pub struct DistributedStreamTopology { /* private fields */ }Expand description
Coordinates stream processing across multiple cluster nodes.
Maintains cluster membership, assigns partitions to nodes using consistent hashing, and broadcasts topology change events.
Implementations§
Source§impl DistributedStreamTopology
impl DistributedStreamTopology
Sourcepub fn new(config: TopologyConfig, total_partitions: u32) -> Self
pub fn new(config: TopologyConfig, total_partitions: u32) -> Self
Creates a new topology with the given configuration and partition count.
Sourcepub async fn add_node(&self, node: StreamNode) -> DistributedResult<()>
pub async fn add_node(&self, node: StreamNode) -> DistributedResult<()>
Adds a node to the topology and rebalances all partitions.
Sourcepub async fn remove_node(&self, node_id: &str) -> DistributedResult<()>
pub async fn remove_node(&self, node_id: &str) -> DistributedResult<()>
Removes a node from the topology and reassigns its partitions.
Sourcepub fn route(&self, partition_key: &str) -> DistributedResult<String>
pub fn route(&self, partition_key: &str) -> DistributedResult<String>
Routes a partition key to its responsible node, returning the node ID.
Sourcepub fn stats(&self) -> TopologyStats
pub fn stats(&self) -> TopologyStats
Returns current topology statistics.
Sourcepub fn change_receiver(&self) -> Arc<Mutex<Receiver<TopologyChange>>>
pub fn change_receiver(&self) -> Arc<Mutex<Receiver<TopologyChange>>>
Returns a handle to the topology change receiver.
