This is a Raft consensus library and distributed consensus engine implemented in Go. It provides the primitives necessary to build fault-tolerant distributed services by implementing a replicated state machine that ensures a group of servers agree on a shared system state through leader election and log replication. The project distinguishes itself through a pluggable architecture for storage backends and snapshot storage, decoupling the consensus logic from physical persistence. It includes specialized mechanisms for leadership transfer, protocol version management to support rolling upgrade

Dieses Projekt ist eine chinesische Übersetzung des ursprünglichen Forschungspapiers, das das Raft-Konsensprotokoll detailliert beschreibt. Es dient als technische Forschungsübersetzung und Leitfaden für Konsensprotokolle und macht die Spezifikationen des Raft-Algorithmus für chinesischsprachige Personen zugänglich. Die Dokumentation deckt die Kernmechanismen verteilter Systeme ab, einschließlich Leader-Wahl, Log-Replikation und Sicherheitsprotokollen. Sie bietet eine detaillierte Erklärung, wie eine einzige Quelle der Wahrheit über mehrere Server hinweg aufrechterhalten wird, um eine fehlertolerante Cluster-Verwaltung zu erreichen. Das Material adressiert verteilte Zustandsmaschinen-Replikation und Log-Management. Es behandelt technische Konzepte wie Heartbeat-gesteuertes Liveness-Tracking, Wahlen mit randomisierten Timeouts, termbasierte Konsistenz-Versionierung und Snapshot-basiertes Log-Compaction.

Raft is a Go library implementing the Raft consensus protocol for coordinating reliable state machine replication across a cluster. It functions as a distributed systems library for building applications that require strongly consistent replicated state, keeping distributed nodes synchronized and fault-tolerant through automated node elections and log distribution. The library conducts periodic node elections using majority votes to designate a single data authority and prevent split-brain conflicts, while distributing deterministic command logs from leaders to follower nodes using a multi-ph

Raft-java is a lightweight Java consensus library and replicated state machine engine designed to synchronize transaction logs and maintain fault-tolerant state across distributed server nodes. The framework relies on a leader-based replication model that routes write operations through a designated coordinator node, executing RPC-driven consensus protocols and automatic leader elections to maintain cluster agreement. The library supports dynamic cluster membership changes, allowing nodes to be added or removed during runtime without downtime through joint consensus configuration entries app

Raft is a portable C programming library that implements the Raft distributed consensus protocol. It serves as a state machine replication engine and coordination primitive for building fault-tolerant distributed applications and clustered systems. The library manages leader election timeouts, heartbeat monitoring, and log replication across peer nodes to maintain consistent state across servers. It handles client write operations, redirects requests from non-leader nodes, processes voting and replication messages, and supports dynamic cluster membership changes through specialized log entri

Async-raft is an asynchronous consensus framework built on Rust for coordinating replicated state machines across distributed nodes.
