(Data Definition Language, like ALTER TABLE) while the CDC capture job is still actively processing changes from other tables. Recommended Solution

If you are seeing this identifier in your SSIS logs (such as the BufferSizeTuning event), it may be part of a GUID (e.g., {...-E180FA5DB913} ) used to identify a specific Data Flow Task

occurs when the CDC capture job fails while processing changes for a table that utilizes system CLR data types hierarchyid Technical Cause

: In some cases, switching from an ADO.NET data source to an ODBC source can significantly improve throughput. Buffer Tuning : Adjusting the DefaultBufferMaxRows DefaultBufferSize

: Manually trigger the CDC capture job to ensure all pending DML changes are fully processed. Execute DDL : Apply your schema changes (DDL). Final Capture : Run the capture job again to process the DDL changes. Resume DML : Re-enable standard data processing for the table. Monitoring and Debugging

This specific failure is triggered by a sequence of operations on the same table: Enabling CDC on a table with CLR data types. DML changes (Data Manipulation Language, like INSERT or UPDATE). DDL changes

properties to handle larger batches of rows, though SSIS may still limit these if the rows are too wide. or specific performance tuning for large SSIS packages?

within your package. If performance is the primary "hot" issue, consider: Provider Optimization
