FlinkKafkaConsumer API 维表关联

各位好：

请教一下，用FlinkKafkaConsumer API的话，如何支持SQL的方式，和维表关联。（之前用Kafka API&StreamTableDescriptor API是可以的）
 "select  a.id,b.name from kafka_table a "
        + "join dim_table FOR SYSTEM_TIME AS OF a.proctime as b on a.id = b.user_id";

thanks & Regards

你需要用 DDL 去声明这张 kafka 表[1], 目前不建议使用 `Kafka` 和 `StreamTableDescriptor` API。

Best,
