Worked on the kaltura/server repository to strengthen the update pipeline for batch operations involving dynamic attributes on kaltura_metadata. Focused on backend development using PHP, the work introduced robust error handling by implementing targeted try-catch blocks for PDOExceptions, specifically addressing unknown column errors. Enhanced logging was added to improve diagnosability of failures, while exception handling was refactored to generate granular, actionable messages for data inconsistencies. These improvements reduced ambiguous failures and increased maintainability, elevating data quality and operational resilience. The approach demonstrated a strong emphasis on database interaction and error handling, resulting in a more reliable and transparent update process.
