the replicas are named zero, one and two rather than randomly, and each one gets its own disk back after a restart.
StatefulSet
Also calledstateful set, ordinal workload
A workload type giving each replica a stable identity, a stable network name and its own persistent volume, and rolling them in order. It exists for software that cares which member it is — databases, brokers, consensus systems — where interchangeable replicas would be wrong. It is markedly harder to operate than a stateless deployment, which is the usual argument for running data stores as a managed service instead.
