doris source is currently a one-time read, you can use the jdbc connector to achieve lookup join |

我试了一下，jdbc也是一次性读取的。难道是手动拼接sql的查询参数(where id=xxx)，每次都去查doris来实现join吗。。。 |

flinkCDC同步mysql到doris之后，想从doris里读取多张表到flink再进行join，弄成宽表重新插入doris。因为需要join的表在不同的数据库实例，flinkCDC只能同步一个数据库实例的多张表，所以不能在从mysql读取到flink时就进行join。目前尝试了从doris读取到flink是一次性的，有没有实时读取的功能呢。如果有其他方案也欢迎讨论。
