ArangoDB

A native multi-model database engine that unifies documents, graphs, and key-values in a single C++ core using one query language (AQL).

ArangoDB eliminates complexity by handling JSON documents, complex graph relations, and key-value pairs within a single database instance. Its native multi-model architecture ensures ACID compliance and high performance without the data redundancy of polyglot persistence. Developers use ArangoDB Query Language (AQL) to join data across different models in one statement, reducing network overhead. With features like the SmartGraph module for sharding large datasets and the integrated ArangoSearch engine for full-text indexing, it scales horizontally to meet enterprise-grade demands.
