public interface RaftSystemOperation
extends AllowedDuringPassiveState, ReadonlyOperation

Marker interface for all operations used in Raft system. RaftSystemOperation extends a few interfaces to bring in some extra features:

• AllowedDuringPassiveState: Raft operations are submitted while a node is shutting down to replace shutting down member with a new one.
• ReadonlyOperation: Raft operations are executed on partition threads but not sent to partition owners. To avoid invocations fail with PartitionMigratingException, we mark them as read-only from Hazelcast partitioning system perspective.
