アトミックデリバリー（Atomic Delivery）
「すべて完了するか、ひとつも行わないか」の仕組み。
Atomic Delivery (or Atomic Multicast) ensures consistency in distributed systems. If a coordinator sends a broadcast to a cluster of nodes, the system guarantees that they will all reach the same state. If even one node fails to receive the message due to a network or hardware failure, the entire operation is rolled back or compensated for, preventing a split-brain scenario.

お店でおもちゃを買う時のように、「お金を払うこと」と「おもちゃをもらうこと」が同時に起きる仕組みです。おもちゃがもらえないならお金も払わないし、お金が払えないならおもちゃももらえません。中途半端な状態にはなりません。
🤓 Expert Deep Dive
Atomic delivery is often implemented via Two-Phase Commit (2PC) or consensus protocols like Paxos and Raft. It requires reliable multicast foundations and a persistent log.
