Multi master topologies blues

Tungsten Replicator is a powerful replication engine that, in addition to providing the same features as MySQL Replication, can also create several topologies, such as

  • all-masters: every master in the deployment is a master, and all nodes are connected point-to-point, so that there is no single point of failure (SPOF).
  • fan-in: Several masters can replicate into a single slave;
  • star: It’s an all-masters topology, where one node acts as hub which simplifies the deployment at the price of creating a SPOF.

Welcome Tungsten Replicator 2.1.0!

Overview

First off, the important news. Tungsten Replicator 2.1.0 was released today.
You can download it and give it a try right now.


Second, I would say that I am quite surprised at how much we have done in this release. The previous release (2.0.7) was in February, which is just a few months ago, and yet it looks like ages when I see the list of improvements, new features and bug …

Installing and administering Tungsten Replicator - Part 2 : advanced

Switching roles

To get a taste of the power of Tungsten Replicator, we will show how to switch roles. This is a controlled operation (as opposed to fail-over), where we can decide when to switch and which nodes are involved.

In our topology, host1 is the master, and we have three slaves. We can either ask for a switch and let the script select the first available slave, or tell the script which slave should be promoted. The script will show us the steps needed to perform the operation.

IMPORTANT! Please note that this operation is not risk free. Tungsten replicator is a simple replication system, not a complete …

Do we need a MySQL Cookbook?
+2 Vote Up -2Vote Down

The blog title says it all: Do we need a MySQL Cookbook? I tend to think so.

This seems to be something that is missing with current MySQL documentation. There is lots of information available but finding the appropriate bit can be quite tedious and it often requires looking in multiple places.

A lot of other software has such books, but for some reason MySQL seems to be missing one.

A recent example comes from a “documentation feature request” I posted today: http://bugs.mysql.com/bug.php?id=68171. MySQL 5.6 provides a way to “move InnoDB tables” from one …

On Monday afternoon, Neal Armitage and I will be speaking at Percona Live in London. It will be a three hours tutorial about Tungsten replicator.

The contents of this tutorial are mostly new. We have released recently a new and easier way of installing different topologies, in the shape of cookbook scripts, which are distributed with the replicator tarball.

Using this cookbook, any user can simply install multiple topologies, from the simple master/slave to all-masters, fan-in, and star.

There are recipes for showing the replication cluster, …

I have been asked many times to provide an easy way of deploying fan-in and star schema replication schemas. So far, I have been delayed by more pressing duties.

Now the time has come. Since we are about to release a new version of Tungsten Replicator, I made the effort of putting together the steps for an easy deployment.

Recipes

The package (with downloads and svn code available at Tungsten-Replicator Toolbox) includes some juicy goodies. There are recipes to install.

Quick recipes for database cluster building
+4 Vote Up -0Vote Down

One lesson learned in more than two decades working in this industry is that most of the IT professionals are impatient, want to achieve results immediately, and, most importantly, they don't read documentation. Much as the average geek is happy to answer many requests with a dismissive RTFM, the same geeks are not as diligent when it comes to learning about new or updated technologies. For this reason, there is a kind of documentation that is very much appreciated by busy and impatient professionals: cookbooks. And I am not talking about food. Geeks are not known for being cooks …

High Availability MySQL Cookbook
Employee +2 Vote Up -0Vote Down

MySQL is an easy database to get running initially but it can be tricky to run in demanding environments. High Availability MySQL Cookbook is a relatively thin book packed with information.

The first four chapters are on the care and feeding of a MySQL 7.x Cluster. It starts simply with an initial configuration, covers backups & replication, covers user defined partitioning, and covers troubleshooting node failures. The examples are short, to the point, and devoid of any unneeded filler.

Next come chapters on replication …
