Introduction

Rucio is a CERN software system for storing file metadata and organizing the delivery of that data to users. Its primary features are scalability, flexibility, adaptive file replication, and built-in monitoring. It can use various backends for databases, various platforms for its servers and daemons, various transfer and storage method plug-ins, and a command line and python interface for users.

The new system would consist of these parts

  • Metacat - a database of file metadata (docs)
  • Rucio - a database of file locations, and servers which can move and track data, responding to user rules (docs)
  • Data Dispatcher - a modern replacement for SAM project file delivery ()
  • mdh - Mu2e data-handling commands added to supplement the above systems (see mdh -h)
