Doris connector ignores all default value fields for now. Will add test cases after apache/doris-flink-connector#490 got merged. |

Doris sink connector requires specifying default value expression explicitly when altering column types. However, default value fields are not present in
AlterColumnTypeEventfor now. This could be resolved by backfilling pre-schema info withPreSchemainterface.
