The journey of a request in a Raft-based KV store (from client to commit)
https://www.reddit.com/r/programming/comments/1s9jn4n/the_journey_of_a_request_in_a_raftbased_kv_store/

<!-- SC_OFF -->After implementing the MIT 6.5840 distributed systems labs, I wanted to better understand what actually happens when a client sends a request to a replicated key-value store built on Raft. I wrote a short article where I follow the full path of a request:
client → leader → replication → commit → apply → response What surprised me is how quickly this “simple” flow breaks in practice: leader can change mid-request network partitions create stale leaders retries can lead to duplicate execution A lot of the complexity isn’t in Raft itself, but in making the system behave correctly under these conditions. Would be interested in feedback, especially if you’ve built something similar. <!-- SC_ON --> submitted by /u/am0123 (https://www.reddit.com/user/am0123)

You can't scale when you're dead [TigerBeetle video]
https://www.reddit.com/r/programming/comments/1s9o9ue/you_cant_scale_when_youre_dead_tigerbeetle_video/

<!-- SC_OFF -->From Monster Scale Summit ... Scale is about survivability, not just performance: a system that can't stay alive when things break can't scale at all. This talk examines the limits holding back most OLTP systems, traces database architecture through seven stages of survivability, and demonstrates a diagonal scaling approach designed to handle hundreds of billions of transactions. <!-- SC_ON --> submitted by /u/swdevtest (https://www.reddit.com/user/swdevtest)
