When should I use FiloDB instead of Redis?

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 Redis instead of FiloDB?

Ultra-low-latency caching and session storage with sub-millisecond read and write times. Message brokering via Pub/Sub or Redis Streams for simple event-driven workloads. Leaderboards, rate limiting, and real-time counters using atomic data structures

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 Redis?

Data must fit in RAM — not suitable as a primary store for large datasets. Persistence options (RDB snapshots, AOF) add latency or disk I/O overhead. License changed to RSALv2/SSPL in v7.4; Valkey is the open-source fork maintained by the community

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.

Redis

Python data engineers use Redis via the redis-py library as a high-speed caching layer, rate-limit store, and task queue broker. Redis is the default broker for Celery-based task queues and is used by Apache Airflow for caching pipeline metadata. In data pipelines, Redis stores intermediate results, deduplication sets, and real-time leaderboards that would be too slow to query from a relational database on every request.
