When should I use FiloDB instead of PostgreSQL?

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 PostgreSQL instead of FiloDB?

General-purpose relational database with advanced SQL, JSONB, and rich extension ecosystem. OLTP workloads needing ACID compliance, complex queries, full-text search, and extensibility. Teams who want a battle-tested open-source database that scales from prototype to production

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 PostgreSQL?

Horizontal scaling requires extensions like Citus or external sharding — not built in. Write throughput under heavy concurrent load is lower than some NoSQL alternatives. Requires DBA expertise for production tuning: vacuuming, indexing, and connection pooling

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.

PostgreSQL

PostgreSQL is the most popular database target for Python data pipelines. Engineers use `psycopg2` or `asyncpg` for direct connections, SQLAlchemy for ORM-based access, and `pd.read_sql()` for pulling query results into DataFrames. PostgreSQL's JSONB support is frequently used to store semi-structured API responses before they are normalized into relational tables.
