- ArangoDB is an open-source database that supports graph, document, and key-value data models and provides a unified query language for handling both graph and relational-style queries.
- Reviewers appreciate ArangoDB's user-friendly interface, its compatibility with schema-less design, the flexibility as a graph database, and the ability to write JSON-first queries using AQL.
- Users mentioned that the management and operations on collections and databases using AQL are weak, the documentation could be improved, and there is a degree of lock-in due to the unified query language.
