MySQL CDC to BigQuery: what periodic syncs miss, and how binlog avoids it

MySQL's periodic batch syncs miss deleted rows, intermediate updates, and waste production database resources, while Change Data Capture (CDC) using MySQL's binary log captures every INSERT, UPDATE, and DELETE in order with complete row state. CDC requires specific MySQL configurations including binary logging in ROW format with FULL row images, proper replication privileges, unique server IDs, and sufficient binlog retention to ensure reliable data syncing to BigQuery without data loss.
