Streaming Backend Data Source Plugin

Hi, I am trying to develop a backend data source plugin using grafana-sdk-go. I have huge data to call, so it takes a lot of time to query.
I heard about streaming data while query is going on.
How can i do streaming in backend data source plugin? Is there any way, my data get stream as soon as i get my first chunk of data?

??? Any Answers for this??? All i could search is through typescript code. but from backend sdk, no answers…
