Meta's migration of its petabyte-scale MySQL ingestion platform demonstrates that zero-downtime transitions at massive scale are achievable through rigorous techniques like reverse shadowing and continuous checksum monitoring. By replacing fragmented customer-owned pipelines with a centralized, self-managed warehouse service, the company successfully consolidated thousands of ingestion jobs while maintaining compatibility for downstream analytics and machine learning workloads. This case study highlights the operational value of staged migrations and automated validation controls for managing complex distributed data systems.
