A production-grade integration layer for distributed data systems, with fault tolerance, schema evolution, and multi-engine execution across batch, streaming, CDC, multimodal, and AI workloads.
Architecture Pattern
SeaTunnel handles extract, lightweight transform, and load. Your warehouse or lakehouse can keep the heavy downstream transformation while SeaTunnel moves reliable, structured data between systems.
Why SeaTunnel
Real fault tolerance, schema evolution, and multi-engine scale for production pipelines.
SeaTunnel detects upstream schema changes and propagates them downstream in real time, so teams do not need to pause the pipeline for every column change.
# Before -> After (detected automatically) -- v1 schema ------------------------- id BIGINT name VARCHAR(255) -- v2 schema (auto-propagated) ------ id BIGINT name VARCHAR(255) email VARCHAR(512) NEW phone VARCHAR(32) ADDED
Low-latency change capture across major databases, with seamless batch-to-stream handoff and no lock-based cutover.
Checkpoint-backed fault tolerance keeps records consistent across failures, retries, and restarts.
Use the same pipeline definition on Zeta, Flink, or Spark without rewriting connector logic or delivery paths.
~200 Native Connectors
Native connectors across databases, streams, lakehouses, search systems, and object stores.
Simple by design
Declare your source, transform, and sink in plain config, then deploy on any supported engine without rewriting the pipeline.
