FailureDetector
Este conteúdo não está disponível em sua língua ainda.
Defined in: src/cluster/FailureDetector.ts:26
A simple, deterministic failure detector. Every heartbeat bumps the last-seen timestamp for a peer; the cluster periodically asks which peers have fallen past the thresholds. No φ-accrual / variance tracking — just plain elapsed-time limits, which is sufficient for LAN-scale clusters.
