I do not build database engines. I build web applications. I see apps with different requirements and different data storage needs.
This is a story about one of those times — why we picked it originally, how we discovered it was wrong, and how we recovered.
It all happened on an open source project called Diaspora. The project Diaspora is a distributed social network with a long history. They sent it out to friends and family, and hoped for the best. But they hit a nerve.
Diaspora was the first Kickstarter project to vastly overrun its goal. The fallout from that was actually how I first heard about the project.
As a result of their Kickstarter success, the guys left school and came out to San Why do you need a business to start writing code.
They ended up in my office. I worked with official clients during the day, then hung out with them after work and contributed code on weekends. They ended up staying at Pivotal for more than two years. By the end of that first summer, though, they already had a minimal but working for some definition implementation of a distributed social network built in Ruby on Rails and backed by MongoDB.
The main technical difference between Diaspora and Facebook is invisible to end users: The Diaspora infrastructure is not located behind a single web address. There are hundreds of independent Diaspora servers. The code is open source, so if you want to, you can stand up your own server. Each server, called a pod, has its own database and its own set of users, and will interoperate with all the other Diaspora pods that each have their own database and set of users.
Pods of different sizes communicate with each other, without a central hub. You can follow other users on your pod, and you can also follow people who are users on other pods.
Your pod is notified over the API. You look at your activity feed and see that post mixed in with posts from the other people you follow.
Comments work the same way. Everyone who has permission to see the post sees all the comments, just as you would expect if everyone were on a single logical server. There are technical and legal advantages to this architecture.
The main technical advantage is fault tolerance. Here is a very important fault tolerant system that every office should have. The system survives, and even expects, network partitioning.
The main legal advantage is server independence. Each pod also sets their own terms of service. On most of them, you can post content without giving up your rights to it, unlike on Facebook. But in other ways it is anything but typical. The internal structure of one Diaspora pod The visual UI is of course how website users interact with Diaspora.
And of course, MongoDB is an atypical choice for data storage. Conceptually, we do think about it as a network — an undirected graph in which we are in the center, and our friends radiate out around us.
