At Twitter, we have gone through many iterations of storage systems as we have coped with tremendous growth. In the process of building these, we have been able to solve some of the core problems related to distributed storage in a general fashion with a framework we wrote named Gizzard. This has allowed us to quickly and safely develop specialized components for the parts of Twitter that can no longer handle the scale at which they are required to operate.

In this talk, I will go over how we got to where we are now, the core principles we have followed to make writing and reasoning about these systems as simple as possible, and how we have benefited from using MySQL as a solid base.

Topics covered:

A set of general distributed systems design principles Application of said principles to a few concrete problems Building off of established technology Coordination among multiple readers/writers Resilient error handling

At the end of this talk, whether or not they use Gizzard, participants will be better equipped to develop their own scalable systems, having seen how certain not necessarily intuitive solutions can help solve many different distributed storage problems.
