GoKawiilCDC via MySQL binlog closes gaps left by scheduled BigQuery syncs
A technical breakdown explains why standard periodic MySQL-to-warehouse syncs, which query and diff table snapshots on a schedule, can silently miss deleted rows and intermediate row states between runs while also straining production databases. It contrasts this with Change Data Capture, which reads MySQL's binary log directly to capture every insert, update, and delete in order with complete row data, rather than inferring changes from comparisons.
