Daniel's Distributed Database (DDB)

Overview

This is not an officially supported Google product.

This is code for my learning project Writing A Distributed Database. The project is meant to solidify my understanding of distributed databases, and is by no means production ready.

Those looking for production-quality code should probably look to projects like etcd instead.
