---------------------------------
Summary: 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
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.
