汇合s3汇在哪里放钥匙？

Question

我设置了一个汇合的s3 sink connect，它在.s3中存储了.avro文件。 我转储这些文件，并发现它们只是消息本身，我不知道在哪里可以找到消息密钥，任何想法？

配置如下：

{
    "name": "s3-sink-test",
    "config": {
        "connector.class": "io.confluent.connect.s3.S3SinkConnector",
        "tasks.max": "1",
        "topics": "book",
        "s3.region": "eu-central-1",
        "s3.bucket.name": "kafka",
        "s3.part.size": "5242880",
        "storage.class": "io.confluent.connect.s3.storage.S3Storage",
        "format.class": "io.confluent.connect.s3.format.avro.AvroFormat",
        "schema.generator.class": "io.confluent.connect.storage.hive.schema.DefaultSchemaGenerator",
        "partitioner.class": "io.confluent.connect.storage.partitioner.TimeBasedPartitioner",
        "path.format": "'year'=YYYY/'month'=MM/'day'=dd/'hour'=HH",
        "locale": "US",
        "timezone": "UTC",
        "partition.duration.ms": "3600000",
        "timestamp.extractor": "RecordField",
        "timestamp.field": "local_timestamp",
        "flush.size": "2",
        "schema.compatibility": "NONE"
    }
}

Kafka消息密钥不会被Confluent的任何存储Kafka连接器保持开箱即用

尝试编译和设置Archive Transform，可以使用Connect Configuration中的这些属性进行设置

"transforms" : "tran",
"transforms.tran.type" : "com.github.jcustenborder.kafka.connect.archive.Archive"
