Struct KafkaControl 

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

Materialized control for a Kafka source.

Implementations§

Source§

impl KafkaControl

Source

pub fn metrics(&self) -> KafkaMetrics

Source

pub fn is_draining(&self) -> bool

Source

pub fn drain_and_shutdown(&self, timeout: Duration) -> MqResult<()>

Stops new emission and waits for already emitted offsets to be committed.

The source iterator completes on its next pull once outstanding offsets are drained. This is the Datum equivalent of the Alpakka DrainingControl hook; datum-agent jobs can call this before stopping the materialized graph.

Source

pub fn shutdown_now(&self)

Stops the source without claiming uncommitted offsets.
