Sherpa is Yahoo!'s next-generation structured-record distributed storage service that addresses growing scalability needs of Yahoo!'s properties. Important features of Sherpa include high scalability, elastic growth, a global footprint, and low-latency access from anywhere. One key difference between Sherpa and other distributed database systems is Sherpa's support for different consistency models, allowing the application developer to manage the trade-off between consistency, availability, and performance. In this talk, I will give an overview of the Sherpa architecture and describe how various web serving application can use Sherpa to solve their data storage problems.
