Fields§

§pid: PartitionId

the partition id with which this consumer is associated

§partition_queue: PartitionQueue<TunnelingClientContext<GlueConsumerContext>>

The underlying Kafka partition queue

Implementations§

source§

impl PartitionConsumer

source

fn new( pid: PartitionId, partition_queue: PartitionQueue<TunnelingClientContext<GlueConsumerContext>>, ) -> Self

Creates a new partition consumer from underlying Kafka consumer

source

fn get_next_message( &self, ) -> Result<Option<(BorrowedMessage<'_>, PartitionId)>, KafkaError>

Returns the next message to process for this partition (if any).

The outer Result represents irrecoverable failures, the inner one can and will be transformed into empty values.

The inner Option represents if there is a message to process.

source

fn pid(&self) -> PartitionId

Return the partition id for this PartitionConsumer
