Apache Kafka - 构建数据管道 Kafka Connect

比如说，你有一个网站，你想要将用户的数据传输到另一个地方进行分析，那么你可以使用 Kafka Connect 来完成这个任务。 Kafka Connect 的使用非常简单。...Kafka Connect可以很容易地将数据从多个数据源流到Kafka，并将数据从Kafka流到多个目标。Kafka Connect有上百种不同的连接器。...JMS Apache HBase Apache Cassandra InfluxDB Apache Druid 这些连接器可以使Kafka Connect成为一个灵活的、可扩展的数据管道，可以轻松地将数据从各种来源流入...自定义转换器通常需要实现org.apache.kafka.connect.storage.Converter接口，并提供序列化和反序列化方法的实现。...---- Kafka Connect API vs Producer 和 Consumer API Kafka Connect API 正是为了解决数据集成中的常见问题而设计的。
