@app.on_event("startup") async def startup_event(): # Initialize any resources or connections here logging.info("Starting up...") @app.on_event("shutdown") async def shutdown_event(): # Clean up any resources or connections her…

However, I can offer some general guidelines and common pitfalls to watch out for when setting up middleware layers in FastAPI: ### General Guidelines for Middleware Optimization 1. **Minimize Overhead**: - Ensure that each middleware …

logging.info(f"Response status: {response.status_code}") logging.info(f"Total request processing took {time.time() - start_time:.4f} seconds") return response # Example endpoint @app.get("/items") async def read_items(): re…

- Use profiling tools like `cProfile` to identify bottlenecks in your middleware layers. - Set up monitoring using tools like Prometheus and Grafana to track the performance of your API over time and detect any regressions. 5. **Erro…

# Example endpoint @app.get("/api/v1/sensitive-data") def get_sensitive_data(user_role: str = Depends(restrict_access)): return {"message": "Sensitive data"} @app.get("/api/v1/sensitive-settings") def get_sensitive_settings(user_role: …

Here's an example of how you can implement these strategies: ```python from fastapi import FastAPI, BackgroundTasks import random import time from starlette.requests import Request from starlette.responses import JSONResponse from starlett…

``` #### nginx.conf ```nginx events {} http { upstream app_server { server web:8000; } server { listen 80; location / { proxy_pass http://app_server; proxy_set_header Host $hos…

lifespan="on", # Lifespan of the server proxy_headers=True, # Enable proxy headers ) # Run the server if __name__ == "__main__": uvicorn.run(config) ``` ### Step 2: Define Access Roles and Handle Authorization Define roles …

@app.route('/hybrid-search', methods=['GET']) @cache.cached(timeout=60, query_string=True) # Cache for 1 minute async def hybrid_search(): query = request.args.get('query') async with aiohttp.ClientSession() as session: …

sparse_results = {"results": [], "total_results": 0} return JSONResponse(content={"error_code": e.status_code, "message": e.detail}, status_code=e.status_code) try: dense_results = call_dense_…

Implement rate limiting to prevent abuse and ensure that the endpoint can handle 600 req/sec throughput. ```python from fastapi_limiter import FastAPILimiter from fastapi_limiter.depends import RateLimiter @app.on_event("startup") async d…

dense_results = call_dense_retrieval(query) except HTTPException as e: dense_results = {"results": [], "total_results": 0} return JSONResponse(content={"error_code": e.status_code, "message": e.detail}, status_co…

``` ### Explanation 1. **Dependency Injection**: Use dependency injection to pass the Redis client to the route handler. 2. **Error Handling**: Raise `HTTPException` for cache misses. 3. **Background Tasks**: Added a background task to si…

### 4. Monitor and Adjust Monitor the performance of your system during the re-encryption process and adjust the batch size or frequency of re-encryption tasks as needed. ### Example Implementation Let's walk through an example implement…

Implement conditional requests using `ETag` or `Last-Modified` headers to serve cached responses when the data hasn't changed. ### 4. **Client-Side Caching** Encourage client-side caching by setting appropriate cache control headers in you…

- `--timeout 2`: Sets the timeout to 2 seconds. ### Example Implementation with FastAPI If you prefer to use an asynchronous framework, here's an example using FastAPI: #### FastAPI Application ```python from fastapi import FastAPI, HTT…
