When should I use Apache Hudi instead of Apache Storm?

Incremental data ingestion into data lakes with upsert, delete, and CDC support on object storage. Change data capture workflows writing directly to S3 or ADLS in Parquet format. ACID transactions on large data lakes enabling record-level updates without full rewrites

When should I use Apache Storm instead of Apache Hudi?

Real-time computation on unbounded streams with guaranteed message processing semantics. Legacy real-time processing systems built before Flink and Spark Streaming became dominant. Low-latency stream topologies (spouts and bolts) where sub-second processing is critical

What are the main weaknesses of Apache Hudi?

Complex configuration for compaction, clustering, and timeline management requires expertise. Interoperability with query engines like Trino and Athena requires careful table property setup. Steeper learning curve than writing plain Parquet files; operational overhead is significant

What are the main weaknesses of Apache Storm?

Largely superseded by Apache Flink and Spark Structured Streaming for all new projects. JVM-based; Python support via Streamparse is a second-class experience with limitations. No built-in stateful processing — managing state requires external systems like Redis or HBase

How Python Data Engineers Use These Tools

Apache Hudi

Python data engineers use Hudi with PySpark to build CDC (Change Data Capture) pipelines on data lakes — ingesting database change events from Kafka and applying upserts to Hudi tables on S3 using `UPSERT` operation type. Hudi handles deduplication and merge semantics automatically, enabling mutable data lake tables without full partition rewrites.

Apache Storm

Python data engineers use Apache Storm via the streamparse library to write Storm topologies in Python. Storm is used for real-time event processing, fraud detection, and IoT telemetry pipelines where data must be processed and acted upon within milliseconds. While Kafka Streams and Flink have largely superseded Storm in new builds, it remains in production at organisations processing high-velocity event streams.
