System Design - How Paxos Consensus Works
How Paxos distributed consensus works: the protocol phases, roles (proposer, acceptor, learner), Multi-Paxos optimization, comparison with Raft, and real-world implementations in Google Chubby, Apache ZooKeeper, and Spanner.
-
System Design - How Gossip Protocols Work
How gossip protocols propagate information across distributed systems: epidemic dissemination, SWIM failure detection, push/pull/push-pull strategies, convergence analysis, and real-world implementations in Cassandra, Consul, and Redis Cluster.
-
System Design - How Coroutines and Async/Await Work Under the Hood
How coroutines power async/await: the difference between stackful and stackless coroutines, how Python transforms async functions into state machines, how Go's goroutines use stack-copying, and how the event loop ties it all together.
-
System Design - How HTTP/2 Multiplexing and Flow Control Works
How HTTP/2 multiplexing works: binary framing, streams, flow control, HPACK header compression, and server push — with ASCII diagrams and source code references from the Go net/http2 implementation.
-
System Design - How Circuit Breakers Work in Distributed Systems
How circuit breakers protect distributed systems from cascading failures: state machine design, failure detection, recovery probing, and a source code walkthrough of real implementations.
-
System Design - How Copy-on-Write (COW) Works
How Copy-on-Write works across operating systems, databases, and filesystems: the core mechanism behind fork(), Redis snapshots, LMDB reads, B-tree databases, and modern filesystems like Btrfs and ZFS.
