Delos is a new low-dependency storage system for control plane applications at the bottom of the Facebook stack. It supports a rich API (transactions, secondary indices, and range queries) and quorum-style guarantees on availability and durability. Delos is not just a storage system; it’s also an extensible platform for building replicated systems. Delos can be easily extended to support new APIs (e.g., queues or namespaces). Delos can also support entirely different ordering subsystems and switch between them on the fly to obtain performance and reliability trade-offs. As a result, new use cases with various APIs or performance requirements can be satisfied via new implementations of specific layers rather than by a wholesale rewrite of the system.
