Using KafkaTemplate
to Receive
This section covers how to use KafkaTemplate
to receive messages.
Starting with version 2.8, the template has four receive()
methods:
ConsumerRecord<K, V> receive(String topic, int partition, long offset);
ConsumerRecord<K, V> receive(String topic, int partition, long offset, Duration pollTimeout);
ConsumerRecords<K, V> receive(Collection<TopicPartitionOffset> requested);
ConsumerRecords<K, V> receive(Collection<TopicPartitionOffset> requested, Duration pollTimeout);
As you can see, you need to know the partition and offset of the record(s) you need to retrieve; a new Consumer
is created (and closed) for each operation.
With the last two methods, each record is retrieved individually and the results assembled into a ConsumerRecords
object.
When creating the TopicPartitionOffset
s for the request, only positive, absolute offsets are supported.
