Answer
StatefulSets require ordered Pod creation; fast scaling causes readiness delays.
Quick Answer
StatefulSets create and scale Pods sequentially (app-0, then app-1, then app-2) and each Pod must be Running and Ready before the next starts. Scaling quickly means you're waiting for each Pod to initialize, connect to peers, and join the cluster (for distributed DBs, this is critical). Scaling too fast can cause split-brain or replication lag.
