Such a coincidence, was just learning about Pub/Sub and Cloud Tasks (Queues) in GCP. This is valuable.

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DXTHb9TqJOs.html can i ask ? ive built message queue service using rabbitMq. as you said, once the request has been received by the server, we can sent the response to the client with identifier, so they can come back to check the condition for that request. talking about channel, so in this approach you talk about, we set the client to subs to same channel as the server use ? and there wont be any request response to check the condition for that request ? . for my case, iam still using request response for the client to check the condition of thier request before, and for the ux its really annoying for me (?) because they have to refersh the request to check the updates

Half of the comments be like: Damn, the timing of this video, I was just reading about this. Holy mother of coincidences. Also, it's not a 44 minutes lecture, it's [44 / play speed] minutes lecture. I recently gave a system design interview, had this been uploaded earlier, I would have nailed it.

can you use rabbitmq and kafaka here? im asking because kafka is more for streaming? or can you tune kafka to work like rabbitmq?

@ibknl1986 3 года назад

@colinmaharaj 2 года назад

I did my own disk back queues years ago. It uses a get/set/delete logic. The producer sets a value, the consumer gets it and the consumer deletes it once it has validated it has gotten the data correctly. Also it's FIFO based and there is no data loss in a power outage

@hemanthaugust7217 3 месяца назад

for request-response, you mentioned that client/server have to be running as a Con. When you use Queue, both Client & Queue have to be running. So, we just shifted the point of failure from server to queue, that's all. How is this not a con for MQ?

@ivandrofly Год назад

Thanks

@alek282 3 года назад

For request/response model, do we not solve the issue of blocked requests with event based architectures? ie in JavaScript you encapsulate requests / responses with promises. So if you send a request, you are free to do other things on the client. You are still blocked on that particular request in a sense but you are free to report some feedback to the user

@hnasr 3 года назад

Good question, javascript promises only provide a client side asynchronous behavior, the backend is still synchronously processing your request. This video describes the asynchronousity on the backend And if you are taking about JS promises on the backend than it depends on workload. Most workloads will go on the mainthread which will still execute requests synchronously and block. More here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gMtchRodC2I.html

انت راجل ميه ميه.. سؤال.. بالنسبة للمثال بتاع اليوتيوب uploading video لو الففيديو حجمه كبير 2جيجا او 4 مثلا هيكون سهل على ال message broker يبعته في ال queue لل consumer ؟ اقصد حجم الملف مش هيعمل مشكلة؟

سؤال ممتاز، يعتمد اذا قررت حفظ الفيديو في المسج كيو ام لا. شخصيا افضل حفظ الملف في blob ستور ووضع وصله في الكيو

ME: "Hussein are you telling me there is something better than that where the client can go offline and the server can go offline, and still they can communicate?" Hussein: Yes, Quantum-Psychic-Biological computer. It is not on or off because it is biological, It is multidimensional and communicates with brainwaves even between dimensions. Happy April fools!

The whole thing was waffle, lacked any actual facts and the more i think about it - it was entirely useless.. I’m not sure if this was aimed at junior developers or something but anyone with at least 6 months dev on their CV needs to go elsewhere for a proper grown up answer
