Struct fluvio::TopicProducer

source ·
pub struct TopicProducer { /* private fields */ }
Expand description

An interface for producing events to a particular topic

A TopicProducer allows you to send events to the specific topic it was initialized for. Once you have a TopicProducer, you can send events to the topic, choosing which partition each event should be delivered to.

Implementations§

source§

impl TopicProducer

source

pub async fn flush(&self) -> Result<()>

Send all the queued records in the producer batches.

§Example
producer.send("Key", "Value").await?;
producer.flush().await?;
source

pub async fn send( &self, key: impl Into<RecordKey>, value: impl Into<RecordData>, ) -> Result<ProduceOutput>

Sends a key/value record to this producer’s Topic.

The partition that the record will be sent to is derived from the Key.

Depending on the producer configuration, a send call will not send immediately the record to the SPU. Instead, it could add the record to a batch. TopicProducer::flush is used to immediately send all the queued records in the producer batches.

If the batch queue is full, a send call will block until there will be enough space for new batch.

§Example
producer.send("Key", "Value").await?;
source

pub async fn send_all( &self, records: impl IntoIterator<Item = (impl Into<RecordKey>, impl Into<RecordData>)>, ) -> Result<Vec<ProduceOutput>>

source

pub async fn clear_errors(&self)

Clear partition producers errors in order to make partition producers available. This is needed once an error is present in order to send new records again.

source

pub fn metrics(&self) -> Arc<ClientMetrics>

Return a shared instance of ClientMetrics
