GraphStore is an in-memory graph structure implementation written in Java. It's designed to be powerful, efficient and robust. It's powering the Gephi software and supports large graphs in intensive applications.

## Features Highlight

* Blazing fast graph data structure optimized for reading and writing

* Comprehensive APIs to read and modify the graph structure

* Low memory footprint - reduced usage of Java objects and collections optimized for caching

* Supports directed, undirected and mixed graphs

* Supports parallel edges (i.e. edges can have a label)

* Any number of attributes can be associated with nodes or edges

* Thread-safe - Implements read-write locking mechanism to allow multiple reading threads

* Supports dynamic graphs (graphs over time)

* Built-in index on attribute values

* Fast and compact binary serialization

* Spatial indexing based on a quadtree
