Enriching the messages

Comment

Read the individual events from a Kafka topic called input-messages

Validate the message, sending any defective event to a dedicated Kafka topic called invalid-messages

Enrich the message with the geographic location data

Write the enriched messages in a Kafka topic called valid-messages

package monedero;

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import com.maxmind.geoip.Location;
import monedero.extractors.GeoIPService;
import org.apache.kafka.clients.producer.KafkaProducer;
import java.io.IOException;

public final class Enricher implements Producer {
  private final KafkaProducer<String, String> producer;
  private final String validMessages;
  private final String invalidMessages;
  private static final ObjectMapper MAPPER = new ObjectMapper();
  public Enricher(String servers, String validMessages, String 
    invalidMessages) {
    this.producer = new KafkaProducer<> 
    (Producer.createConfig(servers));
    this.validMessages = validMessages;
    this.invalidMessages = invalidMessages;
  }
  @Override
  public void process(String message) {
    try {
      // this method below is filled below  
    } catch (IOException e) {
      Producer.write(this.producer, this.invalidMessages, "{\"error\": \""
          + e.getClass().getSimpleName() + ": " + e.getMessage() + "\"}");
    }
  }
}
