Marius Eriksen: Distributed, Incremental Dataflow Processing in the Cloud with Reflow

Marius Eriksen

The Braille bioinformatics team has developed Reflow, an open-source workflow engine designed to treat biological data pipelines as functional programs rather than static dependency graphs. By enforcing a strict data model and dynamic cloud resource provisioning, the system automatically parallelizes tasks, caches results through referential transparency, and ensures reproducible computations via versioned "data spaces." Currently adopted by Grail, the Chan Zuckerberg Institute, and several biotech startups, Reflow reduces infrastructure complexity while enabling efficient incremental updates to massive genomic and machine learning pipelines.
