FlowSupervisor

crabka_replicator::supervisor

Struct FlowSupervisor 

Source 
pub struct FlowSupervisor { /* private fields */ }
Expand description

Control plane that owns and supervises the per-flow replication workers.

Implementations§

Source§

impl FlowSupervisor

Source

pub async fn run(config: ReplicatorConfig) -> Result<Self>

Validate config, resolve and start one FlowWorker per flow, then spawn a supervision loop that owns the workers and restarts any that enter RuntimeState::Failed.

For each flow the source cluster’s topics are listed and filtered by the flow’s topic selector, excluding already-remote topics (default-naming loop guard) and Kafka/replicator internal topics.

§Errors

Returns ReplicatorError if the config is invalid, a source cluster cannot be reached for topic discovery, a selector fails to compile, or an initial worker fails to build within its retry budget.

Source

pub async fn shutdown(self)

Signal the supervision loop to stop and gracefully shut down all workers.
