GraphStore
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
