Kafka JDBC Sink连接器-Oracle

Question

I am creating jdbc sink connector(confluent) to oracle, first time. Below is the connector config. It is not creating and loading the table, but offset is being increased as per log and no error thrown in the log. Please suggest what could be the issue.

Producing through java, 5 sample records. I have tried curl to check the status, it is running.

{
    "name": "ora_sink_task",
    "config": {
            "connector.class": "io.confluent.connect.jdbc.JdbcSinkConnector",
            "connection.url": "jdbc:oracle:thin:@host:port/servicename",
            "connection.user": "user",
            "connection.password": "password",
            "topics": "connecttest",
            "tasks.max": "1",
            "table.name.format": "member_cbdt_sink1",
            "value.converter":"io.confluent.connect.avro.AvroConverter",
            "value.converter.schema.registry.url":"http://localhost:8081",
            "auto.create": "true"
            }
}

Connector log:

当Oracle查找大写字母时，它通过将table.name.format的值从小写更改为大写来工作。
