New Options for MySQL High Availability

Data is the currency of today’s web, mobile, social, enterprise and cloud applications. Ensuring data is always available is a top priority for any organization – minutes of downtime will result in significant loss of revenue and reputation.

There is not a “one size fits all” approach to delivering High Availability (HA). Unique application attributes, business requirements, operational capabilities and legacy infrastructure can all influence HA technology selection. And then technology is only one element in delivering HA – “People and Processes” are just as critical as the technology itself.

For this reason, MySQL Enterprise Edition is available supporting a range of HA solutions, fully certified and supported by Oracle. MySQL Enterprise HA is …

Slides of my HOL on MySQL Cluster

Hi!

Thanks everyone who attended my hands-on lab on MySQL Cluster at MySQL Connect last Saturday.

The following are the links for the slides, the HOL instructions, and the code examples.

I'll try to summarize my HOL below.


Aim of the HOL was to help attendees to familiarize with MySQL Cluster. In particular, by learning:

  1. the basics of MySQL Cluster Architecture
  2. the basics of MySQL Cluster Configuration and Administration
  3. how to start a new Cluster for evaluation purposes and how to connect to it

We started by …

Saturday at MySQL Connect

The first day of the first MySQL Connect conference is done.  It's been a busy day!  Many attendees are interested in the new MySQL Server 5.6 release, but of course MySQL Cluster is the main draw here.  After a session from Oracle on the new features in 7.2, and early access features in 7.3, I attended Santo Leto's MySQL Cluster 'hands on lab'.  Despite having started more clusters than most, it felt like a new and exciting experience installing and running my cluster alongside everyone else.  The lab machines had some networking issues, but with Santo's help we seamlessly failed-over to some downloads he'd prepared earlier - very professional!

Afterwards it was my turn to talk on the subject of MySQL Cluster performance.  The quality of the questions was impressive - there seems to be a very capable crowd in San Francisco this …

Tutorial: Getting Started with the NoSQL JavaScript / Node.js API for MySQL Cluster

Tutorial authored by Craig Russell and JD Duncan 

The MySQL Cluster team are working on a new NoSQL JavaScript connector for MySQL. The objectives are simplicity and high performance for JavaScript users:

- allows end-to-end JavaScript development, from the browser to the server and now to the world's most popular open source database

- native "NoSQL" access to the storage layer without going first through SQL transformations and parsing.

Node.js is a complete web platform built around JavaScript designed to deliver millions of client connections on commodity hardware. With the MySQL NoSQL Connector for JavaScript, Node.js users can easily add data access and persistence to their web, cloud, social and mobile applications.

While the initial implementation is designed to plug and play with Node.js, the actual implementation doesn't depend heavily on Node, potentially enabling wider platform support …

Getting Started with MySQL Cluster, Hands-on Lab, Next Saturday, MySQL Connect

Hi!

I'm speaking at MySQL Connect next Saturday, Sep. 29. My Session is a hands-on lab (HOL) on MySQL Cluster.

If you are interested in familiarize a bit with MySQL Cluster this is definitely a session for you.


I will start by briefly introducing MySQL Cluster and its architecture. Then I will guide you through the needed steps to install a local MySQL Cluster, connect to it (using the command line), monitor its logs, and safe shutdown it.

We will hence have a chance to see which are the most common commands using in MySQL Cluster administration (e.g. Cluster backup) as well as the most common operations (e.g. online datanode …

Automated MySQL Master Failover

After the GitHub MySQL Failover incident a lot of blogs/people have explained that fully automated failover might not be the most optimal solution.

Fully automated failover is indeed dangerous, and should  be avoided if possible. But a complete manual failover is also dangerous. A fully automated manually triggered failover is probably a better solution.

A synchronous replication solution is also not a complete solution. A split-brain situation is a good example of a failure which could happen. Of course most clusters have all kinds of safe guard to prevent that, but unfortunately also safe guards can fail.

Every failover/cluster should be considered broken unless:

  1. You've tested the failover scripts and procedures
  2. You've tested the failover scripts and procedures under normal load
  3. You've tested the failover scripts and procedures under high load
