Orca: Flexible Quorums Meet Dynamic Quorums
Summary: Orca combines Raft replication with Flexible Paxos, fixing replication quorums at k+1 under temporally separated failures and dynamically shrinking election quorums as faults are detected. It sustains progress under accumulating crashes, outperforming Raft and FlexiRaft with negligible overhead. (summarized by gpt-5.6-luna on Aug 28 2026)
