pub struct PlacementStateMachine { /* private fields */ }Expand description
A StateMachine that applies placement-layer Raft log entries to the
cluster’s ShardRegistry.
Only ClusterCommand::PlaceSplit, ClusterCommand::PlaceMerge, and
ClusterCommand::PlaceTransfer entries mutate the registry; all other
command types are treated as no-ops so that the same log can carry data- and
membership-layer entries without needing separate partitioning.
