## What it is
Apache HugeGraph is a fast, highly scalable graph database supporting tens of billions of vertices and edges with OLTP real-time queries via Gremlin, Cypher, and REST APIs. It forms a full-stack graph ecosystem including distributed OLAP graph computing (HugeGraph-Computer), GraphRAG/AI tooling (HugeGraph-AI), and a toolchain for loading, visualizing, and managing graph data.

## Use cases
- store and query billions of vertices and edges in real time
- run gremlin or cypher queries against a property graph
- build a knowledge graph for fraud detection or recommendations
- implement GraphRAG question answering over connected data
- run distributed graph algorithms like PageRank at scale
- import massive datasets into a graph database
- visualize and explore graph data in a web UI

## When to choose
- you need millisecond-level OLTP queries over very large graphs
- you want TinkerPop/Gremlin compatibility with pluggable backends
- you need both OLTP querying and OLAP graph computing in one ecosystem
- you are building GraphRAG or LLM-powered graph applications
- you need horizontal scaling from standalone to PB-level clusters

## When to avoid
- you need relational or document data models rather than property graphs
- you rely on MySQL, PostgreSQL, Cassandra, or ScyllaDB backends (removed in 1.7.0)
- your graph is small enough for simpler embedded options like SQLite-based stores
- you require full TinkerPop feature coverage such as threaded transactions
- you cannot run Java 11+ or operate JVM-based server infrastructure
