What is Apache HugeGraph?

HugeGraph is a fast and highly-scalable graph database. Billions of vertices and edges can be easily stored into and queried from HugeGraph due to its excellent OLTP capabilities. HugeGraph is compliant with the Apache TinkerPop 3 framework allowing complicated graph queries to be achieved through the powerful Gremlin graph traversal language.

Features

• Compliant to Apache TinkerPop 3, supports Gremlin & Cypher language
• Schema Metadata Management, including VertexLabel, EdgeLabel, PropertyKey and IndexLabel
• Multi-type Indexes, supporting exact query, range query and complex conditions combination query
• Plug-in Backend Store Framework, mainly support RocksDB/HStore + HBase for now and you could choose other backends in the legacy version ≤ 1.5.0 (like MySQL/PG/Cassandra ...)
• Integration with Flink/Spark/HDFS, and friendly to connect other big data platforms
• Complete graph ecosystem (including both in/out-memory Graph Computing + Graph Visualization & Tools + Graph Learning & AI, see here)

Quick Start

1. Docker (For Test)

Use Docker to quickly start a HugeGraph server with RocksDB (in the background) for testing or development:

# (Optional) 
# 1. add "-e PASSWORD=xxx" to enable the auth system
# 2. add "-e PRELOAD="true" to auto-load a sample graph
docker run -itd --name=graph -p 8080:8080 hugegraph/hugegraph:1.5.0

Please visit doc page or the README for more details. (Docker Compose)

Note:

1. The Docker image of HugeGraph is a convenience release, but not official distribution artifacts. You can find more details from ASF Release Distribution Policy.
2. Recommend to use release tag (like 1.5.0/1.x.0) for the stable version. Use latest tag to experience the newest functions in development.

2. Download

Visit Download Page and refer the doc to download the latest release package and start the server.

Note: if you want to use it in the production environment or expose it to the public network, must enable the AuthSystem to ensure safe.

3. Build From Source

Visit Build From Source Page and follow the steps to build the source code and start the server.

The project doc page contains more information on HugeGraph and provides detailed documentation for users. (Structure / Usage / API / Configs...)
