For October, we are spotlighting Akshitha Sriraman, Assistant Professor, Department of Electrical and Computer Engineering at Carnegie Mellon University (CMU).
For this RFP, we were especially interested in proposals that addressed fundamental challenges that arise in distributed systems operating at a large scale.
Sharding is widely used to scale an application. Despite a decade of effort to build generic sharding frameworks that can...

This paper introduces FlightTracker, a family of APIs and systems which now manage consistency for online access to Facebook’s graph. FlightTracker implicitly provides RYW and can be explicitly used to provide alternative consistency guarantees for special use cases; it enables flexible communication patterns between caches, which we have found important as the number of datacenters increases; it extends the same consistency guarantees to cross-shard indexes and materialized views, allowing us to transparently optimize queries; and it provides a uniform primitive for clients to obtain desired consistency guarantees across a variety of data stores.
We propose virtualizing consensus by virtualizing the shared log API, allowing services to change consensus protocols without downtime. Virtualization splits the logic of...
