RedisGraph vs Titan: What are the differences?

Developers describe RedisGraph as "A High Performance In-Memory Graph Database as a Redis Module". RedisGraph is a graph database developed from scratch on top of Redis, using the new Redis Modules API to extend Redis with new commands and capabilities. Its main features include: - Simple, fast indexing and querying - Data stored in RAM, using memory-efficient custom data structures - On disk persistence - Tabular result sets - Simple and popular graph query language (Cypher) - Data Filtering, Aggregation and ordering. On the other hand, Titan is detailed as "Distributed Graph Database". Titan is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster. Titan is a transactional database that can support thousands of concurrent users executing complex graph traversals in real time.

RedisGraph and Titan belong to "Graph Databases" category of the tech stack.
