- May 11, 2026 Version Vectors and Conflict Detection in Multi-Writer Replication How per-replica counters encode causal history, why vector comparison identifies concurrency that timestamps hide, and what the vectors cost in metadata and pruning. distributed systems
- Apr 22, 2025 Conflict Resolution When Two Regions Accept Writes Last-writer-wins, version vectors, and application merge: what each guarantees about concurrent cross-region updates, and which invariants each one breaks. cloud infrastructure
- Jan 23, 2025 Optimistic Concurrency and the Conflict Check That Arrives Too Late How version-token conflict detection works in a replicated store, why it cannot prevent a conflicting write, and what the abandoned Bayou and Coda designs revealed about the cost of checking after the fact. computing history
- Jan 18, 2023 Version Vectors and Hybrid Logical Clocks for Mobile Sync Ordering Why wall-clock timestamps cannot order edits made on different devices, how a version vector detects concurrent writes, and what a hybrid logical clock adds without needing agreement on time. mobile computing
