covering the new replication features in the MySQL 5.7 DMR as well as in MySQL Labs. You can now view the webinar replay here (http://www.mysql.com/news-and-events/web-seminars/mysql-replication-discover-whats-new/" target="_blank).
It’s a very exciting time for MySQL Replication! MySQL 5.6 contains numerous new replication features and Oracle recently announced…
With today’s announcement of the second MySQL 5.7 Development Milestone Release and a new labs release it’s a very exciting time for MySQL Replication. MySQL 5.6 contained a lot of new content to make replication faster, easier to use and more reliable (Global Transaction Identifiers, Multi-Threaded Slaves, Binary Log Group Commit, Optimized Row Based Replication, Crash Safe Replication, Replication Event Checksums, Time Delayed Replication & Informational Logs) and now we want to improve things even further.
The new DMR has something for[Read more...]
I was rooting through past blog entries and I stumbled accross a draft post on setting up multi-master (update anywhere) asynchronous replication for MySQL Cluster. The post never quite got finished and published and while the material is now 4 years old it may still be helpfull to some and so I’m posting it now. Note that a lot has happened with MySQL Cluster in the last 4 years and in this area, the most notable change has been the Enhanced conflict resolution with MySQL Cluster active-active replication feature introduced in MySQL Cluster 7.2 and if you’re only dealing with a pair of Clusters, that’s your best option as it removed the need for you[Read more...]
On 17th October I’ll be running a hands-on workshop on the various technologies available to provide High Availability using MySQL. The workshop is being held on 17th October (the day before the All Your Base conference) in Oxford (UK). The cost is £250 + VAT and you can register here.
This workshop provides an introduction to what High Availability (HA) is; what technology options are available to achieve it with MySQL and how to actually implement your own HA solutions. The session will be a mixture of presentations,[Read more...]
With the General Availability of the standalone MySQL Utilities it now makes sense to use these to simplify (and optionally automate) your MySQL Replication and High Availability solutions. In light of that, 4 of our MySQL white papers have been updated to reflect the new opportunities:

With the release of MySQL Utilities 1.3.4, the standalone (not bundled with the MySQL WorkBench GUI) package is now Generally Available and fully supported. This post will focus on a very important change (the ability to run as a daemon rather than in a terminal) to the mysqlfailover utility which allows you to build a light-weight HA database solution using MySQL Replication.
For a general overview of MySQL Utilities,[Read more...]
On Thursday, Dr Charles Bell and I will be presenting a webinar on MySQL Utilities; there will be a heavy focus on what you can acheive with them and how you should use them. As well as listening to the presentation, this is a great chance to get your questions answered by the experts (Israel Gomez from the engineering team will also be on-line to help with the questions). As always, the webinar is free but you should register in advance here (http://www.mysql.com/news-and-events/web-seminars/focus-on-mysql-utilities/" target="_blank). If the time isn’t convenient, register anyway and you’ll be sent a link to the replay when[Read more...]
Update – the recording of this webinar is now available here.
This Wednesday (27th March) Mat Keep and I will be presenting a free, live webinar on MySQL 5.6 Replication. You need to register here (http://www.mysql.com/news-and-events/web-seminars/mysql-5-6-replication-enabling-next-generation-of-web-mobile-social-and-cloud-services/" target="_blank) ahead of the webinar – worth doing even if you can’t attend as you’ll then be sent a link to the replay when it’s available. We’ll also have some of the key MySQL replication developers[Read more...]
In my last few posts, I wrote about “How to install MySQL replication using GTID’s” (Part One, Part Two). In this post, I will show you how to install MySQL 5.6 and set up replication between two MySQL servers the “old fashioned way” using the binary log and binary log position.
I am going to create some virtual machines instead of using individual servers. But, you can[Read more...]
Multi-Threaded SlaveMySQL 5.6 has now been declared Generally Available (i.e. suitable for production use). This is a very exciting release from a MySQL replication perspective with some big new features. These include:
In my last two posts, I wrote about setting up replication with MySQL 5.6 using Global Transaction Identifiers. Even when I set up replication “the old-fashioned way“, one thought always enters my mind – did all of the data copy over to the slave? And, even after the master/slave has been running for a while, I am always wondering if the data in the slave matches the master. Or did the change that I made to that table make it over to the slave? It is probably more of a case of paranoia on my part, as[Read more...]
Following our Percona MySQL University event in Raleigh,NC Percona MySQL University comes to South America! We’ll have a Full day FREE MySQL Technical Educational events in Montevideo on February 5th, 2013 and Buenos Aires on February 7th.
I’m very excited to bring these events to MySQL Community in Uruguay and Argentina. This is my first trip to South America and it looks like it is going to be a lot of fun!
With Percona MySQL University events, we focus on MySQL Education for broad group of users. We’ve specially prepared talks that will be interesting for people just[Read more...]
One of my favorite features of MySQL (http://mysql.com) is replication. Replication provides you with the ability to have MySQL automatically copy data from one MySQL instance to another. There are many benefits to using replication, but I just like having an extra copy of my data on another server in case the main server crashes. But if the master crashes, I can then use the MySQL mysqlfailover script to automatically failover from the master to the slave. (see my earlier post – Using the MySQL Script mysqlfailover for Automatic Failover[Read more...]
