Kafka MQTT连接器具有多个主题

Question

We are using Kafka-Mqtt connector from Confluent team. Is there any way to publish data from multiple Mqtt topics to multiple Kafka topics with same name as of Mqtt , ie test1 in Mqtt -> test1 in kafka so on. ?

Answer 1

You can run multiple MQTT Source connectors in order to replicate data from distinct topics:

For example,

{
  "config" : {
    "name" : "MqttSourceConnector1",
    "connector.class" : "io.confluent.connect.mqtt.MqttSourceConnector",
    "tasks.max" : "1",
    "mqtt.server.uri" : "< Required Configuration >",
    "mqtt.topics" : "topic_1"
  }
}

and,

  {
      "config" : {
        "name" : "MqttSourceConnector2",
        "connector.class" : "io.confluent.connect.mqtt.MqttSourceConnector",
        "tasks.max" : "1",
        "mqtt.server.uri" : "< Required Configuration >",
        "mqtt.topics" : "topic_2"
      }
    }
