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. …

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 …

I’ve had the opportunity to train lots of people on Percona XtraDB Cluster (PXC) over the last few years the product has existed.  This has taken the form of phone calls, emails, blog posts, webinars, and consulting engagements. This doesn’t count all the time I’ve spent grilling Codership on how things actually work.  But it has culminated in the PXC tutorial I have given annually at Percona Live MySQL Conference and Expo in Santa Clara, California for the last two years.  Baron even attended this year and had this say:

“Jay Janssen’s tutorial on Percona …

I have previously written about the new replication protocol that comes with GTIDs in MySQL 5.6. Because of this new replication protocol, you can inadvertently create errant transactions that may turn any failover to a nightmare. Let’s see the problems and the potential solutions.

In short

• Errant transactions may cause all kinds of data corruption/replication errors when failing over.
• Detection of errant transactions can be done with the GTID_SUBSET() and GTID_SUBTRACT() functions.
• If you find an errant transaction on one …

In our previous post, we introduced the MySQL Fabric utility and said we would dig deeper into it. This post is the first part of our test of MySQL Fabric’s High Availability (HA) functionality.

Today, we’ll review MySQL Fabric’s HA concepts, and then walk you through the setup of a 3-node cluster with one Primary and two Secondaries, doing a few basic tests with it. In a second post, we will spend more time generating failure scenarios and documenting how Fabric handles them. (MySQL Fabric is an extensible framework to manage large farms of MySQL servers, with support for high-availability and sharding.)

Before we begin, we recommend you read this post by Oracle’s …

Message brokers are not regularly covered here but are, nonetheless, important web-related technologies. Some time ago, I was asked by one of our customer to review a selection of OSS message brokers and propose a couple of good candidates. The requirements were fairly simple: behave well when there’s a large backlog of messages, be able to create a cluster and in case of the failure of a node in a cluster, try to protect the data but never blocks the publishers even though that might imply data lost. Nothing fancy regarding queues and topics management. I decided to write my findings here, before I forget…

I don’t consider myself a message broker specialist and I spent only about a day or two on each so, I may have done some big mistakes configuration wise. I’ll take the blame if something is misconfigured or not used correctly.

Going to Percona Live and presenting MySQL Fabric gave me the opportunity to meet a lot of people and get a lot of good feedback. I talked to developers from many different companies and got a lot of great feedback that will affect the priorities we make, so to all I spoke to I would like to say a great "Thank you!" for the interesting discussions that we had. Your feedback is very valuable.

It was very interesting to read the comments on MySQL Fabric on MySQL Performance Blog. The article discuss the current version of MySQL Fabric distributed with MySQL Utilities and give …

While built-in replication has been a major cause for MySQL’s wide adoption, official tools to help DBAs manage replication topologies have typically been missing from the picture. The community has produced many good products to fill in this gap, but recently, Oracle has been filling it too with the addition of MySQL Utilities to the mix.

One part of the Utilities that has been generating interest recently is MySQL Fabric, and we will be discussing this project in an upcoming series of blog …

As you saw in the press release, MySQL Fabric 1.4.2 is now released! If you're interested in learning more about MySQL Fabric, there is a session April 3, 2014 11:10–12pm titled Sharding and Scale-out using MySQL Fabric in Ballroom G.

MySQL Fabric is a relatively new project in the MySQL ecosystem and it focuses on building a framework for working with large deployments of MySQL Servers. The architecture of MySQL Fabric is such that it allows extensions to be added and the first two extensions that we added were support for high-availability using High-Availability groups (HA groups) and sharding to manage very large databases. The first version of sharding have hash and range sharding implemented as well as …

I am very pleased to announce a new event in conjunction with the Percona Live MySQL Conference and Expo this year: Open Source Appreciation Day on Monday, March 31st in the Santa Clara Convention Center! We are pleased to announce two separate groups holding events this year under this new umbrella. We are hosting an event called “OpenStack Today” for those interested in learning more about developments in the OpenStack world. CentOS is holding the “CentOS Dojo Santa Clara” …
