When should I use Apache Spark Streaming instead of Zilla?

Micro-batch stream processing integrated with the Spark ecosystem using Structured Streaming API. Teams already using PySpark who want to add streaming with minimal new tooling or concepts. Combining historical batch data with real-time streams in a single unified Spark job

When should I use Zilla instead of Apache Spark Streaming?

API gateway for Kafka — exposing Kafka topics over REST, SSE, gRPC, or MQTT protocols. Bridging web clients and IoT devices to Kafka without building a custom intermediary service. Event-driven architectures needing protocol translation into and out of Kafka topics

What are the main weaknesses of Apache Spark Streaming?

Micro-batch architecture introduces latency compared to true streaming engines like Flink. Legacy DStream API is deprecated; migration to Structured Streaming is required for new work. JVM overhead and cluster management complexity remain significant operational challenges

What are the main weaknesses of Zilla?

Very niche use case; most teams use Confluent REST Proxy or custom services instead. Small community and limited documentation outside the vendor's own materials. Adds another infrastructure component to manage alongside an already complex Kafka deployment

How Python Data Engineers Use These Tools

Apache Spark Streaming

Python data engineers use Spark Structured Streaming via PySpark to process high-volume Kafka streams at scale. A streaming job reads a Kafka topic as a DataFrame, applies transformations (filtering, aggregations, joins with static data), and writes results continuously to Delta Lake or a database — using the same PySpark syntax as batch jobs.

Zilla

Python data engineers use Zilla to give non-Kafka consumers HTTP-based access to Kafka data — a Python REST client can read from or write to a Kafka topic without the Kafka client library. This simplifies event-driven microservice architectures where lightweight Python services need to participate in a Kafka-based pipeline without managing consumer group offsets.
