-------------------------------------
Assignee: Xiqian YU
> Doris pipeline sink does not support applying AlterColumnTypeEvent
> ------------------------------------------------------------------
>
> Key: FLINK-35072
> URL: https://issues.apache.org/jira/browse/FLINK-35072
> Project: Flink
> Issue Type: Improvement
> Components: Flink CDC
> Reporter: Xiqian YU
> Assignee: Xiqian YU
> Priority: Minor
> Labels: pull-request-available
>
> 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.
