Choosing the right MySQL High Availability Solution – webinar replay

Earlier this week, I presented a webinar on MySQL High Availability options for MySQL – what they are and how to choose the most appropriate one for your application.

The replay of this webinar can now be viewed here or if you just want to look at the charts then scroll down. At the end of this post, I include a summary of the Q&A from the webinar.

How important is your data? Can you afford to lose it? What about just some of it? What would be the impact if you couldn’t access it for a minute, an hour, a day or a week?

Different applications can have very different requirements for High Availability. Some need 100% …

Nuances of MySQL Fabric User GRANTs

MySQL Fabric is a new product and some folks are running into issues when trying to deploy test instances that grow beyond a single server.

The Fabric documentation has an example GRANT statement illustrating the simple localhost use case:

CREATE USER 'fabric'@'localhost' IDENTIFIED BY 'secret';
GRANT ALL ON *.* TO 'fabric'@'localhost';

The example shown above belies the more complex way that Fabric uses the fabric login.

The Fabric config file has 3 sections that deal with user and password values, I will only focus on the [servers] section of the configuration file.  The user and password defined in this section is used by the mysqlfabric utility to connect to managed servers …

Accessing Fabric HA Groups from Java

It's been almost a year now since the initial release of MySQL Fabric. It is maturing and reached a GA state earlier this year as part of MySQL Utilities 1.4. Developers and architects are evaluating it for their applications, learning the capabilities of the system, and providing feedback for future features and usability enhancements. Connector/J has supported Fabric from the very beginning and continues to support the latest features. This blog post is an introductory level guide to using Fabric for high-availability from Java applications. Sharding features and Java APIs will be covered in a later post. The commands shown and feature descriptions are current for Fabric 1.5.1. In addition, Connector/J 5.1.32 and later support only Fabric 1.5 due to communication protocol differences from Fabric 1.4.

High-availability is a core concept in Fabric and is implemented by HA groups. An HA group is a set of servers configured with MySQL …

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 …

MySQL Fabric now Generally Available – Automating High Availability and Sharding for MySQL


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.

Connector/J 5.1.30 is out with Fabric support

Today marks the release of several exciting pieces of software from Oracle. In addition to MySQL server 5.7.4 DMR, MySQL Fabric is out as a release candidate 1.4.2 and Connector/J 5.1.30 has full support. MySQL Fabric is a new way to implement high-availability and scale-out with MySQL server. It provides a way to group sets of servers into high-availability groups with automatic replication configuration. If scale-out is important, sharding can be defined in terms of these high-availability groups.

To use Connector/J with Fabric, you only need to add the jar to your classpath. If you are still using Java 5, you will need to manually load the com.mysql.fabric.jdbc.FabricMySQLDriver class to register the driver. Fabric-aware connections are made with a JDBC URL of the form jdbc:mysql:fabric://host:port/db. Several connection properties are available to influence the behavior of Fabric-aware connections. You can find the documentation for …
