以下是使用 flink-s3-fs-hadoop 插件将 Flink 流式数据写入 MinIO 存储桶的示例代码:
```java
import org.apache.flink.streaming.api.datastream.DataStream;
import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;
import org.apache.flink.streaming.connectors.fs.bucketing.BucketingSink;
import org.apache.flink.streaming.connectors.fs.bucketing.DateTimeBucketer;
import org.apache.flink.streaming.connectors.fs.StringWriter;
import org.apache.flink.streaming.connectors.fs.SequenceFileWriter;
import org.apache.flink.streaming.connectors.fs.bucketing.BucketingSink;
import org.apache.flink.streaming.connectors.fs.bucketing.DateTimeBucketer;
public class WriteToMinIO {
public static void main(String[] args) throws Exception {
final StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
// 创建一个DataStream,假设它包含字符串
DataStream<String> stream = env.fromElements("Hello", "World", "Flink");
// 创建一个BucketingSink,将流式数据写入MinIO存储桶中
BucketingSink<String> sink = new BucketingSink<>("s3a://my-bucket-name/path/to/files");
sink.setBucketer(new DateTimeBucketer<>("yyyy-MM-dd--HHmm"));
sink.setWriter(new StringWriter<>());
// 将DataStream写入BucketingSink
stream.addSink(sink);
// 执行Flink作业
env.execute("WriteToMinIO");
}
}
```
在上面的示例中,我们使用 `BucketingSink` 将 Flink 流式数据写入 MinIO 存储桶。我们设置了 `DateTimeBucketer` 作为文件桶,并使用 `StringWriter` 将数据写入文本文件。最后,我们将 `DataStream` 写入 `BucketingSink` 并执行 Flink 作业。请注意,我们在 s3a URL 中指定了 MinIO 存储桶的名称和路径。
