GRADE-DB: Graceful Degradation via Data Types in Byzantine Quorum Systems
Byzantine quorum systems (BQSs) are used to build
fault-tolerant distributed storage services. In choosing a BQS variation, the
protocol model and assumptions of the variation must
be satisfied in the storage systems to tolerate faulty entities. Performance becomes an important reference in choosing variations of BQSs. In general, better fault tolerance will
result in worse performance in a certain usage scenario.
We propose GRADE-DB,
a fault-tolerant distributed storage service supporting
graceful degradation in BQSs. GRADE-DB servers are capable of running as different variations (or types)
of BQSs, and could switch from one to the other without
interrupting storage services.
