Azure Cosmos DB
Fully managed, globally distributed NoSQL database service offering multi-model support with low-latency access worldwide
OrientDB
Versatile multi-model NoSQL DBMS with native graph, document, and full-text support
OrientDB combines graph, document, key‑value, full‑text, and geospatial models in a single engine, offering ACID transactions, SQL queries, and runnable on any platform via Java.
Overview
Overview
OrientDB is a Java‑based multi‑model database that unifies graph, document, key‑value, full‑text, and geospatial data structures. It targets developers, data engineers, and architects who need flexible data modeling without managing multiple specialized systems.
Core Capabilities
The engine offers ACID‑compliant transactions and a full SQL layer, allowing teams familiar with relational queries to interact with NoSQL data. Persistent pointers replace costly runtime joins, delivering rapid traversals across millions of records. Built‑in full‑text indexing, geospatial queries, and reactive APIs enable advanced search and real‑time analytics.
Deployment & Operations
Running on any platform with a Java runtime, OrientDB requires no complex installation. Its multi‑master architecture provides high availability and horizontal scalability, while a granular security model controls users, roles, and predicate‑based access. Documentation and community channels support quick onboarding and ongoing maintenance.
Highlights
Native multi-model support (graph, document, key-value, full-text, geospatial)
SQL query language with ACID transaction guarantees
Multi-master distributed architecture for high availability
Fine-grained security with users, roles, and predicate policies
Pros
- High‑performance Java engine
- Single engine eliminates need for multiple databases
- Familiar SQL reduces learning curve
- Built‑in security and role management
Considerations
- Requires Java runtime
- Multi-model flexibility adds conceptual complexity
- Community smaller than leading NoSQL platforms
- No official managed cloud service

Fit guide
Great for
- Applications needing both graph traversals and document storage
- Teams familiar with SQL seeking NoSQL scalability
- Deployments requiring multi-master high availability
- Projects that benefit from built-in full-text and geospatial indexing
Not ideal when
- Environments without a Java runtime
- Use-cases demanding ultra-lightweight embedded databases
- Teams requiring extensive managed cloud offerings
- Projects that need a single-model specialized database for maximum performance
