When should I use FiloDB instead of Neo4j?

Distributed columnar analytics on time-series and event data using Apache Cassandra as storage. Combining fast time-range queries with Cassandra's horizontal scalability. IoT and metrics workloads needing efficient columnar storage on distributed Cassandra infrastructure

When should I use Neo4j instead of FiloDB?

Graph-native storage and Cypher querying for highly connected data like social networks and knowledge graphs. Relationship-heavy queries that would require many expensive JOINs in a relational database. Recommendation engines, fraud detection networks, and supply chain graph analytics

What are the main weaknesses of FiloDB?

Small community with limited documentation and few active production deployments. Inactive development — the project has not seen regular releases in recent years. Requires deep expertise to deploy and tune alongside a Cassandra cluster

What are the main weaknesses of Neo4j?

Not suitable for simple tabular, document, or time-series data workloads. Cypher query language is powerful but Neo4j-specific; skills don't transfer to other databases. Enterprise clustering and advanced features require a commercial license

How Python Data Engineers Use These Tools

FiloDB

Python data engineers working in observability infrastructure use FiloDB as a long-term storage backend for Prometheus metrics. Python scripts query FiloDB via its HTTP API to pull historical metric data for anomaly detection models or SLA reporting — enabling ML-driven monitoring use cases that require more data history than Prometheus retains locally.

Neo4j

Python data engineers connect to Neo4j using the neo4j Python driver or py2neo library to build knowledge graphs, fraud detection networks, and recommendation systems. Graph databases are used when relationships between entities are as important as the entities themselves — supply chain networks, social graphs, and dependency trees are natural fits. Engineers build ETL pipelines that extract relational data and load it into Neo4j as a graph for relationship-based analytics.
