JNSimba opened a new pull request, #64: URL: https://github.com/apache/doris-flink-connector/pull/64
## Problem Summary: Support Light Schema Change, such as FlinkCDC scenarios. **Main process** 1. Customize JsonDebeziumSchemaSerializer to get records passed by CDC (JsonDebeziumDeserializationSchema format) 2. Parse the database name, table name, and DDL statement in the record (only support add/drop column) 3. Call `/api/enable_light_schema_change/db/table` to check whether the table can do light schema change 4. If the 3 verification is successful, call `/api/query/default_cluster/db` to perform the schema change operation 5. If 2, 3, and 4 fail, it will not affect the main process of Flink processing data, and only output the error log. ## 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.
