内容简介:Spring For Apache Kafka 2.0 Milestone 1 发布
Spring for Apache Kafka 2.0 的首个里程碑版本发布了 — Spring For Apache Kafka 2.0.0.M1 。
Spring for Apache Kafka 用于为 Apache Kafka 提供熟悉的 Spring 抽象。
2.0 系列中的重要新功能包括:
-
在
KafkaTemplate
中支持时间戳 -
Seek to beginning/end of topics
-
New threading model facilitated by KIP-62 - now that the consumer client does not rely on
poll()
being called frequently, the threading model is much simpler; avoiding the need for internalpause()
/resume()
processing. Listeners are now always invoked on the consumer thread. This, in turn, has facilitated: -
ConsumerAwareMessageListener
(andBatchConsumerAwareMessageListener
) are provided so that listener implementations can access theConsumer<?, ?>
object to perform operations such aspause()
,resume()
,metrics()
etc. -
@KafkaListener
POJO methods can now be annotated with@SendTo
to send the method result to some other topic.
@KafkaListener(id = "replyingListener", topics = "inTopic") @SendTo("replyTopic") public String replyingListener(String in) { return in.toUpperCase(); }
