> According to [Doris documentation|https://doris.apache.org/docs/sql-manual/sql-reference/Data-Definition-Statements/Alter/ALTER-TABLE-COLUMN/], altering column types dynamically is supported (via ALTER TABLE ... MODIFY COLUMN statement) when lossless conversion is available. However, now Doris pipeline connector has no support to AlterColumnTypeEvent, and raises RuntimeException all the time.
> It would be convenient for users if they can sync compatible type conversions, and could be easily implemented by extending Doris' SchemaChangeManager helper class.
