具有JSON模式的Kafka JDBC Sink连接器不起作用 [英] Kafka jdbc sink connector with json schema not working

问题描述

使用最新的kafka和融合的jdbc接收器连接器.发送一个非常简单的Json消息:

Using the latest kafka and confluent jdbc sink connectors. Sending a really simple Json message:

{
    "schema": {
        "type": "struct",
        "fields": [
            {
                "type": "int",
                "optional": false,
                "field": "id"
            },
            {
                "type": "string",
                "optional": true,
                "field": "msg"
            }
        ],
        "optional": false,
        "name": "msgschema"
    },
    "payload": {
        "id": 222,
        "msg": "hi"
    }
}

但是出现错误:

org.apache.kafka.connect.errors.DataException: JsonConverter with schemas.enable requires "schema" and "payload" fields and may not contain additional fields. If you are trying to deserialize plain JSON data, set schemas.enable=false in your converter configuration.

Jsonlint说Json有效.我将json schemas.enable=true保留在kafka配置中.有指针吗?

Jsonlint says the Json is valid. I have kept json schemas.enable=true in kafka configuration. Any pointers?

推荐答案

您需要告诉Connect您的架构已嵌入在您使用的JSON中.

You need to tell Connect that your schema is embedded in the JSON you're using.

您有:

value.converter=org.apache.kafka.connect.json.JsonConverter 

但还需要:

value.converter.schemas.enable=true
