我们可以使用该连接器来将Apache Kafka中的数据写入Google Cloud Storage中,同时将数据转换为Avro格式。下面是使用Java编写的示例代码:
首先,我们需要添加以下Maven依赖项:
org.apache.camel
camel-avro
x.x.x
org.apache.camel
camel-google-storage
x.x.x
org.apache.camel
camel-kafka
x.x.x
然后,我们可以使用以下代码来编写路由:
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.google.storage.GoogleCloudStorageConstants;
import org.apache.camel.model.dataformat.AvroDataFormat;
public class MyRouteBuilder extends RouteBuilder {
@Override
public void configure() throws Exception {
// Configure the Avro data format
AvroDataFormat avroDataFormat = new AvroDataFormat(MyRecord.class);
// Configure the Google Cloud Storage component
String bucketName = "my-bucket";
String storageEndpoint = "https://storage.googleapis.com";
String credentialsFile = "/path/to/credentials.json";
getContext().getComponent("google-storage", GoogleCloudStorageComponent.class)
.setCamelContext(getContext())
.setBucketName(bucketName)
.setEndpoint(storageEndpoint)
.setCredentialsFile(credentialsFile);
// Configure the Kafka component
String brokers = "localhost:9092";
String topic = "my-topic";
getContext().getComponent("kafka", KafkaComponent.class)
.setBrokers(brokers);
// Create the route
from("kafka:" + topic)
.unmarshal(avroDataFormat)
.setHeader(GoogleCloudStorageConstants.KEY, constant("file.avro"))
.to("google-storage://insert?autoCreateBucket=true");
}
}
在此示例中
