HugeGraph Server consists of two layers of functionality: the graph engine layer, and the storage layer.
Graph Engine Layer:
REST Server: Provides a RESTful API for querying graph/schema information, supports the Gremlin and Cypher query languages, and offers APIs for service monitoring and operations.
Graph Engine: Supports both OLTP and OLAP graph computation types, with OLTP implementing the Apache TinkerPop3 framework.
Backend Interface: Implements the storage of graph data to the backend.
Storage Layer:
Storage Backend: Supports multiple built-in storage backends (RocksDB/Memory/HStore/HBase/...) and allows users to extend custom backends without modifying the existing source code.
