Susheel Aroskar talks about Zuul Push, a scalable push notification service that handles millions of "always-on" persistent connections from all the Netflix apps running. He covers the design of the Zuul Push server and reviews the design details of the back-end message routing infrastructure that lets any Netflix microservice push notifications to any connected client.

Much better than watching "Design a Notification Service" System design interview videos.

The “ask client to close” due to TCP wait avoidance, is brilliant. Well done!

This talk is so good. Especially the mention of benchmarking numbers. m4.large ~ 8G,2vCPU = 84000 concurrent connections. ❤️
@mat822 3 роки тому
yes it is very good talk but it not clear what is the throughput of the system with 84K clients, I guess it is very low if he was saying the CPU was barely used.
@faizhalde2836 3 роки тому
@@mat822 the system does look io intensive (mostly network calls) so low cpu makes sense i think
@helloworld7313 2 роки тому
@@mat822 125 million users, 1 push notification per day, each notification takes 1KB 125000000*1024/86400 < 2MB/s negligible throughput. Of course they kill connections periodically, but still very low throughput system.

Amazing talks! I learn a lot from this video. "Ask client to close" is really brilliant. Randomized the connection time is also very impressive. I have seen random backoff algorithm, don't know it can also be used in this scenario.

nit pick here, but how does sharding for availability help in push registry feature checklist? Its because it protects by only some portion of connection server goes down?

Question : when you say client opens connection and stays connected to that server, wouldn't it talk to load balancer and not the actual server here? So even if you deploy new server behind that load balancer there won't be any issue of the connection closing and re-opening as you mentioned? Please shed some light if I am missing something here.

I think some confusion at ELB. ELB operates at Layer 4 which means at the TCP layer already.

How can they "push messaging" to Android with WebSocket while Google simply banned any push notification methods but FCM?
@lahmerilyas4430 10 місяців тому
This push mechanism is for users who are using the app. FCM is used for both forground/background usage.

I have only one request why the client depends on the server. I mean why this client-server mapping. What if the server is down then we need to migrate all the client-specific servers to a new server which is costly and may create issues like thundering. It's not we should make the server stateless with client requests and maybe only we should store client information in the push registry?? and when push notifications just randomly pick the server and send a message to the client id.
@TheNikhilbhoyar 2 роки тому
what is worse than thundering herd? its recurring thundering herd

what is the difference between push vs kafka messages/ message queues?
@maximecaron3133 2 роки тому
with push client subscribe to a small set of keys( movie name …). while with kafka there is a single log and client need to read all message that have been written to the log
