I'm sorry for the schema change https://github.com/apache/doris-kafka-connector/pull/14 implemented before. The previous PR implementation method, due to the need to read the topic of a specific `schema.topic`, this implementation method may cause kafka-connect to read the data topic first instead of the `schema.topic` when starting up. In this case, under certain circumstances Will cause data in the imported change column to be missing. The current schema change is to parse the data column and compare it with the schema read from doris to determine whether it is missing to determine whether the column needs to be added. So we also exclude the `schema.topic` parameter, if you want to use the schema change function, you need to set `schema.evolution` to `BASIC`. This parameter defaults to `NONE` and schema change is not supported. -- This is an automated message from the Apache Git Service.
