etcd: Distributed Key-Value Store for Configuration
Deep dive into etcd architecture using Raft consensus, watches for reactive configuration, leader election patterns, and Kubernetes integration.
The FLP Impossibility Result
The FLP impossibility theorem proves that no consensus algorithm can guarantee termination in an asynchronous system with even one faulty process.
Google Chubby: The Lock Service That Inspired ZooKeeper
Explore Google Chubby's architecture, lock-based coordination, Paxos integration, cell hierarchy, and its influence on distributed systems design.
Leader Election in Distributed Systems
Leader election is the process of designating a single node as the coordinator among a set of distributed nodes, critical for consensus protocols.
Multi-Paxos
Multi-Paxos extends basic Paxos to achieve consensus on sequences of values, enabling practical replicated state machines for distributed systems and databases.
Paxos Consensus Algorithm
Paxos is a family of consensus algorithms for achieving agreement in distributed systems despite failures, pioneered by Leslie Lamport.
Raft Consensus Algorithm
Raft is a consensus algorithm designed to be understandable, decomposing the problem into leader election, log replication, and safety.
