Hi. What is a good way to answer http get query with stream of events. I mean, no content length, infinity long living query, which sometime print a line to output, if client is still there. call.respondOutputStream with explicit flushes seams to be working, but doesn't look suspend friendly. Won't it block more threads than needed?

You can try using the

call.respondBytesWriter {}

that uses a

ByteWriteChannel

under the hood.

But it still looks like blocking API, as lambda itself wouldn't be suspend.

The lambda is suspendable. What do you mean that it wouldn’t be suspend?

Hm. I need to recheck API. But anyway, writer.flush() is not suspend.
