smt不使用以下配置，任何想法
"transforms": "createKey",
"transforms.createKey.type":"org.apache.kafka.connect.transforms.ValueToKey",
"transforms.createKey.fields":"column_id",
getting below exception

在kafka-connect中还添加了配置： key.converter.schemas.enable=true value.converter.schemas.enable=true，以启用类ValueTokey所需的模式
这可能迟到了，但对我来说，问题很敏感。我的列名是ID，在配置中是ID。因此，下面是对我有用的配置
transforms=createKey
transforms.createKey.fields=ID
transforms.createKey.type=org.apache.kafka.connect.transforms.ValueToKey
