pub struct MigrationExecutor { /* private fields */ }Expand description
Executes a vShard migration through the 3-phase protocol.
Coordinates between MultiRaft (for Raft membership + proposal), RoutingTable (for vShard ownership), and the transport layer (for data transfer).
Implementations§
Source§impl MigrationExecutor
impl MigrationExecutor
pub fn new( multi_raft: Arc<Mutex<MultiRaft>>, routing: Arc<RwLock<RoutingTable>>, topology: Arc<RwLock<ClusterTopology>>, transport: Arc<NexarTransport>, ) -> Self
Sourcepub fn ghost_table(&self) -> &Arc<Mutex<GhostTable>>
pub fn ghost_table(&self) -> &Arc<Mutex<GhostTable>>
Access the ghost table (for scatter-gather resolution).
Sourcepub async fn execute(&self, req: MigrationRequest) -> Result<MigrationResult>
pub async fn execute(&self, req: MigrationRequest) -> Result<MigrationResult>
Execute a full 3-phase migration.
This must be called on the source node (the current leader for the vShard’s group).
