Tributary is a library for constructing dataflow graphs in Python. Unlike many other DAG libraries in Python (airflow, luigi, prefect, dagster, dask, kedro, etc), tributary is not designed with data/etl pipelines or scheduling in mind. Instead, tributary is more similar to libraries like mdf, loman, pyungo, streamz, or pyfunctional, in that it is designed to be used as the implementation for a data model. One such example is the greeks library, which leverages tributary to build data models for options pricing.

Features

  • Tributary offers several kinds of streams
  • Functional streams, built by currying python functions (callbacks)
  • These are lazily-evaluated python streams
  • Graph Visualization
  • You can visualize the graph with Graphviz
  • All streaming and lazy nodes support a graphviz method
