Tongcheng Travel, a major Chinese online travel agency, faced a common data infrastructure challenge: four separate data channel systems (data transfer, data integration, Sqoop, and SeaTunnel) running in parallel, leading to functional overlap, engine fragmentation, and high operational costs. They consolidated all data channels into a single unified pipeline built on Apache SeaTunnel. This case study details the migration strategy, technical decisions, and operational outcomes. Key benefits included reduced maintenance overhead, simplified data governance, and improved developer productivity. For engineering leaders dealing with similar data infrastructure sprawl, this provides a practical blueprint for consolidation using an open-source framework.
Tongcheng Travel replaced four separate data channel systems with a single Apache SeaTunnel-based unified pipeline, reducing costs and eliminating engine fragmentation.
