ISBN: 9798195243739 - async python mastery: building high-performance concurrent applications (5 Ergebnisse)

Paperback. Zustand: new. Paperback. Stop Letting Your Python Apps Wait Around. Make Them Fly.Your web scraper takes hours to crawl thousands of URLs. Your API server handles requests one at a time while users sit watching loading spinners. Your data pipeline processes records sequentially, wasting precious wall-clock time on the network.You've heard async programming could fix all of this. You've seen the async and await keywords. But the explanations either skip the fundamentals you actually need or drown you in low-level event-loop theory you'll never use.Async Python Mastery is the practical, no-magic guide that takes you from confused to confident.What You'll BuildFastAPI services that serve hundreds of concurrent requests on a single coreWeb scrapers that fetch thousands of pages in seconds, not hoursDatabase layers using async SQLAlchemy, asyncpg, and Motor that don't block on every queryProduction systems with proper timeouts, retries, circuit breakers, and graceful shutdownReal-world applications that mix async, threads, and processes intelligently What Makes This Book DifferentBuilt around real production code. Every example targets Python 3.11+ and uses modern patterns: asyncio.TaskGroup, asyncio.timeout(), FastAPI's lifespan context manager, and redis.asyncio. No deprecated APIs. No tutorial-grade fragments that fall over in production.Honest about trade-offs. You'll learn when async is the wrong choice. When threading wins. When multiprocessing is your only option. The book includes a Decision Matrix you'll come back to whenever you're starting a new project.Code-heavy, jargon-light. Every concept is grounded in code you can run. Every chapter ends with Quick Reference tables, Action Steps, and a "Coming Up" preview so you always know where you are.Inside You'll MasterHow the asyncio event loop actually schedules your tasks (and why blocking it kills performance)Coroutines, tasks, and the modern structured concurrency patterns from Python 3.11+Building production-grade async APIs with FastAPI, including lifespan management and dependency injectionAsync database operations with connection pooling, transactions, and N+1 query avoidanceHigh-throughput web scraping with semaphore-based rate limiting and exponential backoffReal-world patterns: aggregating multiple APIs, streaming responses, WebSockets, cachingConcurrency pitfalls: race conditions, missing awaits, session leaks, and the bugs type checkers can catchChoosing between async, threading, and multiprocessing for any workloadProduction deployment: Uvicorn workers, monitoring with Sentry, structured logging, graceful shutdown, Docker, and Nginx configuration Who This Book Is ForIntermediate Python developers who can write clean synchronous code but feel lost the moment async enters the picture. You don't need prior async experience-just comfort with Python fundamentals: functions, classes, decorators, exception handling, and the standard library.What You Get10 focused chapters across 200+ pages. Two appendices with quick-reference patterns and a common-patterns library. Real case studies drawn from production systems (composite, with the names changed but the bugs and trade-offs preserved). Code examples tested on Python 3.11 and 3.12.Stop fighting your code. Start writing Python that scales. This item is printed on demand.
