MySQL Sandbox now with plugins, more tests, instrumentation
Posted by Giuseppe Maxia on Sun 30 May 2010 19:01 UTC

The latest release of MySQL Sandbox, 3.0.12, has integrated plugin installation features, as mentioned in my previous post.
Not only that. This version has also more tests, fixes a couple of bugs, and introduces basic instrumentation. Now each script released with MySQL Sandbox, and every one that the Sandbox itself installs, can leave a trail in a file.


Let's start with the plugin. The documentation has been updated to cover this new feature. And 27 new tests give me some confidence that it …

MySQL Sandbox meets plugins
Posted by Giuseppe Maxia on Mon 24 May 2010 20:32 UTC

I saw it coming.
In the past year I have been working more and more with plugins. The InnoDB plugins, the semi-synchronous replication plugins, the Gearman UDFs, the Spider plugins, and every time I found myself doing a long installation process, with inevitable mistakes.


So I told myself "I wish I had a tool that installed plugins instantly and painlessly, the way MySQL Sandbox installs a server.
There you go. So yesterday I had enough of suffering and have put together an installation script that does a good job of installing several plugins with little or no effort.
OverviewHow does it work? For now, it's a separate script, but it will soon end into SBtool, the Sandbox tool.
Plugins need different operations, and the difficult part is finding a clear way of …

Jeremy's article on MySQL Sandbox in Linux Magazine

Jeremy Zawodny of Craiglist has written a kind article about MySQL Sandbox.
The article, MySQL Sandbox: Treat MySQL Instances like Virtual Machines, is a practical test of MySQL Sandbox with usage examples and warm appreciation.
Thanks, Jeremy!


The article was published in July but I noticed it only today. I guess I should pay more attention to my favorite topics when I travel.

On Friday afternoon, I went to give a presentation about MySQL advanced features at the Sardegna Ricerche technology park. The presentation included a quick introduction to MySQL Sandbox, something that I have been doing for years, and I thought I could do blindfold, if required. However, something didn't go as expected.

Just when I was showing off how easy is it to install a MySQL sandbox from a tarball, I was faced by an unexpected error. The tar application was not among the recognized ones. As soon as I saw the error, I immediately knew what had …

Remote replication setup with Gearman and MySQL Sandbox
Posted by Giuseppe Maxia on Sun 28 Jun 2009 21:15 UTC
Tags:



A few months ago, Brian Aker invited me to have a look at Gearman, saying that I could find interesting combinations with MySQL Proxy. I did not forget, and I kept thinking about interesting ways of using it. The first idea that I managed to apply is not related to Proxy, but to a practical problem that I have been keeping in reserve for years, i.e. installing replication systems from remote, without effort.


After some fiddling around with the alternatives, I convinced myself that Gearman is the way to go. Before I proceed to show what I did, though, perhaps it's useful if I spend a few words about Gearman …

MySQL Sandbox and laziness
Posted by Giuseppe Maxia on Thu 11 Jun 2009 21:58 UTC

Laziness strikes again.
MySQL Sandbox was created with the intent of avoiding repetitive work when creating and using several servers. Turns out that even the current framework, which many say that is really time saving and enhances productivity, was not enough. So my desire for laziness, which is, as everybody should know a chief virtue for a programmer has made me code a shortcut script, which can joggle sandboxes as never before.


Enter the sb script (available in version 3.0.03). Now I can shorten my typing experience with sandboxes quite a lot:


  $ sb 5135
  # same as calling 
  # …

MySQL Sandbox has a dedicated home

MySQL Sandbox is a mature project (recently released version 3.0), and as such I thought that it deserved a dedicated home.
Thus, I went shopping, and I bought a few domains, all pointing to the same place:

MySQL Proxy => proxydb + replication
Posted by Diego Medina on Wed 27 May 2009 11:37 UTC
Tags:

A couple of weeks ago I wrote a lua script to use with the MySQL Proxy that transforms the Proxy into a key=>value lookup dictionary.

But I couldn't just stop there. So I decided to add replication to it :).


The basic idea is that you have one proxy that acts like a master, it can handle all write/read operations. Once it receives a write query, it will send that query to the slave proxy instances, and after the last slave gets the query, the master will return a confirmation to the mysql client.
And of course, you send your read queries to the slave proxy instances.

Show me the code.
It is available on the …
