About

Vertex is a high performance graph database that supports automatic garbage collection, built on libevent and tokyocabinet. It uses HTTP as it's communication protocol and JSON as it's response data format. It's BSD licensed and was written by Steve Dekorte and Rich Collins. See docs/manual.html for API and more details.

Status

Currently in production use and working well so far. The API is still not set in stone though.

Usage

Compiling on Mac OS X

sudo port install yajl tokyocabinet libevent libzip
# or if you are using homebrew
brew install yajl tokyo-cabinet libevent
cmake .
make
sudo make install

If all was fine, in build/vertexdb will be bin file

Running

vertexdb -db blog1.db

or as daemon

sudo vertexdb -db /opt/database -d --pid /var/run/vertex.pid
