Effective DDL Strategy in CDC

Having a strategic approach to managing DDLs is crucial in Change Data Capture (CDC) processes. It is important to balance keeping pipelines online with preventing the accumulation of transactions that could disrupt target systems and reports. Backfilling events and queuing them up before applying DDLs ensures minimal data loss and easy restart. Time is critical in CDC to prevent the loss of open transactions due to pipeline downtime. Resync in CDC involves retrieving and batch-loading transactions from the time of pipeline downtime before restarting the process from the last recorded event, which is labor-intensive and complex.
