- Oct 23, 2026 Quorum Intersection: Why R + W > N Is Necessary but Not Sufficient What the quorum inequalities actually prove about read-write overlap, why they say nothing about the newest value, and where per-key quorums break down across a cluster. databases
- Mar 21, 2026 Fencing and Quorum in Automated Failover Why a new primary must be able to prove the old one cannot write, how leases fail when a machine is paused rather than dead, and where quorum buys safety more cheaply. devops
- Oct 9, 2025 Where the Commit Returns: Synchronous and Asynchronous Replication Boundaries What a commit acknowledgement actually guarantees at each replication mode, how quorum commits move the durability boundary, and why a synchronous replica becomes a latency dependency. databases
- Mar 25, 2025 Quorum Intersection and Why R + W Must Exceed N The arithmetic that guarantees a read sees the latest write, how sloppy quorums break it, and what read repair has to do to restore the guarantee. filesystems
- Jan 27, 2025 Quorum Placement and the Latency of the Second-Fastest Replica How the geometry of replica placement decides commit latency for majority quorums, and why adding a distant replica to a three-node group can be free or fatal. cloud infrastructure
- Nov 18, 2024 Leader Election, Leases, and What Quorum Protects Against Why a control plane needs a single active writer, how lease-based election bounds the overlap window, and where the underlying consensus store changes the guarantee. virtualization
- Nov 15, 2024 Read Repair and Hinted Handoff on the Write Path How leaderless stores bring lagging replicas forward without a full scan, why hinted handoff is a temporary buffer rather than a repair, and where each mechanism fails under sustained failure. distributed systems
- Dec 11, 2023 Quorum Intersection and the Arithmetic of Stale Reads Why R + W > N guarantees a read sees the latest acknowledged write, what that inequality does not guarantee, and how sloppy quorums and read-your-writes routing break it. distributed systems
