How would you create a web API with streaming input and output (eg stocks monitoring system) without tools like Kafka and Spark?

Maybe using websocket? Or Redis pubsub feature?

I also thought first of websockets. gRPC is also worth looking into. Or maybe GraphQL streaming, don't know how that works nowadays.

Websockets sounds a great idea. And it is relatively easy to implement a WS client/server.

I have never heard GQL streaming and redis pubsub. Will totally look into

Thank you guys

Thank you Nico. Not sure if long polling is a viable option in my book, but I will totally try the rest :)

My first choice would probably be WebSockets, but it might be worth a look at server-sent events for a possible simpler solution.
