Hi @kspmmitt, Cruise Control relies on Kafka’s built-in partition reassignment APIs, which are safe and atomic. Kafka only starts replicating data to a new broker and does not remove the original replica until the new one is fully in sync. Even if a rebalance were to fail partway, there will be no data corruption or inconsistent state. The Kafka cluster will continue to operate correctly.
