Questions About Hiring a Senior Zero-Downtime Database Migration Specialist
How do you guarantee zero data loss during cutover?
We run real-time CDC replication until replication lag is zero, pause write traffic for under 30 seconds, synchronize serial sequences, and switch DNS.
Does CDC replication slow down the active production database?
No, because CDC reads transaction logs directly from disk (WAL/binlog) rather than running SQL queries, CPU overhead is typically under 2%.
