When should I use Apache HBase instead of Redis?

Wide-column storage for sparse, large-scale data on top of HDFS in Hadoop environments. Random read/write access to billions of rows where Hadoop MapReduce batch access is insufficient. Time-series and log data with many columns per row and highly sparse values

When should I use Redis instead of Apache HBase?

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 Apache HBase?

Requires running HDFS and ZooKeeper alongside HBase — very heavy operational footprint. Python client (happybase) is a Thrift wrapper with limited feature coverage compared to the Java API. Effectively legacy for new projects; Bigtable, Cassandra, or ScyllaDB are common replacements

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

Apache HBase

Python data engineers use `happybase` or `phoenixdb` to interact with HBase from Python. A common pattern is using HBase as a fast random-access lookup store alongside a Hadoop batch pipeline — the Python service layer queries HBase for individual row lookups while the Spark job handles bulk aggregations on the same underlying HDFS data.

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.
