Worked on enhancing the reliability of the OceanBase-backed data pipeline in the infiniflow/ragflow repository by addressing schema migration issues. Focused on backend development and database management, the work involved using Python and SQLAlchemy to ensure that the chunk_data column was properly included during schema alterations. This fix prevented data insertion errors related to unconsumed column names and aligned the migration process with the updated table structure. By updating the schema initialization logic, the changes reduced operational risk and improved data integrity, prioritizing technical debt reduction and system stability over new feature development during the reported period.
