Abstract
The configuration of a distributed storage system with multiple data replicas
typically includes the set of servers and their roles in the replication protocol.
The configuration can usually be changed manually, but in most cases, system
administrators have to determine a good configuration by trial and error. We
describe a new workload-driven optimization framework that dynamically determines
the optimal configuration at run time. Applying the framework to a large-scale
distributed storage system used internally in Google resulted in halving the
operation latency in 17% of the tested databases, and reducing it by more than 90%
in some cases.
