This page tracks external software projects that supplement Apache Spark and add to its ecosystem.

To add a project, open a pull request against the spark-website repository. Add an entry to this markdown file, then run jekyll build to generate the HTML too. Include both in your pull request. See the README in this repo for more information.

Note that all project and product names should follow trademark guidelines. is an external, community-managed list of third-party libraries, add-ons, and applications that work with Apache Spark. You can add a package as long as you have a GitHub repository.

Infrastructure projects

Applications using Spark

  • Apache Mahout - Previously on Hadoop MapReduce, Mahout has switched to using Spark as the backend
  • Apache MRQL - A query processing and optimization system for large-scale, distributed data analysis, built on top of Apache Hadoop, Hama, and Spark
  • BlinkDB - a massively parallel, approximate query engine built on top of Shark and Spark
  • Spindle - Spark/Parquet-based web analytics query engine
  • Thunderain - a framework for combining stream processing with historical data, think Lambda architecture
  • Oryx - Lambda architecture on Apache Spark, Apache Kafka for real-time large scale machine learning
  • ADAM - A framework and CLI for loading, transforming, and analyzing genomic data using Apache Spark
  • TransmogrifAI - AutoML library for building modular, reusable, strongly typed machine learning workflows on Spark with minimal hand tuning
  • Natural Language Processing for Apache Spark - A library to provide simple, performant, and accurate NLP annotations for machine learning pipelines
  • Rumble for Apache Spark - A JSONiq engine to query, with a functional language, large, nested, and heterogeneous JSON datasets that do not fit in dataframes.

Performance, monitoring, and debugging tools for Spark

  • Performance and debugging library - A library to analyze Spark and PySpark applications for improving performance and finding the cause of failures
  • Data Mechanics Delight - Delight is a free, hosted, cross-platform Spark UI alternative backed by an open-source Spark agent. It features new metrics and visualizations to simplify Spark monitoring and performance tuning.

Additional language bindings
