如何配置kafka connect使用Avro Schema？

Question

我已經開始學習 Avro。 我想在kafka connect中實現它。 我使用如下配置。 這是正確的配置嗎？

{
    "name": "surveyWawancara-connector",
    "config": {
        "connector.class": "io.debezium.connector.sqlserver.SqlServerConnector",
        "key.deserializer": "org.apache.kafka.connect.json.JsonDeserializer",
        "database.user": "Acquisition.ro",
        "database.dbname": "acquisition",
        "value.deserializer": "org.apache.kafka.connect.json.JsonDeserializer",
        "tasks.max": "1",
        "key.converter": "io.confluent.connect.avro.AvroConverter",
        "key.converter.schema.registry.url": "http://localhost:8081",
        "value.converter": "io.confluent.connect.avro.AvroConverter",
        "value.converter.schema.registry.url": "http://localhost:8081",
        "database.history.kafka.bootstrap.servers": "beta-kafka-brokers.amq-streams-beta.svc:9092",
        "database.history.kafka.topic": "schema-changes.sl.surveyWawancara",
        "time.precision.mode": "connect",
        "database.server.name": "beta-sl-bn",
        "database.port": "1433",
        "table.whitelist": "dbo.SurveyWawancara",
        "key.converter.schemas.enable": "true",
        "database.hostname": "10.7.76.62",
        "database.password": "Acquisition_ro231!",
        "value.converter.schemas.enable": "true",
        "name": "surveyWawancara-connector",
        "value.converter": "org.apache.kafka.connect.json.JsonConverter",
        "key.converter": "org.apache.kafka.connect.json.JsonConverter"
    }
}

您已經復制了轉換器字段，但這些屬性是正確的，是的

"key.converter": "io.confluent.connect.avro.AvroConverter",
"key.converter.schema.registry.url": "http://localhost:8081",
"value.converter": "io.confluent.connect.avro.AvroConverter",
"value.converter.schema.registry.url": "http://localhost:8081", 

Avro 總是有一個模式，所以這些都不做*.schemas.enable並且可以被刪除。 同樣，解串器 class 配置不適用於 Connect，並且包含在轉換器配置中，因此也應刪除

值得一提的是，密鑰格式不必（而且通常不會）與值的匹配
