Today’s blog post diving into the waters of the MySQL buffer pool is a cross-post from Groupon’s engineering blog, and is Part 1 of 2. Thank you to Kyle Oppenheim at Groupon for contributing to this project and post. We’ll be posting Part 2 on Thursday. I’ll be at the Percona Live MySQL Conference and Expo next week in Santa Clara, California so look for me there – I’d love to connect and talk more about MySQL buffer pools or anything else that’s on your mind!
I think it’s worth noting that since January 2012 there was no changes to MHA (0.53). Yoshinori Matsunobu made two releases in December (release notes), one in time for my Percona Live London 2012 talk. Thanks Yoshi! Totally download MHA 0.55 which is still be actively developed & used in production at multiple locations.
Unser Kollege Ralf Gebhardt ist dieses Jahr mit einem Vortrag zum Thema ‘Hochverfügbarkeitslösungen für die MySQL Datenbank’ auf der DOAG Konferenz zu hören und zu sehen. Weitere Interessante Themen sind z.B. ein Vortrag von Coderships Seppo Jaakola zu ‘Galera Cluster - synchronous multi-master replication for MySQL’.
Wir freuen uns auf Ihren Besuch beim MySQL-Stream der DOAG 2012 Konferenz!
As with all new open source software products, updates are a continuous process and we’ve been busy since the launch of the SkySQL™ Cloud Data Suitelast September! Here is a snapshot of the latest developments with our Cloud Data Suite, a collection of software components that provides a highly available database solution in a cloud environment, based on MySQL & MariaDB, deployable in the Amazon Cloud, i.e. AWS.
When SkySQL opened its doors two years ago, we purposely set out with the goal to build trusted and value-for-money services for users of MySQL and MariaDB databases. We focused on offering a quality alternative for those deploying open source systems - and we feel that we have succeeded. Our plan was to build a service business and customer base that will create a strong platform on which to develop our own products in collaboration with key customers. Red Hat is the only other successful start-up that I am aware of having taken a similar approach of first building a successful services business before developing products.
High Availability is one of the hottest topics for MySQL DBAs. As a matter of fact, when we (SkySQL) are called by users and customers, the top two questions for our PS team are:
Since MySQL is the most used online database, these two questions are totally appropriate. Although the two concepts walk together, they should not be confused.
We refer to scalability when we define that a system must sustain a specific workload, measured in different ways – response time, latency, transactions or operations per second to name few, or a combination of them. So, we define the level of scalability we want to achieve and we design a system that can scale to that level.
We refer to high availability when we define[Read more...]
I just wanted to let you all know that MHA for MySQL (Master High Availability Manager and tools for MySQL) version 0.53 has been released.
Yoshinori Matsunobu discusses the release in much more detail here:

1. Use Auto-scaling
Auto-scaling is a unique feature of cloud computing and Amazon's EC2 offering. Setup a load balancer and a couple of webservers for your application as you normally would. Design your webserver based on a template AMI that you'll reuse over and over. Then setup auto-scaling and set thresholds based on the traffic you forecast. When a threshold is passed, AWS will spinup a new instance of your webserver, and roll it into the load balancer pool[Read more...]
Today, SkySQL announced a partnership with Yoshinori Matsunobu, an Oracle ACE Director and the creator of the newly announced MySQL Master High Availability Manager and Tools (MySQL MHA) for automating MySQL master failover. With this partnership, SkySQL will be the first MySQL database commercial services company to provide technical support, professional services, and training, for MySQL MHA.
