Streaming Data Pipeline for ML

Streaming Data Pipeline for ML

Architecture Overview

This reference architecture provides a comprehensive blueprint for implementing a production-grade streaming data pipeline optimized specifically for machine learning applications. The architecture addresses key challenges in real-time ML data processing:

  • Low-latency data ingestion from diverse sources
  • Real-time feature engineering and transformation
  • Stateful processing for time-window aggregations
  • Schema evolution and version management
  • Stream-based model training and online inference
  • End-to-end monitoring and observability

Core Components

The streaming data pipeline architecture consists of several integrated components:

Event Source Integration

Flexible connectors for ingesting real-time data from databases, APIs, IoT devices, and message queues with schema validation and transformation.

Stream Processing Engine

Scalable processing framework for real-time transformations, aggregations, and feature engineering with exactly-once processing guarantees.

Feature Computation Layer

Specialized components for real-time feature engineering, including windowed aggregations, time-series processing, and feature normalization.

Streaming ML Serving

Fast-path serving infrastructure for low-latency model inference integrated directly into the streaming pipeline with monitoring and feedback loops.
