For aws-api, (how) can I specify http timeouts? Are there any defaults?

Using the core.async API you can use alts and timeout channels to implement client timeout

Well, I would really like to avoid core.async API. Besides, that doesn't set proper network socket timeouts, which is what I want to do.

I found :timeout-msec option for HttpClient protocol https://github.com/cognitect-labs/aws-api/blob/1a27e1e466e2f999cdd00d1738426f3d3c68e1e9/src/cognitect/aws/http.clj#L26 Would I need to implement my own http client?

There's probably a timeout in the bundled http client you can use also

I'm afraid I don't know how to specify/use that.

My best guess is that I would have to create my own instance via cognitect.http-client/create and pass the expected timeouts. https://github.com/tobias/cognitect-http-client/blob/main/src/cognitect/http_client.clj#L318-L319 look sensible; however I don't see the :socket-timeout option 😮

Yep. Use :http-client option when creating client

(unfortunately, no progress in 5 years 😞 )

You could I interpret that as indicating that core.async is how you customise client

Yeah they aren't treating http client as a fully baked API. We are using core Async API for timeouts. Works well. You can always do blocking read from core Async API so convert back to blocking with timeout
