# Proposed changes Issue Number: close #xxx ## Problem Summary: The original `JsonDebeziumSchemaSerializer` contains two serialization logics: record and schema change, which makes the entire `JsonDebeziumSchemaSerializer` code logic particularly confusing and complex, and the maintenance cost is high. Now record and schema change are separated into `JsonDebeziumRecord` and `JsonDebeziumSchemaChange`. There are two versions of schema implementation in `JsonDebeziumSchemaChange`. One is the old version(`JsonDebeziumSchemaChangeImpl`), which has limited support for schema change in actual business; the other is a new version(`JsonDebeziumSchemaChangeImplV2`), which supports newer versions and can support multi-column changes and field renaming. ## Checklist(Required) 1. Does it affect the original behavior: (Yes/No/I Don't know) 2. Has unit tests been added: (Yes/No/No Need) 3. Has document been added or modified: (Yes/No/No Need) 4. Does it need to update dependencies: (Yes/No) 5. Are there any changes that cannot be rolled back: (Yes/No) ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
