Welcome to Fallen-8.

Fallen-8 is an in-memory graph database implemented in C#. Its focus is to provide raw speed for heavy graph algorithms.

Key featues

  • Properties on vertices and edges
  • Indexes on vertices and edges
  • Plugins for indexes, algorithms and services
  • Checkpoint persistency

Sweet spots

  • Enterprise Search (Semantic adhoc queries on multi-dimensional graphs)
  • Lawful Interception (Mass analysis)
  • E-Commerce (Bid- and portfolio-management)

HowTo Clone

Fallen-8 makes use of git submodules, that's why they have to be cloned too.

$ git clone --recursive git@github.com:cosh/fallen-8.git

HowTo Use

var fallen8 = new Fallen8();

//start the built-in services
fallen8.ServiceFactory.StartGraphService();
fallen8.ServiceFactory.StartAdminService();
