When should I use Apache Hudi instead of Apache Samza?

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 Samza instead of Apache Hudi?

Stateful stream processing tightly integrated with Apache Kafka and durable local state stores. Teams in the LinkedIn or Hadoop ecosystem needing large, persistent local state per partition. Long-running stateful jobs where RocksDB-backed local state provides fast key-value access

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 Samza?

Tightly coupled to Kafka and YARN; difficult to deploy and operate outside that ecosystem. Smaller community than Flink with fewer tutorials, integrations, and managed service options. Python API is minimal — primarily a Java and Scala framework with limited Python support

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 Samza

Python data engineers interact with Apache Samza primarily through its REST API or by bridging Python logic into Samza jobs via subprocess calls. More commonly, Python pipelines produce events to Kafka topics that Samza jobs consume for stateful aggregation — Python handles data ingestion and enrichment while Samza manages low-latency stateful stream processing at scale.
