#Distributed Systems

A deep systems architecture guide to cloud object storage: how Erasure Coding (Reed-Solomon) slashes storage overhead by 60% compared to 3x replication, Galois Field GF(2^8) matrix arithmetic, bitrot detection, and high-throughput data reconstruction in Ceph and MinIO.

A deep architectural guide to deterministic distributed OLTP: how the Calvin protocol completely eliminates the latency, distributed locking, and abort cascades of Two-Phase Commit (2PC) by ordering transactions before execution using Paxos sequencers and lock-free parallel execution pipelines.

A comprehensive architectural deep dive into distributed locking: why naive Redis SETNX locks fail during GC pauses and clock drift, the Martin Kleppmann vs. Salvatore Sanfilippo Redlock debate, fencing tokens, etcd consensus leases with watch revisions, PostgreSQL advisory locks, and production Go implementations.

A comprehensive architectural guide to stateful distributed stream processing: mastering Event Time vs. Processing Time, Watermark heuristics for out-of-order data, RocksDB state backends, the Chandy-Lamport checkpoint barrier algorithm, and end-to-end Exactly-Once processing with 2PC sinks in Apache Flink and Kafka Streams.

A deep systems engineering breakdown of distributed consensus protocols: the FLP Impossibility Theorem, Replicated State Machines, Raft leader election & log matching safety invariants, Multi-Paxos Phase 1/Phase 2 quorum rounds, joint consensus cluster reconfiguration, and building a mini Raft state machine in Go.
