In modern data architectures, keeping analytical stores like Apache Doris in sync with operational databases is a common challenge. This post explores a robust pattern using two Apache projects: SeaTunnel for data movement and DolphinScheduler for orchestration. The key innovation is using DolphinScheduler to capture the last sync checkpoint and pass it as a parameter to SeaTunnel, enabling reliable incremental loads without custom scripting. This approach reduces operational complexity and ensures data consistency. For teams already using Doris for real-time analytics, this pattern offers a production-ready solution for batch incremental updates. The integration leverages each tool's strengths: DolphinScheduler's workflow management and SeaTunnel's connector ecosystem. While the original post provides a step-by-step tutorial, the architectural pattern itself is broadly applicable to any MySQL-to-Doris pipeline requiring scheduled incremental syncs.
A practical guide to integrating Apache SeaTunnel and Apache DolphinScheduler for offline incremental sync from MySQL to Doris, using checkpoint-based parameter passing.
