grapheekdb 0.0.1

GrapheekDB is a fast and lightweight Graph Database with various backends : Kyoto Cabinet/Local memory (more coming soon).

GrapheekDB is a fast and lightweight Graph Database with various KVS (Key/Value Store) backends :

• Local memory (default backend)

• Kyoto Cabinet : http://fallabs.com/kyotocabinet/

• Symas LMDB : http://symas.com/mdb/

Implementing a new backend for other KVS is quite easy : Local Memory backend is implemented in less that 50 lines of code.

Features :

• nodes (aka vertices) and edges creation and deletion

• nodes and edge lookup (using a django-like syntax)

• path traversal (using a gremlin-like syntax)

• basic nodes & edges indexing feature (works with one or many field)

• aggregation

• speed : path traversal often occurs at 1 million entities/second - thanks to the backends :)

• concurrency : with 1000 concurrent users and simple node creation/deletion, the server can handle 7000 requests/second - thanks to 0mq and gevent

• code base test coverage is currently : 100 %

Installation :

pip install grapheekdb
