On 19th June 2014, Mats Kindahl and I presented a free webinar on why and how you should be using MySQL Fabric to add Sharding (scaling out reads & writes) and High Availability to MySQL. The webinar replay is available here. This blog post includes a transcript of the questions raised during the live webinar together with the responses given – if you’re questions aren’t answered already then please feel free to post them as comments here.

MySQL was proud to return as a sponsor of the Texas Linuxfest last weekend. Over 700 tickets sold and I probably talked to all bu two or three. Luckily I had help from Quality Assurance Guru Jeb Miller and Software Release Manager Hema Sridharan as things got very busy. The crowd was really supportive of us, MySQL, and extremely friendly.

MySQL Fabric was a popular topic of discussion. Evidently playing ‘who has the virtual IP address’ is a big problem for DevOps staffs and Fabric solves that issue. Many in attendance were on the verge of needing to shard their data and liked having a tool to manage the work for them.

And Workbench 6.1 is extremely popular. Me, “Have you seen the latest MySQL Workbench in action?” Attendee, “Yes, I use it all the time and ti has really become awesome in the last year!” Many non-DBAs who have to look after MySQL instances love the admin tools over fat finger on the command line.

MySQL Fabric – High Availability & Automated Sharding for MySQL

MySQL Fabric is built around an extensible and open source framework for managing farms of MySQL Servers. Currently two features have been implemented – High Availability (built on top of MySQL Replication) and scaling out using data sharding. These features can be used in isolation or in combination. MySQL Fabric aware connectors allow transactions and queries to be routed to the correct servers without the need for a proxy node, so operations run as quickly as ever. In this webinar you will learn what MySQL Fabric is, what it can achieve and how it is used – by DBAs, Dev-Ops and developers. You’ll also be exposed to what is happening under the covers. In addition to the presentation, there will be live on-line Q&A with the engineering team. This is a great opportunity to learn about the latest developments directly from the people building them. …

On Thursday (19th June), Mats Kindahl and I will be presenting a free webinar on why and how you should be using MySQL Fabric to add Sharding (scaling out reads & writes) and High Availability to MySQL. This product has only recently gone GA and so this is a good chance to discover it’s for you and to get your questions answered by the people who wrote the software! All you need to do is register for the MySQL Fabric webinar here.

I have been building a CloudFormation template for MySQL Fabric as an experiment to kick the tyres and further my understanding of how it all works.

For those not familiar, CloudFormation is a way of representing a collection of Amazon Cloud resources (a "stack") into a static json file (a "template"). In my previous company, we managed our AWS account almost exclusively via CloudFormation, and there are two key advantages I see with managing resources via templates:

• It allows for all environments to be synchronized (dev/qa/production).
• It allows for very fast disaster recovery (you can very quickly pick up and restore in another region).

CloudFormation is also a great-fit for MySQL Fabric, since it can remove many of the essential bootstrap steps that come with building a distributed system. It took a bit of work, but I …

This is the third post in our MySQL Fabric series. If you missed the previous two, we started with an overall introduction, and then a discussion of MySQL Fabric’s high-availability (HA) features. MySQL Fabric was RC when we started this series, but it went GA recently. You can read the press release here, and see this blog post from Oracle’s Mats Kindahl for more details. In our previous post, we showed a simple HA setup managed with MySQL Fabric, including some basic failure scenarios. …

MySQL Fabric is a distributed framework that has high availability and sharding as targets. It organizes the servers in groups which use the standard MySQL Replication to providing fault-tolerance. Shards are assigned to different groups thus allowing applications to distribute both reads and writes and exploit resilience to failures as well.

Information on groups, servers and shards are stored in a MySQL Instance called state store or backing store. This instance is a repository for all this information and the engine used might be any supported by MySQL, although a transactional engine must be picked to truly provide fault-tolerance. Note though that we have been testing MySQL Fabric with Innodb and currently this the only official engine supported.

Built upon the repository there are several functions that, besides being used to retrieve information from and update the repository, are responsible for the execution of …

As you might have noticed in the press release, we just released MySQL Utilities 1.4.3, containing MySQL Fabric, as a General Availability (GA) release. This concludes the first chapter of the MySQL Fabric story.

It all started with the idea that it should be as easy to manage and setup a distributed deployments with MySQL servers as it is to manage the MySQL servers themselves. We also noted that some of the features that were most interesting were sharding and high-availability. Since we also recognized that every user had different needs and needed to customize the solution, we set of to create a framework that would support sharding and high-availability, but also other solutions.

With the release of 1.4.3, we have a range of features that are now available to the community, and all under an open source license and wrapped in an …

MySQL Fabric is a new framework that automates High Availability (HA) and/or sharding (scaling-out) for MySQL and it has just been declared Generally Available.

This post focuses on MySQL Fabric as a whole – both High Availability and scaling out (sharding). It starts with an introductions to HA and scaling out (by partitioning/sharding data) and how MySQL Fabric achieves it before going on to work through a full example of deploying HA with MySQL Fabric and then adding sharding on top.

MySQL Replication is a well-known approach to providing high-availability and scaling out read-only operations (i.e. transactions) as well. In order to make it easy to exploit this scalability axis, we have extended both Fabric and the connectors' interface so that an application can express its willingness to execute a read-only operation and have its request redirected to the server that is most capable of handling it.

In this post, we are going to describe how we can use Fabric and the connector python to scale out read-only operations. We need to introduce some concepts first though.

Fabric organizes the servers in high-availability groups, uses the standard MySQL Replication to synchronize the servers which can be classified according to its status, mode and weight. The blog post MySQL Fabric …
