- Fixes a bug in SchemaUtils.applyAddColumnEvent where AddColumnEvent column positioning fails if the referenced existing column name differs only by case.
- Implementation:
-
- SchemaUtils.applyAddColumnEvent now finds the referenced column by:
-
-
- exact name match
-
-
-
- fallback to case-insensitive match
-
- Added regression coverage in SchemaUtilsTest
- No other behavior changes for exact matching
- Testing
-
- mvn -pl flink-cdc-common -Dtest=SchemaUtilsTest test
…ed existing column name differs only by case
