FlowSupervisor

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>

Start with the default Kafka client resource policy.

§Errors

Returns an error when configuration validation, metadata discovery, or worker startup fails.

Source

pub async fn run_with_policy( config: ReplicatorConfig, client_resource_policy: ClientResourcePolicy, ) -> 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 this method lists the topics of the source cluster and filters them by the topic selector of the flow. It excludes already-remote topics, which is the default-naming loop guard, and Kafka and 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 run_with_runtime_policy( config: ReplicatorConfig, client_resource_policy: ClientResourcePolicy, runtime_policy: ReplicatorRuntimePolicy, ) -> Result<Self>

Start using explicit process runtime and topic policy.

§Errors

Returns an error when config validation, discovery, or worker startup fails.

Source

pub async fn shutdown(self)

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

Source

pub async fn crash(self)

Abort the supervisor and its owned workers without draining them.
