DERECHO

Derecho is a supercool library for building high performance replicated systems on RDMA network. Today's platforms provide surprisingly little help to developers of high-performance scalable services. To address this, Derecho automates the creation of complexapplication structures in which each member plays a distinct role. Derecho's data plane runs a novel RDMA-based multicast protocol that scales exceptionally well. The Derecho control plane introduces an asynchronous monotonic logic programming model, which is used to implement strong guarantees while providing a substantial performance improvement over today's fastest multicast and Paxos platforms. A novel subgrouping feature allows any single group to be structured into a set of subgroups, or sharded in a regular pattern. These features yield a highly flexible and expressive new programming option for the cloud...
