    Really appreciated how you explained web sockets in comparison with HTTP Requests, making the exact point of utilizing web sockets stand out. That really helped me understand much better🙌

    But you haven't explained *how* it works. Not even a bit. Like what is behind those well-known WS interfaces? What is in the TCP package? Is it any special for WS? Do we need a URL to establish a connection? How to distinguish one connection from another one? Is there a notion of a cookie? How does the session work in the context of WS-based service? How does load balancing work with WS connections? What is the usual limit on the number of WS connections? Is it a number of opened file descriptors? What it depends on?

    Thanks for the feedback with specific examples. While these are good question, this video was made for System Design Interviews. To our knowledge, this level of detailing on web-sockets is not required in any of the Tier1/Tier2 Tech companies from System Design perspective, unless one is applying for a speciality position. Based on my market research, I may plan to deep dive on websockets in future. Thanks again!

    whats the best way to track websocket payload acknowledgement from frontend? (given we can't do it with the same websocket connection)

  • @ByteMonk

    @ByteMonk

    11 ай бұрын

    When you cannot directly track WebSocket payload acknowledgments using the same WebSocket connection, you can implement a custom acknowledgment mechanism using a combination of techniques. 1. Create a Unique Identifier for Each Payload: Before sending a payload from the frontend, assign a unique identifier (message ID) to each payload. This ID will help you correlate the acknowledgments received from the backend with the original payloads sent from the frontend. 2. Use a Separate Channel for Acknowledgments: Set up a separate communication channel between the frontend and backend. This can be another WebSocket connection, an HTTP REST API, or any other messaging protocol that suits your application. 3. Send Payloads and Wait for Acknowledgments: When sending a payload from the frontend to the backend via the primary WebSocket connection, store the payload's unique identifier along with its content in a local data structure (e.g., a map). 4. Backend Processing and Acknowledgment: On the backend, process the received payload and perform the required actions. After the backend has processed the payload successfully, it sends an acknowledgment message back to the frontend via the separate communication channel, containing the unique identifier of the processed payload. 5. Frontend Acknowledgment Handling: When the frontend receives an acknowledgment, it can use the unique identifier in the acknowledgment message to identify the corresponding payload in the local data structure and mark it as acknowledged. You can remove the entry or update its status in the map.

    It was a nice video, but it barely explained "How Web Sockets work", only in 3:45 to 4:18. Almost all of the video was actually about "What are Web Sockets", focusing mainly on a comparison between polling and sockets, which was well presented, but wasn't supposed to be the topic of the video promised by the title.

    it is important to know the motivation for why web socket exists before we learn web sockets. What problem is it solving and why do we need it?
