Overview
NebulaGraph
NebulaGraph is a distributed, open-source graph database built to handle super-large datasets with hundreds of billions of nodes and trillions of edges. You can store and query complex relationships at scale while maintaining millisecond-level latency, making it ideal for real-time applications. The architecture separates computing from storage, which allows you to scale your resources independently based on your specific workload requirements.
You can use NebulaGraph to power recommendation engines, detect fraud in real-time, or map out intricate social networks. It supports a SQL-like query language called nGQL, so your team can transition quickly without learning entirely new syntax. Whether you are managing identity graphs or performing deep-link analysis, this platform provides the high availability and fault tolerance needed for mission-critical enterprise environments.
PostgreSQL
PostgreSQL gives you a powerful, open-source object-relational database system with over 35 years of active development. You can manage massive volumes of data while ensuring high levels of resilience and integrity. It supports both SQL for relational queries and JSON for non-relational data, giving you the flexibility to build diverse applications without switching platforms.
You can extend the database with your own data types, custom functions, and code from different programming languages. Whether you are building a simple web app or a complex enterprise system, it provides the tools to maintain data consistency and performance. Because it is open-source, you get a feature-rich environment without licensing fees, supported by a global community of developers.
