如何连接 Apache Kafka 和 Amazon S3？

Question

我想使用 Kafka Connect 将来自 Kafka 的数据存储到存储桶 s3 中。我已经有一个 Kafka 的主题运行并且我创建了一个 bucket s3。我的主题有关于 Protobuffer 的数据，我尝试使用 https://github.com/qubole/streamx 并得到下一个错误：

我做了接下来的步骤：

我克隆了存储库。
mvn DskipTests package

nano config/connect-standalone.properties

bootstrap.servers=ip-myip.ec2.internal:9092
key.converter=com.qubole.streamx.ByteArrayConverter
value.converter=com.qubole.streamx.ByteArrayConverter

nano config/quickstart-s3.properties

name=s3-sink 
connector.class=com.qubole.streamx.s3.S3SinkConnector
format.class=com.qubole.streamx.SourceFormat tasks.max=1
topics=ssp.impressions
flush.size=3
s3.url=s3://myaccess_key:mysecret_key@mybucket/demo

connect-standalone /etc/kafka/connect-standalone.properties quickstart-s3.properties

我想知道我这样做是否可行，或者是否可以通过其他方式将数据从 Kafka 保存到 S3。

Answer 1

您可以使用 Kafka Connect 通过 Kafka Connect S3 连接器进行此集成。

Kafka Connect is part of Apache Kafka, and the S3 connector is an open-source connector available either standalone or as part of Confluent Platform.

免责声明：我在 Confluent 工作，并撰写了上述博客文章。

2020 年 4 月：我录制了一段视频，展示了如何使用 S3 接收器：https://rmoff.dev/kafka-s3-video

Answer 2

另一种方法是编写一个具有日志轮换功能的消费者，然后将玉米文件写入 S3。
