Learn how to process real-time data streams with ByteWax, an open-source Python framework. Explore stream processing concepts, challenges, and practical implementation strategies.
-
ByteWax is an open-source, Python-native stream processing framework built on a Rust engine that enables real-time data processing
-
Stream processing differs from batch processing by handling continuous, unbounded data as it arrives rather than processing defined sets of data
-
Real-time data processing means handling data as soon as it’s generated, with sub-second latency requirements depending on the use case
-
Key challenges in stream processing include:
- Handling time windows and late-arriving data
- Managing state across partitions
- Scaling processing across multiple workers
- Ensuring fault tolerance and recovery
- Maintaining data ordering
-
ByteWax features:
- Can run locally or scale on Kubernetes
- Supports various input sources (Kafka, WebSockets, HTTP streams)
- Provides windowing and aggregation capabilities
- Handles state management and recovery
- No vendor lock-in
- Works with the Python ecosystem
-
Stream processing operations include:
- Input connectors for data sources
- Map operations for transformations
- Window operators for time-based aggregations
- Fold operations for accumulating state
- Partitioning for parallel processing
-
Data flows in ByteWax are represented as directed acyclic graphs (DAGs) with nodes for each processing step
-
ByteWax can handle both streaming and batch processing scenarios, though it’s designed streaming-first
-
Common use cases include:
- IoT sensor data processing
- Social media analytics
- Manufacturing telemetry
- Financial market data
- Real-time monitoring
-
The framework supports running on various platforms from single Raspberry Pis to distributed cloud environments
