Summary

FastAPI async patterns for building high-performance, concurrent APIs with optimal resource usage.

  • Covers async route handlers, database operations (SQLAlchemy, asyncpg, Motor, Tortoise ORM), and connection pooling strategies for efficient resource management
  • Includes real-time communication patterns: WebSockets with authentication and broadcasting, Server-Sent Events (SSE), and streaming responses for large files or generated content
  • Provides concurrent request handling with asyncio.gather for parallel operations, background tasks with BackgroundTasks, and async context managers for resource cleanup
  • Demonstrates performance optimization techniques including caching, batch operations, debouncing, and prefetching related data to minimize latency

Basic Async Route Handlers

Understanding async vs sync endpoints in FastAPI.

from fastapi import FastAPI
import time
import asyncio

app = FastAPI()

# Sync endpoint (blocks the event loop)
@app.get('/sync')
def sync_endpoint():
