This year was my third consecutive Google Summer of Code and I’ve done all three of my GSoCs for the Drizzle community. The first time I worked on refactoring the commandline options processing system using boost::program_options. The second time I worked on a stored procedure interface for Drizzle. This year I got a very interesting project to work on. My mentor, Brian Aker, asked me if I could work on adding Drizzle backend support for OpenStack. I was very thrilled since I’ve been long trying to contribute to the OpenStack community and OpenStack is a community that I’ve admired since its infant days. So, I happily said yes. Brian charted out a plan asking me to try adding a plugin for Collectd which could be used to collect the Drizzle server’s statistics from time to time. As part of this I had to work with libdrizzle. There were not many co! ncrete examples of libdrizzle usage. I somehow managed to write a simple “Hello,World” kind of libdrizzle based C program which I had used as a base to start working on the plugin. But, because of all the relocating and stuff that was happening in my personal life I never got to finish the plugin and it is still left in a half baked state. I will add a blog showing the basic program that I had written using libdrizzle so that people could use it as a base to build on.
I then moved on to modifying devstack to script so that it uses Drizzle as a backend instead of MySQL. Monty Taylor had already told me that all the Drizzle support is already built in as a part of SQLAlchemy and I wouldn’t have to do much. Hence I started to remove all the MySQL related code and adding its equivalent Drizzle code. Diving further in I had noticed that I would have to modify some of the SQLAlchemy library code and some of the code in Nova which I did and got working OpenStack with Drizzle. I will add another blog post covering how I had achieved the backend support as well.
All in all, I had fun working on this project this year and the amount of satisfaction that I got on seeing OpenStack run with Drizzle in the backend is priceless. Ultimately I too have contributed to OpenStack in one form. Now, Drizzle is truely “on the cloud”.
