:clipboard: Description

Memgraph is a high-performance, in-memory graph database that powers real-time AI context and graph analytics. Built in C/C++, it serves as the graph engine for GraphRAG pipelines, AI memory systems, and agentic workflows — delivering sub-millisecond multi-hop traversals for any system that needs structured, connected context alongside semantic vector or text search.

Memgraph provides both in a single query layer: built-in text and vector indexes for similarity search combined with full graph traversal, so retrieval pipelines can run as a single atomic database operation instead of being scattered across multiple systems.

The same architecture drives real-time graph analytics for fraud detection, network analysis, infrastructure monitoring, and other operational workloads where performance matters. Memgraph is fully compatible with Neo4j’s Cypher query language, ACID-compliant, and highly available.

:zap: Features

AI & Graph Intelligence

• Indexes - Built-in vector indexes power hybrid graph retrieval with similarity search in a single query, alongside text and geospatial indexes for keyword and location-aware queries.
• MAGE algorithm library - 40+ graph algorithms in C++, Python, and CUDA including PageRank, community detection, GNN-based link prediction, temporal graph networks, embeddings, and native ML.
• Atomic GraphRAG - Pivot search, graph expansion, ranking, and prompt assembly expressed as a single Cypher query.
• LLM utility module - Graph-aware context formatting for large language models.
• AI Toolkit - Integrations with popular agentic frameworks, MCP server, and ready-made components for building GraphRAG, AI memory, and agent workflows on top of Memgraph.
• Real-time schema introspection - SHOW SCHEMA INFO returns the full graph ontology for Text2Cypher and AI agent integration.

Performance & Query Power

• In-memory C/C++ engine - Sub-millisecond traversals with benchmarked performance.
• Deep-path traversals - Accumulators and path filtering without additional application logic.
• Custom query modules - Extend with Python, Rust, and C/C++ code natively.
• Parallel query execution - Concurrent query processing for high-throughput workloads.
• Native Parquet & JSONL loading - Load data directly from Parquet and JSONL files on local disk, S3, or HTTP endpoints.
• Streaming support - Ingest from Kafka, Pulsar, and RedPanda with dynamic graph algorithms that react to changes in real time.

Enterprise

• High availability - Raft-based coordination with automatic failover.
• Multi-tenancy - Isolated databases with per-tenant role assignments.
• Fine-grained access control - Role-based and label-based permissions at the node and edge level.
• Authentication & authorization - SSO integration, user impersonation, and 30+ granular permissions.
• Encryption in transit, monitoring, backup & restore.
