Overview

Kickstart your journey into Python's asynchronous and reactive programming world with this comprehensive, hands-on guide. You'll learn to harness asyncio's event loop and RxPY's powerful observables to build high-performance, event-driven applications that scale with confidence from day one. What You'll Learn Initialize and manage the asyncio event loop, coroutines, Tasks, and async context managers Create, subscribe to, and transform RxPY Observables using operators like map, filter, flat_map, and buffer Bridge asyncio Futures and RxPY Observables for seamless push-and-pull data flows Implement error handling strategies: catch, retry, on_error_resume_next, and global exception policies Coordinate multiple schedulers (AsyncIO, ThreadPool, TestScheduler) for optimized concurrency Apply backpressure techniques to prevent overload in reactive pipelines Integrate OpenTelemetry tracing, Prometheus metrics, and Grafana dashboards for observability Design resilient architectures with retries, circuit breakers, and graceful degradation patterns Scale horizontally using multiprocessing, Dask, Redis, or Kafka for distributed event processing Test and debug with pytest-asyncio, RxPY's TestScheduler, faulthandler, and structured logging Hands-On Projects Build a real-time chat server that handles thousands of concurrent users with async WebSockets and reactive streams Process IoT sensor data, applying filters, windows, and aggregation in a live dashboard Develop a reactive web scraper that leverages backpressure to avoid overloading target sites Implement an asynchronous ETL pipeline ingesting data from APIs into a message broker Orchestrate microservices exchanging events over Redis or Kafka with fault-tolerant supervisors Who This Book Is For Python developers looking to move beyond synchronous scripts Backend engineers designing scalable, event-driven systems Architects and devops professionals integrating observability and resilience Students and self-learners seeking practical, production-ready examples Take the first step toward mastering asynchronous and reactive programming in Python. Build high-performance, event-driven applications with clarity and control!
