orientCDB

orientCDB is an open-source, multi-model database designed to accommodate flexible data modeling and scalable deployments. It integrates graph, document, and key-value data representations within a single system, enabling applications to select the most suitable model for each workload while preserving cross-model relationships.

The storage and query infrastructure is modular to support varied workloads. orientCDB offers distributed operation through clustering and data replication, enabling horizontal scaling and high availability. It emphasizes pluggable storage engines and adaptive indexing to accelerate reads and graph traversals over large datasets.

Query language and APIs: The database provides a SQL-like language with extensions for graph traversal and document-style queries, along with client libraries for major programming languages and a RESTful API. This design aims to ease adoption for developers familiar with SQL while providing graph-oriented capabilities.

Deployment and use cases: orientCDB can be deployed on-premises or in cloud environments, with configuration options for multi-region replication and security controls. Common use cases include social networks and knowledge graphs, content management, IoT data stores, and other applications requiring flexible schemas and rich inter-model querying.

Governance and licensing: orientCDB is an open-source project maintained by a community of contributors. Development follows an open governance model with regular releases, documentation improvements, and paths for enterprise features under separate licenses.
