discoproject/disco

Disco is a distributed computing framework that manages cluster operations, job scheduling, and data processing. It provides a Python-based CLI and web interface for controlling the master and nodes, while supporting MapReduce and pipeline-based job execution across various storage backends like HDFS, S3, and Redis. The system includes a distributed filesystem (DDFS) for data management and offers deployment automation for cloud environments.

How it got here

2008 · Initial project structure and tooling

This period established the foundational architecture of the Disco project, replacing legacy Python and shell-based build systems with a standardized Erlang/Rebar build process and C bindings. The team implemented core utility modules, configuration constants, and a new Sphinx-based documentation structure to support the framework's development.

2009–2010 · Distributed storage and CLI tooling

This period focused on introducing the DDFS distributed file system and a comprehensive set of command-line interfaces for cluster and data management. The team also reorganized the Python library structure to support multiple input schemes and improved Python 3 compatibility across the codebase.

15 changes

2011–2014 · Packaging, testing, and deployment infrastructure

This period focused on stabilizing the codebase through comprehensive test coverage and introducing robust packaging for Debian and RPM distributions. It also expanded deployment options with Docker, systemd, and cloud automation scripts, while providing practical examples for complex workflows like job chaining and MapReduce algorithms.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 29 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit be65272d3e — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
