When should I use ArangoDB instead of Couchbase?

Multi-model database supporting documents, graphs, and key-value in a single system. Applications that need both document queries and graph traversals without running two databases. AQL (ArangoDB Query Language) for flexible multi-model data access in one query language

When should I use Couchbase instead of ArangoDB?

Mobile data sync and offline-first applications using Couchbase Lite on iOS and Android. JSON document store with N1QL SQL-like query language for flexible, schema-optional data models. High-availability key-value and document access with sub-millisecond read latency

What are the main weaknesses of ArangoDB?

Multi-model approach can underperform purpose-built document (MongoDB) or graph (Neo4j) stores. Smaller community than MongoDB or Neo4j for their respective specialized use cases. Production deployment and horizontal scaling require careful planning and tuning

What are the main weaknesses of Couchbase?

Full enterprise features require a commercial license; Community Edition is significantly limited. N1QL query performance depends heavily on correct index design for each access pattern. Smaller community than MongoDB for general document store use cases

How Python Data Engineers Use These Tools

ArangoDB

Python data engineers use `python-arango` to work with ArangoDB's multi-model capabilities. Graph traversal queries in AQL make it straightforward to compute network metrics on relationship datasets — engineers build Python scripts that query ArangoDB for entity connections and enrich documents with graph-derived features for ML pipelines.

Couchbase

Python data engineers use the `couchbase` SDK to store and retrieve JSON documents representing pipeline entities — user profiles, product catalogs, or session data. N1QL lets engineers run SQL-like analytical queries from Python without schema migrations, and the full-text search integration enriches ingested documents with relevance-scored lookup capabilities.
