Guide to building a three‑node Neo4j causal cluster that delivers ACID writes while scaling reads, with verification steps and failure‑mode checks.
Goal: achieve a seamless version upgrade of a three‑node Neo4j causal cluster without noticeable downtime for a small write‑heavy application. Constraint: during a rolling upgrade old and new nodes run different protocol versions, which can increase lock‑contention and trigger the transient TransactionDeadlockDetected error; the application must distinguish
