#graphframes
This is a prototype package for DataFrame-based graphs on top of Apache Spark. Users can write highly expressive queries by leveraging the DataFrame API, combined with a new API for motif finding. The user also benefits from DataFrame performance optimizations within the Spark SQL engine.
Merging with Spark: The ultimate goal is to provide DataFrame-based graphs in Spark itself. This package will provide a public API for this work, until the time when this work can be merged into Spark itself.
To compile this project, run build/sbt assembly from the project home directory.
This will also run the Scala unit tests.
To run the Python unit tests, run the run-tests.sh script from the python/ directory.
You will need to set SPARK_HOME to your local Spark installation directory.
This project is compatible with Spark 1.4+. However, significant speed improvements have been made to DataFrames in more recent versions of Spark, so you may see speedups from using the latest Spark version.
GraphFrames is collaborative effort among UC Berkeley, MIT, and Databricks. We welcome open source contributions as well!
