Kafka Streams 是用于处理 Kafka Topics 间数据交换目前已知最好的框架,诸如:exactly once semantic、join、stateful 数据处理等功能都是开箱即用的。 但是在 Kafka Streams微服务与 Kafka 集群运维的过程中常常会出现一些合作上的问题,比如:集群管理员不知道哪些 Topics 可以通过应用恢复的(changelog,repartition),哪些一...

首先,先创建一个KafkaStreams实例,其中构造函数的第一个参数用于定义一个topology builder(Streams DSL的KStreamBuilder,或Processor API的TopologyBuilder)。第二个参数是上面提到的StreamsConfig的实例。 import org.apache.kafka.streams.KafkaStreams; import org.apache.kafka.streams.StreamsConfig; import org.apache.ka...
Consumer API 允许一个应用程序去订阅一个或多个 topics,并且处理产生给它们(前面的topics)的记录流。 Streams API 允许一个应用程序去扮演一个stream processor(流化处理器),从一个或多个topics中消费一个输入流,并且产生一个输出流到一个或多个输出的 topics 中,有效转换输入流到输出流。 Connector API 允许建造...

Mirroring of data between Kafka clusters can be done using a utility called MirrorMaker. When it is run, MirrorMaker starts a number of threads that each subscribe to the topics found in a Kafka cluster. Multiple MirrorMaker processes can be run on different machines to get the benefits of ...

Kafka Streams allow you to consume from multiple input topics. While defining a new stage you can specify the topic name on which the pattern should be applied : builder.select("my-stage",Selected.fromTopic("my-topic"))) Demonstration ...
