ArangoDB vs LevelDB

ArangoDB is an open-source multi-model database that combines document, graph, and key-value data models in a single engine. It uses AQL (ArangoDB Query Language) for querying across all data models and supports distributed deployments.

LevelDB is fast embedded key-value storage library from Google with ordered mapping from string keys to string values. It provides comprehensive features for databases workflows. The tool is actively maintained with regular updates and strong community/vendor support.
