How will this work in multiple pots, how this this arraylist value will be captured in another pots

[@prasannanjaneyadachineni8570]

Very good tutorial. Can this pattern be used for exchanging large data over http ?(instead of using kafka - as it is not forever subscription and , Instead of waiting for response on restAPI which might take long time)

[@centurion3708]

I've a couple of events that should trigger different callback, but when i add more than one listener to the eventsource, only the first listener works, the other two are never trigered

[@javagrowth6221]

Hey better use kafka for real World usecase

Is a grade video tutorials for SSE in spring. but i confused something there. We are storing SseEmitter in List and add SseEmitter object on "/subscribe". but what will happen if there are million of user subscribe the sse and List will take large memory resource until they unsubscribe SSE. or is there a way to store these List for more efficient way?

[@javagrowth6221]

Thanks for support. If many users you have yo use kafka or rabbitmq but in my opinion you shoudlt better use kafka

[@prakashkoppal2614]

If I hit from postman then only 'dispatchEvent' method is working. But If I call the same method using Kaka , it is not working. Please help me how to solve it ?

Hi javagrowth,
Wonderful explanation , Is SSE suitable for multi instance environment..?

[@javagrowth6221]

Ye Sire, but i recommand Kafka :), i didn't use SSE in multi instance environment, but Kafka is Born for multi instance !

[@kiranchoudhari81]

Can this be used to share the status of asynchronous task running in background.

[@javagrowth6221]

yes but take a look at RabbitMQ and other Pub / Sub stuffs because you can't handle all on your running Spring Boot instances.

How to use SSE for windows notification?

[@javagrowth6221]

on Windows OS ? like basic desktop notification ?
If it's the case you have to use other environment like SWT / JFace ...

Good example to learn basics of Sse but it is full of worst practices. This can't be used in production.
