Timeout handling is typically delegated to the web server or custom middleware, which leaves the API layer without a documented cancellation signal. Streaming responses are supported via StreamingHttpResponse, but detecting client disconnect is not described a
Django Rest Framework provides CursorPagination to mitigate the performance degradation and data drift issues common with offset-based methods. While this approach ensures consistent results by using a unique ordering pointer, it inherently restricts the client to sequential navigation via next and previous page keys.
