Кратко

ArangoDB is a multi-model database supporting documents, graphs, and key-value data in a single platform. Unlike MongoDB (documents only) or Neo4j (graphs only), ArangoDB uses AQL (Arango Query Language) to query across all models. Advanced practitioners design schemas for complex relationship data, optimize graph traversals, and integrate with recommendation systems and knowledge graphs. Demand is growing as companies build more complex data systems. Senior ArangoDB engineers earn $120k-180k.

Что такое ArangoDB Multi-Model

ArangoDB is a multi-model database combining document storage, graph database, and key-value capabilities. One unified query language (AQL) for all models. Data stored as JSON documents; relationships expressed as edges forming a graph. Advanced practitioners design schemas leveraging all three models, optimize complex traversals, and build systems (recommendations, knowledge graphs, MDM) that would require multiple databases separately.

❓ Частые вопросы

▶Why use ArangoDB instead of MongoDB + Neo4j?
Single database = simpler stack, one team manages it. AQL unifies document and graph queries. Transactional consistency across both models. MongoDB + Neo4j = separate tools, data sync complexity.
▶Is ArangoDB as fast as Neo4j for graph queries?
Neo4j is optimized for pure graph (very fast). ArangoDB is optimized for mixed workloads. For heavy graph analytics (PageRank, shortest path), Neo4j still wins. For mixed doc + graph, ArangoDB is simpler.
▶What's a good use case for ArangoDB?
Recommendation systems (user-product graphs + preferences docs), knowledge graphs (entities + relationships), master data management (hierarchical + relational), social networks.
▶How do I query documents and graphs together?
AQL supports joins across document and graph data. Example: SELECT user doc + friend graph + friend preferences in one query.
▶Can I use ArangoDB as a primary database?
Yes, with ACID guarantees and replication. Not as mature as PostgreSQL in enterprise, but production-ready. Better for new systems than migrations.
▶What's Pregel in ArangoDB?
Distributed graph processing engine. Run algorithms (PageRank, shortest path, community detection) on large graphs. Useful for recommendations and analytics.
▶How do I model relationships in ArangoDB?
Two options: nested documents (denormalization) or edges (graph). Nested for simple relationships, edges for complex/variable relationships. Use both in same schema.
